  • A Physician Shortage, But Too Many Radiologists

    Alessandra Simmons
    1 Mar 2015 | 8:00 am
    If you listen to the medical community, there’s a physician shortage brewing. By 2020, the country will need 91,500 additional doctors. By 2025, that figure rises to 130,600 according to the Association of American Medical Colleges (AAMC). Where does radiology fit into that? At its heyday, around 2001–2003, radiologists were in high demand. As one of the most requested specialist searches by national health care search firm Merritt Hawkins, radiology is no  longer in their top 20.

  • Affordable Care Act: Radiologists Need to Define Quality

    Alessandra Simmons
    27 Feb 2015 | 8:00 am
    A lot of people that aren’t in health care think that the Affordable Care Act was put in place to insure the uninsured, but its real goal is to lower the cost of health care from the government’s perspective, according to Brian Baker of Carealytics, in an interview with Diagnostic Imaging at AHRA 2014. The trend of growth in the population and the cost of health care is quickly unsustainable, Baker said. In addition to the rising spend in health care, “we’re finding new and better ways to make diagnostic imaging more appropriate and more beneficial for physicians, and it’s going to…

    Alessandra Simmons
    23 Feb 2015 | 8:00 am
    On January 26, 2015 the Department of Health and Human Services (HHS) announced two ambitious goals that have a significant impact on radiology: One half of all Medicare payment to physicians and hospitals will be made through alternative payment models (ie, medical homes and accountable care organizations) by 2018 and 85% of all fee-for-service payments will be tied to quality or value by 2016, with 90% by 2018. Shifting from fee-for-service reimbursement in Medicare to a pay-for-performance model has been long been an aspiration of HHS. However, this is the first time HHS has set explicit…

  • Comparison of Spin-Echo and Gradient-Echo T1-Weighted and Spin-Echo T2-Weighted Images at 3T in Evaluating Term-Neonatal Myelination [PEDIATRICS]

    Tyan, A. E., McKinney, A. M., Hanson, T. J., Truwit, C. L.
    11 Feb 2015 | 8:01 am
    SUMMARY: A prior clinical report of 3T MR imaging in subsequently healthy very premature neonates imaged at term-equivalent age found that both gradient recalled-echo–T1WI and spin-echo–T2WI showed higher rates of myelinated structures, compared with spin-echo–T1WI. The current study set out to assess those rates on the same sequences at 3T in term neonates and thus consisted of 16 term neonates with normal-appearing MR imaging findings who subsequently had normal findings at clinical follow-up. Two neuroradiologists independently assessed 19 structures in those infants on…

  • Isolated ventriculomegaly on prenatal ultrasound: What does fetal MRI add?

    Tejaswi Kandula, Michael Fahey, Rebecca Chalmers, Andrew Edwards, Paul Shekleton, Mark Teoh, Jenni Clark, Stacy K. Goergen
    2 Mar 2015 | 12:29 am
    Abstract IntroductionCerebral ventriculomegaly is one of the most commonly detected fetal anomalies at the midtrimester ultrasound. Current evidence suggests that magnetic resonance imaging (MRI) is indicated when the isolated ventriculomegaly (IVM) on ultrasound is severe (>15 mm), but there is less agreement when IVM is mild or moderate (10–15 mm). The current study aimed to determine the frequency and nature of additional findings on MRI in IVM and their relationship to the severity of VM and gestational age. MethodsData were gathered prospectively from all pregnant women with…

  • Voting for Image Scoring and Assessment (VISA) - theory and application of a 2¿+¿1 reader algorithm to improve accuracy of imaging endpoints in clinical trials

    Klaus Gottlieb
    19 Feb 2015 | 4:00 am
    Independent central reading or off-site reading of imaging endpoints is increasingly used in clinical trials. Clinician-reported outcomes, such as endoscopic disease activity scores, have been shown to be subject to bias and random error. Central reading attempts to limit bias and improve accuracy of the assessment, two factors that are critical to trial success. Whether one central reader is sufficient and how to best integrate the input of more than one central reader into one output measure, is currently not known.In this concept paper we develop the theoretical foundations of a reading…
  • Valid and efficient manual estimates of intracranial volume from magnetic resonance images

    Niklas Klasson
    17 Feb 2015 | 4:00 pm
    Background: Manual segmentations of the whole intracranial vault in high-resolution magnetic resonance images are often regarded as very time-consuming. Therefore it is common to only segment a few linearly spaced intracranial areas to estimate the whole volume. The purpose of the present study was to evaluate how the validity of intracranial volume estimates is affected by the chosen interpolation method, orientation of the intracranial areas and the linear spacing between them. Methods: Intracranial volumes were manually segmented on 62 participants from the Gothenburg MCI study using…
  • Hibernoma ¿ two patients with a rare lipoid soft-tissue tumour

  • Myocardial function in aortic stenosis ¿ insights from radial multilayer Doppler strain

    Dana Cramariuc
    18 Feb 2015 | 4:00 pm
    Background: Left ventricular (LV) radial tissue Doppler imaging (TDI) strain increases gradually from the subepicardial to the subendocardial layer in healthy individuals. A speckle tracking echocardiography study suggested this gradient to be reduced in parallel with increasing aortic stenosis (AS) severity. Methods: We used TDI strain in 84 patients with AS (mean age 73 ± 10 years, 56% hypertensive) for superior assessment of layer strain. 38 patients had non-severe and 46 severe AS by aortic valve area corrected for pressure recovery. Peak systolic radial TDI strain was measured in…

  • Measurements of carotid intima media thickness in non-invasive high-frequency ultrasound images: the effect of dynamic range setting

    Mario Gaarder
    26 Jan 2015 | 4:00 pm
    Background: Carotid intima media thickness (CIMT) measured with ultrasound (US) is widely used as biomarker for arteriosclerosis and as surrogate endpoint in interventional studies to assess efficacy of drug therapies. Strict US protocols are necessary to ensure reproducibility. The range of US signal intensities used for image formation, the dynamic range (DR), is rarely reported in studies and little is known about its effect on CIMT measurements in humans. The purpose of this study was to quantify the impact of DR on measurements of CIMT. Methods: US was used to examine 313 carotid…

    Thromboembolic diseases are among the most prevalent medical problems today and cause stroke, myocardial ischemia, acute limb ischemia, and pulmonary embolism. Various treatment modalities exist, ranging from medical therapy to endovascular techniques. In the management of a thromboembolic condition causing a threatened limb, common options for treatment include surgical thromboembolectomy, percutaneous thrombectomy, and/or thrombolysis. In recent decades, many mechanical thromboembolectomy devices have become commercially available and have proven to be useful in the treatment of acute…
  • Early Introduction of IR to Premedical and Medical Students: Initiatives at a Single U.S. Institution

    Erica S. Alexander, Jason T. Machan, Sun H. Ahn
    28 Feb 2015 | 4:00 pm
    In 2012, the American Board of Medical Specialties approved the American Board of Radiology’s application for a dual primary certificate in interventional radiology (IR) and diagnostic radiology (DR) (1). This approval not only designated IR as the 37th primary certificate in the United States, but it also marked a milestone in recognizing that IR is a unique area of medicine that requires a distinct skill set for future trainees. The new primary certificate will result in many vascular and IR (VIR) fellowship positions being converted to integrated IR/DR residency positions.

    28 Feb 2015 | 4:00 pm
    Various types of contrast agents are used in angiographic procedures. Nonionic agents are preferred over other agents because of fewer adverse effects. Although nonionic contrast agents (NICAs) are safer compared with ionic contrast agents, their individual adverse effects differ. We report a patient in whom blood aggregation occurred when the patients blood was mixed with an iopromide-containing agent at the time of coronary angiography.

  • The neural correlates of volitional attention: A combined fMRI and ERP study

    Jesse J. Bengson, Todd A. Kelley, George R. Mangun
    2 Mar 2015 | 8:49 pm
    Abstract Studies of visual-spatial attention typically use instructional cues to direct attention to a relevant location, but in everyday vision, attention is often focused volitionally, in the absence of external signals. Although investigations of cued attention comprise hundreds of behavioral and physiological studies, remarkably few studies of voluntary attention have addressed the challenging question of how spatial attention is initiated and controlled in the absence of external instructions, which we refer to as willed attention. To explore this question, we employed a trial-by-trial…

    2 Mar 2015 | 2:53 am
    Abstract fMRI is increasingly implemented in the clinic to assess memory function. There are multiple approaches to memory fMRI, but limited data on advantages and reliability of different methods. Here, we compared effect size, activation lateralisation, and between-sessions reliability of seven memory fMRI protocols: Hometown Walking (block design), Scene encoding (block design and event-related design), Picture encoding (block and event-related), and Word encoding (block and event-related). All protocols were performed on three occasions in 16 patients with temporal lobe epilepsy (TLE).
  • Connectivity and functional profiling of abnormal brain structures in pedophilia

    Timm B. Poeppl, Simon B. Eickhoff, Peter T. Fox, Angela R. Laird, Rainer Rupprecht, Berthold Langguth, Danilo Bzdok
    1 Mar 2015 | 11:41 pm
    Abstract Despite its 0.5–1% lifetime prevalence in men and its general societal relevance, neuroimaging investigations in pedophilia are scarce. Preliminary findings indicate abnormal brain structure and function. However, no study has yet linked structural alterations in pedophiles to both connectional and functional properties of the aberrant hotspots. The relationship between morphological alterations and brain function in pedophilia as well as their contribution to its psychopathology thus remain unclear. First, we assessed bimodal connectivity of structurally altered candidate regions…
  • The effect of ageing on fMRI: Correction for the confounding effects of vascular reactivity evaluated by joint fMRI and MEG in 335 adults

    Kamen A. Tsvetanov, Richard N. A. Henson, Lorraine K. Tyler, Simon W. Davis, Meredith A. Shafto, Jason R. Taylor, Nitin Williams, Cam-CAN, James B. Rowe
    27 Feb 2015 | 7:08 am
    Abstract In functional magnetic resonance imaging (fMRI) research one is typically interested in neural activity. However, the blood-oxygenation level-dependent (BOLD) signal is a composite of both neural and vascular activity. As factors such as age or medication may alter vascular function, it is essential to account for changes in neurovascular coupling when investigating neurocognitive functioning with fMRI. The resting-state fluctuation amplitude (RSFA) in the fMRI signal (rsfMRI) has been proposed as an index of vascular reactivity. The RSFA compares favourably with other techniques…
  • Measuring vascular reactivity with breath-holds after stroke: A method to aid interpretation of group-level BOLD signal changes in longitudinal fMRI studies

    Fatemeh Geranmayeh, Richard J.S. Wise, Robert Leech, Kevin Murphy
    27 Feb 2015 | 7:05 am
    Abstract Blood oxygenation level-dependent (BOLD) contrast functional magnetic resonance imaging (fMRI) is a widely used technique to map brain function, and to monitor its recovery after stroke. Since stroke has a vascular etiology, the neurovascular coupling between cerebral blood flow and neural activity may be altered, resulting in uncertainties when interpreting longitudinal BOLD signal changes. The purpose of this study was to demonstrate the feasibility of using a recently validated breath-hold task in patients with stroke, both to assess group level changes in cerebrovascular…

  • The right atrium, a forgotten cardiac chamber: An updated review of multimodality imaging

    Marijana Tadic
    1 Mar 2015 | 11:18 pm
    ABSTRACT Despite several limitations, two-dimensional echocardiography (2DE) is the standard method for assessing the right atrium (RA) in everyday clinical routine. Cardiac magnetic resonance remains the current “gold standard” for RA visualization and volume quantification. The development of 2DE-derived strain imaging has enabled assessing RA deformation and phasic function in various pathologic conditions. Three-dimensional echocardiography was demonstrated to be more accurate and reproducible than 2DE for cardiac chamber quantification, while also allowing the evaluation of RA phasic…

    ABSTRACT Serous surface papillary borderline ovarian tumors (SSPBOTs) are a rare morphologic variant of serous ovarian tumors that are typically confined to the ovarian surface, while the ovaries themselves tend to appear normal in size and shape. In this report, we describe the findings from five premenopausal women diagnosed with SSPBOTs, in whom ultrasound showed grossly normal ovaries that were partially or wholly covered with irregular solid tumors. In all five cases, histologic examination showed evidence of borderline serous tumors. These findings demonstrate that SSPBOTs can be…

    20 Feb 2015 | 2:41 am
    ABSTRACT PurposeThe most common cause of acute scrotum in prepubertal boys is torsion of the testicular or epididymal appendages. The purpose of this retrospective study was to characterize the features of these lesions as viewed on sonographic (US) and color Doppler US examination. MethodsDuring a 220-week period, 527 male patients 0–17 years old had been referred from the pediatric emergency department for scrotal US evaluation. Torsion of the appendix testis or appendix epididymis had been diagnosed in 19 (3.6%) patients, 3–14 years old (mean, 9.4 years); those patients became our…

    ABSTRACT PurposeOur aim was to prospectively analyze the use of contrast-enhanced ultrasound (CEUS) in the quantitative assessment of the response of uveal melanoma (UM) to gamma-knife radiosurgery (GKR), investigating whether changes in tumor vascularization precede thickness reduction, which on average occurs at 12 months after GKR. MethodsTen patients with UM treated with GKR underwent sonography (US) and CEUS at baseline and at 3, 6, and 12 months after GKR. The transverse diameter, thickness, and quantitative parameters of the UM (ie, area under the curve in the wash-in phase, wash-in…

    ABSTRACT PurposeThe task of ultrasound-guided vessel cannulation can be technically difficult. Needle guides have been designed to facilitate vessel puncture. We aimed to identify and compare the learning curves of participants performing vessel puncture with conventional freehand (FH) and needle guide–assisted (NG) techniques. MethodsThirty-six participants were randomly allocated to either the FH or the NG group. They were asked to consecutively perform as many as 30 vessel punctures on a simulated phantom model. Quantitative metrics (time taken and number of skin and posterior-wall…

  • CAPIRI-IMRT: a phase II study of concurrent capecitabine and irinotecan with intensity-modulated radiation therapy for the treatment of recurrent rectal cancer

    Gang Cai
    27 Feb 2015 | 4:00 pm
    Background: This study investigated the local effect and acute toxicity of irinotecan and capecitabine with concurrent intensity-modulated radiation therapy (IMRT) for the treatment of recurrent rectal cancer without prior pelvic irradiation. Methods: Seventy-one patients diagnosed with recurrent rectal cancer who did not previously receive pelvic irradiation were treated in our hospital from October 2009 to July 2012. Radiotherapy was delivered to the pelvis, and IMRT of 45 Gy (1.8 Gy per fraction), followed by a boost of 10 Gy to 16 Gy (2 Gy per fraction), was delivered to the…
  • A cell-based high-throughput screening assay for radiation susceptibility using automated cell counting

    Jasmina Hodzic
    26 Feb 2015 | 4:00 pm
    Background: Radiotherapy is one of the mainstays in the treatment for cancer, but its success can be limited due to inherent or acquired resistance. Mechanisms underlying radioresistance in various cancers are poorly understood and available radiosensitizers have shown only modest clinical benefit. There is thus a need to identify new targets and drugs for more effective sensitization of cancer cells to irradiation. Compound and RNA interference high-throughput screening technologies allow comprehensive enterprises to identify new agents and targets for radiosensitization. However, the gold…
  • Ion therapy of prostate cancer: daily rectal dose reduction by application of spacer gel

    Antoni Rucinski
    26 Feb 2015 | 4:00 pm
    Background: Ion beam therapy represents a promising approach to treat prostate cancer, mainly due to its high conformity and radiobiological effectiveness. However, the presence of prostate motion, patient positioning and range uncertainties may deteriorate target dose and increase exposure of organs at risk. Spacer gel injected between prostate and rectum may increase the safety of prostate cancer (PC) radiation therapy by separating the rectum from the target dose field. The dosimetric impact of the application of spacer gel for scanned carbon ion therapy of PC has been analyzed at…

    PurposeThe aim of this study was to evaluate the salvage radiotherapy outcome in patients with local recurrent esophageal cancer after radical radiochemotherapy (RCT). Methods: A total of 114 patients with local recurrent esophageal squamous cell carcinoma after initial radical RCT were retrospectively analyzed. Fifty-five (55) patients belonged to the salvage radiotherapy group (SR group) and 59 patients to the non-salvage radiotherapy group (NSR group). Results: The median survival time after-recurrence was 4 months in all patients. The 1, 2, 3 year overall survival (OS) rates were 83.6%,…
  • Dose calculation of Acuros XB and Anisotropic Analytical Algorithm in lung stereotactic body radiotherapy treatment with flattening filter free beams and the potential role of calculation grid size

    Baotian Huang
    25 Feb 2015 | 4:00 pm
    Background: The study aimed to appraise the dose differences between Acuros XB (AXB) and Anisotropic Analytical Algorithm (AAA) in stereotactic body radiotherapy (SBRT) treatment for lung cancer with flattening filter free (FFF) beams. Additionally, the potential role of the calculation grid size (CGS) on the dose differences between the two algorithms was also investigated. Methods: SBRT plans with 6X and 10X FFF beams produced from the CT scan data of 10 patients suffering from stage I lung cancer were enrolled in this study. Clinically acceptable treatment plans with AAA were recalculated…
