  • Do Docs Even Follow USPSTF Breast Cancer Screening Guidelines?

    Alessandra Simmons
    3 May 2015 | 8:30 am
    Most surgeons continue to recommend annual screening mammography for women once they have turned 40 years old, despite current USPSTF guidelines of biennial screening mammography between ages 50 and 74, according to a presentation at the American Roentgen Ray Society 2015 Annual Meeting (ARRS) in Toronto, Canada. The USPSTF released an updated draft recommendation of guidelines this past week, which remain largely unchanged. Source: UBM Partner Site Diagnostic Imaging - For full article, please click here.

    29 Apr 2015 | 8:00 am
    Breast cancer screening can save lives, but the economic impact of false-positive mammography results and breast cancer over-diagnosis must be discussed, according to a study published in the journal Health Affairs. The over-diagnosis rate for breast cancer varies, including 22% of all breast cancer screenings in Canada and 22% to 31% in the US, the authors wrote. However, not much is known about the associated economic cost. In this study, researchers from Boston Children’s Hospital and Harvard Medical School sought to determine these costs among women aged 40 to 59. Source: UBM Partner…

  • Utilisation of MR spectroscopy and diffusion weighted imaging in predicting and monitoring of breast cancer response to chemotherapy

    Kin Men Leong, Peter Lau, Saadallah Ramadan
    24 Apr 2015 | 2:03 am
    Summary Neoadjuvant chemotherapy (NACT) is the standard treatment option for breast cancer as more data shows that pathologic complete response (pCR) after NACT correlates with improved prognosis. MRI is accepted as the best imaging modality for evaluating the response to NACT in many studies as compared with clinical examination and other imaging modalities. In vivo magnetic resonance spectroscopy (MRS) and diffusion-weighted imaging (DWI) studies have both emerged as potential tools to provide early response indicators based on the changes in the metabolites and the apparent diffusion…

  • Fully automatic evaluation of the corneal endothelium from in vivo confocal microscopy

    Bettina Selig
    26 Apr 2015 | 5:00 am
    Background: Manual and semi-automatic analyses of images, acquired in vivo by confocal microscopy, are often used to determine the quality of corneal endothelium in the human eye. These procedures are highly time consuming. Here, we present two fully automatic methods to analyze and quantify corneal endothelium imaged by in vivo white light slit-scanning confocal microscopy. Methods: In the first approach, endothelial cell density is estimated with the help of spatial frequency analysis. We evaluate published methods, and propose a new, parameter-free method. In the second approach, based on…
  • Eigen-disfigurement model for simulating plausible facial disfigurement after reconstructive surgery

    Juhun Lee
    27 Mar 2015 | 5:00 am
    Background: Patients with facial cancers can experience disfigurement as they may undergo considerable appearance changes from their illness and its treatment. Individuals with difficulties adjusting to facial cancer are concerned about how others perceive and evaluate their appearance. Therefore, it is important to understand how humans perceive disfigured faces. We describe a new strategy that allows simulation of surgically plausible facial disfigurement on a novel face for elucidating the human perception on facial disfigurement.MethodLongitudinal 3D facial images of patients (N = 17)…

  • Homotopic non-local regularized reconstruction from sparse positron emission tomography measurements

    Alexander Wong
    18 Mar 2015 | 5:00 am
    Background: Positron emission tomography scanners collect measurements of a patient’s in vivo radiotracer distribution. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule, and the tomograms must be reconstructed from projections. The reconstruction of tomograms from the acquired PET data is an inverse problem that requires regularization. The use of tightly packed discrete detector rings, although improves signal-to-noise ratio, are often associated with high costs of…

  • Severity of aortic regurgitation assessed by area of vena contracta: a clinical two-dimensional and three-dimensional color Doppler imaging study

    Hirotomo Sato
    4 May 2015 | 5:00 pm
    Background: Quantitation of aortic regurgitation (AR) using two-dimensional (2D) echocardiography, including vena contracta width (VCW) measurement, is still challenging. Three-dimensional (3D) echocardiography can directly measure the vena contracta area (VCA), regardless of the rheological characteristics. We intended to assess the possibility of 3D vena contracta area (3DVCA) as well as 2D vena contracta area (2DVCA) in the assessment of AR severity. Methods: Sixty-one patients with AR [17 female (32.7%); mean age: 74.0 ± 10.1 years] underwent 2D and 3D color Doppler…

  • The left ventricle in aortic stenosis – imaging assessment and clinical implications

    Andreea C¿lin
    28 Apr 2015 | 5:00 pm
    Aortic stenosis has an increasing prevalence in the context of aging population. In these patients non-invasive imaging allows not only the grading of valve stenosis severity, but also the assessment of left ventricular function. These two goals play a key role in clinical decision-making. Although left ventricular ejection fraction is currently the only left ventricular function parameter that guides intervention, current imaging techniques are able to detect early changes in LV structure and function even in asymptomatic patients with significant aortic stenosis and preserved ejection…

    Quirino Ciampi
    21 Apr 2015 | 5:00 am
    Background: Dual imaging stress echocardiography, combining the evaluation of wall motion and coronary flow reserve (CFR) on the left anterior descending artery (LAD), and computed tomography coronary angiography (CTCA) are established techniques for assessing prognosis in chest pain patients. In this study we compared the prognostic value of the two methods in a cohort of patients with chest pain having suspected coronary artery disease (CAD). Methods: A total of 131 patients (76 men; age 68 ± 9 years) with chest pain of unknown origin underwent dipyridamole (up to 0.84 mg/kg over…
  • Left carotid adventitial vasa vasorum signal correlates directly with age and with left carotid intima-media thickness in individuals without atheromatous risk factors

    Maria Arcidiacono
    16 Apr 2015 | 5:00 pm
    ObjectiveThe early identification of the onset of subclinical atheromatosis is essential in reducing the high mortality risk from cardiovascular disease (CVD) worldwide. Although carotid intima-media thickness (cIMT) is the most commonly used early predictor of ongoing atherosclerosis, an experimental model of atherosclerosis, demonstrated that increases in adventitial microvessels (vasa vasorum (VV)) precede endothelial dysfunction. Using the reported accuracy of contrast-enhanced ultrasound (CEU) to measure carotid adventitial VV, this study assessed whether measurements of carotid…

    4 May 2015 | 8:47 am
    Abstract Alcohol use disorder (AUD) is suggested to have polygenic risk factors and also exhibits neurological complications, strongly encouraging a translational study to explore the associations between aggregates of genetic variants and brain function alterations related to alcohol use. In this study, we used a semiblind multivariate approach, parallel independent component analysis with multiple references (pICA-MR) to investigate relationships of genome-wide single nucleotide polymorphisms with alcohol cue-elicited brain activations in 315 heavy drinkers, where pICA-MR assesses multiple…
  • 5-HTTLPR differentially predicts brain network responses to emotional faces

    Patrick M. Fisher, Cheryl L. Grady, Martin K. Madsen, Stephen C. Strother, Gitte M. Knudsen
    30 Apr 2015 | 7:02 am
    Abstract The effects of the 5-HTTLPR polymorphism on neural responses to emotionally salient faces have been studied extensively, focusing on amygdala reactivity and amygdala-prefrontal interactions. Despite compelling evidence that emotional face paradigms engage a distributed network of brain regions involved in emotion, cognitive and visual processing, less is known about 5-HTTLPR effects on broader network responses. To address this, we evaluated 5-HTTLPR differences in the whole-brain response to an emotional faces paradigm including neutral, angry and fearful faces using functional…
  • Neural correlates of personal goal processing during episodic future thinking and mind-wandering: An ALE meta-analysis

    David Stawarczyk, Arnaud D'Argembeau
    30 Apr 2015 | 7:02 am
    Abstract The ability to imagine the future is a complex mental faculty that depends on an ensemble of cognitive processes supported by an extended set of brain regions. Our aim here was to shed light on one key component of future thinking—personal goal processing—and to determine its neural correlates during both directed and spontaneous forms of thoughts. To address this question, we performed separate ALE meta-analyses of neuroimaging studies of episodic future thinking (EFT), mind-wandering, and personal goal processing, and then investigated the commonalities and differences in brain…
  • Power-law dynamics in neuronal and behavioral data introduce spurious correlations

    Natalie Schaworonkow, Duncan A.J. Blythe, Jewgeni Kegeles, Gabriel Curio, Vadim V. Nikulin
    30 Apr 2015 | 7:02 am
    Abstract Relating behavioral and neuroimaging measures is essential to understanding human brain function. Often, this is achieved by computing a correlation between behavioral measures, e.g., reaction times, and neurophysiological recordings, e.g., prestimulus EEG alpha-power, on a single-trial-basis. This approach treats individual trials as independent measurements and ignores the fact that data are acquired in a temporal order. It has already been shown that behavioral measures as well as neurophysiological recordings display power-law dynamics, which implies that trials are not in fact…
  • Sub-hubs of baseline functional brain networks are related to early improvement following two-week pharmacological therapy for major depressive disorder

    Yuedi Shen, Jiashu Yao, Xueyan Jiang, Lei Zhang, Luoyi Xu, Rui Feng, Liqiang Cai, Jing Liu, Jinhui Wang, Wei Chen
    30 Apr 2015 | 7:02 am
    Abstract Accumulating evidence suggests that early improvement after two-week antidepressant treatment is predictive of later outcomes of patients with major depressive disorder (MDD); however, whether this early improvement is associated with baseline neural architecture remains largely unknown. Utilizing resting-state functional MRI data and graph-based network approaches, this study calculated voxel-wise degree centrality maps for 24 MDD patients at baseline and linked them with changes in the Hamilton Rating Scale for Depression (HAMD) scores after two weeks of medication. Six clusters…

  • Clinical Outcomes of Computed Tomography-Based Volumetric Brachytherapy Planning for Cervical Cancer

    Daniel R. Simpson, Daniel J. Scanderbeg, Ruben Carmona, Riley M. McMurtrie, John Einck, Loren K. Mell, Michael T. McHale, Cheryl C. Saenz, Steven C. Plaxe, Terry Harrison, Arno J. Mundt, Catheryn M. Yashar
    3 May 2015 | 5:00 pm
    Image-guided brachytherapy (IGBT) has been adopted by multiple centers in recent years for treatment of cervical cancer. Clinical outcomes are promising with favorable results compared to conventional techniques. Previously reported studies have utilized primarily MRI-based treatment planning. We report clinical outcomes of a novel hybrid computed tomography-based IGBT technique. At two years, the local control was excellent with low rates of treatment toxicity. Further follow-up is needed to evaluate the long-term outcomes of this technique.

  • Combined modality management of retroperitoneal sarcomas: a single institution series of 121 patients

    Andrew J. Bishop, Gunar K. Zagars, Keila E. Torres, Kelly K. Hunt, Janice N. Cormier, Barry W. Feig, B. Ashleigh Guadagnolo
    2 May 2015 | 5:00 pm
    Retroperitoneal sarcomas have high rates of local relapse with surgery alone. Therefore, we reviewed our experience of treating patients with retroperitoneal sarcomas with combined surgery and radiation therapy to evaluate local control, survival outcomes, and complication rates. Intra-abdominal control continues to be poor despite aggressive multimodality therapy. Furthermore, given the complications associated with postoperative radiation therapy, we recommend that preoperative radiation therapy is the preferred strategy when combined modality therapy is recommended.

    Background: Radiation-induced bronchiolitis obliterans organizing pneumonia (BOOP) syndrome is a rarely observed phenomenon characterized by infiltration of the lungs outside of the radiation field, differentiating it from radiation pneumonitis (RP).The risk factors for radiation-induced BOOP (RT-BOOP) remain unclear and controversial. We retrospectively analyzed the incidence and risk factors for RT-BOOP associated with radiation therapy (RT) after breast conserving surgery (BCS) and post-mastectomy radiation therapy (PMRT).Methods and materialsWe analyzed 1,176 breast cancer patients…
  • Targeting IAP proteins in combination with radiotherapy

    25 Apr 2015 | 5:00 pm
    The efficacy of radiotherapy critically depends on the activation of intrinsic cell death programs in cancer cells. This implies that evasion of cell death, a hallmark of human cancers, can contribute to radioresistance. Therefore, novel strategies to reactivate cell death programs in cancer cells are required in order to overcome resistance to radiotherapy. Since Inhibitor of Apoptosis (IAP) proteins are expressed at high levels in multiple cancers and block cell death induction at a central point, therapeutic targeting of IAP proteins represents a promising approach to potentiate the…
  • Comparison of radiation regimens in the treatment of Glioblastoma multiforme: results from a single institution

    Background: The optimal fractionation schedule of radiotherapy (RT) for Glioblastoma multiforme (GBM) is yet to be determined. We aim to compare different fractionation regimens and identify prognostic factors to better tailor RT for newly diagnosed GBM patients. Methods: All data for patients who underwent surgery for GBM between January 2005 and December 2012 were compiled. Clinical information was collected using patient charts and government registry. Cox analysis was used to identify variables affecting survival and treatment outcome. Results: The median follow-up time was 13.2 months.

    At times life seems to move faster than life itself. In order to take more out of your day you shift to faster cars and chose best possible flights to get more out of the day. When you are rushing through, you just are focussed on targets and speed. Targets keep getting steeper and speed is never fast enough.One day I decided to make it point to go slower. I deliberately took a wrong turn and felt the joy of being in new route where I didn't know where it would lead. I had to focus on surrounding to get the route back towards my destination. I noticed more than usual as my awareness was…
