    CHICAGO — While changes, and challenges, in the U.S. health care delivery system have typically been attributed to the Affordable Care Act, many of these changes would have happened regardless, said Thomas W. Greeson, JD, at RSNA 2014. The ACA accelerated this activity, Greeson noted, but it has long been a suspicion that the contributor, or possibly the culprit, of the high health care cost is the fee-for-service system.

  • Where Does Your State Stand on Breast Density Notification Laws?

    Alessandra Simmons
    17 Mar 2015 | 7:00 am
    Breast density notification laws have been put into effect in 21 states. A breast density notification law requires that physicians notify women who have undergone mammography and were found to have dense breast tissue. The intent of such a law was to give women the necessary information to decide on further action if they had dense breast tissue. Dense breast tissue makes it harder to identify cancer on a mammogram and may also be associated with an increased risk of breast cancer, according to the American College of Radiology (ACR).  Learn more about Breast Density Notification Laws and…

  • Sweeping prostate cancer review upends widely held belief on radiation after surgery

    25 Mar 2015 | 2:42 am
    Important news for men receiving treatment for prostate cancer: Two new studies from the University of Virginia School of Medicine have upended the widely held view that it's best to delay radiation treatment as long as possible after the removal of the prostate in order to prevent unwanted side effects. "The common teaching has been, without clear evidence, that urinary incontinence and erectile function are worse when radiation is delivered earlier rather than later, but we didn't see any protective effect of delayed radiation compared to earlier radiation," said radiation oncologist…

  • Initial experience using the rigid forceps technique to remove wall-embedded IVC filters

    Allan Avery, Maximilian Stephens, Kendal Redmond, John Harper
    6 Mar 2015 | 5:04 am
    Abstract IntroductionSeverely tilted and embedded inferior vena cava (IVC) filters remain the most challenging IVC filters to remove. Heavy endothelialisation over the filter hook can prevent engagement with standard snare and cone recovery techniques. The rigid forceps technique offers a way to dissect the endothelial cap and reliably retrieve severely tilted and embedded filters. By developing this technique, failed IVC retrieval rates can be significantly reduced and the optimum safety profile offered by temporary filters can be achieved. We present our initial experience with the rigid…

  • Use of implanted gold fiducial markers with MV-CBCT image-guided IMRT for pancreatic tumours

    Matthew Packard, Olivier Gayou, Krishna Gurram, Brandon Weiss, Shyam Thakkar, Alexander Kirichenko
    5 Mar 2015 | 2:49 am
    Abstract IntroductionVisualisation of soft tissues such as pancreatic tumours by mega-voltage cone beam CT (MV-CBCT) is frequently difficult and daily localisation is often based on more easily seen adjacent bony anatomy. Fiducial markers implanted into pancreatic tumours serve as surrogates for tumour position and may more accurately represent absolute tumour position. Differences in daily shifts based on alignment to implanted fiducial markers vs. alignment to adjacent bony anatomy were compared. MethodsGold fiducial markers were placed into the pancreatic tumour under endoscopic ultrasound…

  • 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…

This study aimed to report the results of magnetic resonance imaging (MRI) study in the patients in whom bone injury was not radiographically detected around the wrist joint, and the PQ was sonographically swollen following acute trauma. Methods: We evaluated sonographically the PQ of 55 patients who showed normal radiographs following acute trauma. The sonographic appearance of the PQ was checked on both longitudinal and transverse…
  • The accuracy of radiology speech recognition reports in a multilingual South African teaching hospital

    Jacqueline du Toit
    3 Mar 2015 | 4:00 pm
    Background: Speech recognition (SR) technology, the process whereby spoken words are converted to digital text, has been used in radiology reporting since 1981. It was initially anticipated that SR would dominate radiology reporting, with claims of up to 99% accuracy, reduced turnaround times and significant cost savings. However, expectations have not yet been realised. The limited data available suggest SR reports have significantly higher levels of inaccuracy than traditional dictation transcription (DT) reports, as well as incurring greater aggregate costs.There has been little work on…

    28 Mar 2015 | 9:38 am
    Abstract Multisite neuroimaging studies can facilitate the investigation of brain-related changes in many contexts, including patient groups that are relatively rare in the general population. Though multisite studies have characterized the reliability of brain activation during working memory and motor functional magnetic resonance imaging tasks, emotion processing tasks, pertinent to many clinical populations, remain less explored. A traveling participants study was conducted with eight healthy volunteers scanned twice on consecutive days at each of the eight North American Longitudinal…
  • Sensation-to-cognition cortical streams in attention-deficit/hyperactivity disorder

    Susana Carmona, Elseline Hoekzema, Francisco X. Castellanos, David García-García, Agustín Lage-Castellanos, Koene R.A. Van Dijk, Francisco J. Navas-Sánchez, Kenia Martínez, Manuel Desco, Jorge Sepulcre
    28 Mar 2015 | 9:31 am
    Abstract We sought to determine whether functional connectivity streams that link sensory, attentional, and higher-order cognitive circuits are atypical in attention-deficit/hyperactivity disorder (ADHD). We applied a graph-theory method to the resting-state functional magnetic resonance imaging data of 120 children with ADHD and 120 age-matched typically developing children (TDC). Starting in unimodal primary cortex—visual, auditory, and somatosensory—we used stepwise functional connectivity to calculate functional connectivity paths at discrete numbers of relay stations (or link-step…
  • Human pulvinar functional organization and connectivity

    Daniel S. Barron, Simon B. Eickhoff, Mareike Clos, Peter T. Fox
    28 Mar 2015 | 9:26 am
    Abstract The human pulvinar is the largest thalamic area in terms of size and cortical connectivity. Although much is known about regional pulvinar structural anatomy, relatively little is known about pulvinar functional anatomy in humans. Cooccurrence of experimentally induced brain activity is a traditional metric used to establish interregional brain connectivity and forms the foundation of functional neuroimaging connectivity analyses. Because functional neuroimaging studies report task-related coactivations within a standardized space, meta-analysis of many whole-brain studies can define…
  • Differential patterns of functional and structural plasticity within and between inferior frontal gyri support training-induced improvements in inhibitory control proficiency

    Camille F. Chavan, Michael Mouthon, Bogdan Draganski, Wietske van der Zwaag, Lucas Spierer
    19 Mar 2015 | 9:32 pm
    Abstract Ample evidence indicates that inhibitory control (IC), a key executive component referring to the ability to suppress cognitive or motor processes, relies on a right-lateralized fronto-basal brain network. However, whether and how IC can be improved with training and the underlying neuroplastic mechanisms remains largely unresolved. We used functional and structural magnetic resonance imaging to measure the effects of 2 weeks of training with a Go/NoGo task specifically designed to improve frontal top-down IC mechanisms. The training-induced behavioral improvements were accompanied…

  • Presence of a high-flow-mediated constriction phenomenon prior to flow-mediated dilation in normal weight, overweight, and obese children and adolescents

    Joseph D. Ostrem, Nicholas Evanoff, Aaron S. Kelly, Donald R. Dengel
    20 Mar 2015 | 6:24 am
    ABSTRACT PurposeWhen assessing vasomotor endothelial function by reactive hyperemia, the brachial artery, in some individuals, constricts immediately before beginning to dilate following cuff release. We call this response high-flow-mediated constriction (H-FMC). The aim of this study was to describe the rate of the H-FMC during reactive hyperemia in children and adolescents throughout a range of body mass index (BMI) values, and to investigate differences in flow-mediated dilation (FMD), cardiovascular, and anthropometric measures between subjects with and without H-FMC. MethodsFMD was…

    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…

    Background: To investigate the incidence and risk of severe late toxicity with concurrent chemoradiotherapy (CCRT) in nasopharyngeal carcinoma patients. Methods: Eligible studies included prospective randomized controlled trials (RCTs) evaluating CCRT versus radiotherapy alone in patients with nasopharyngeal carcinoma and in which data on severe late toxicities were available. Random effects or fixed effect models were applied to obtain the summary incidence, relative risks (RRs) and 95% confidence intervals (CIs). Results: Five RCTs with 1102 patients with NPC were included in this analysis.

    “Time” is the most valuable asset we all have. Why waste it in reacting to other’s actions?This is something that I keep reminding myself. Often while driving down the Delhi city, I notice people fighting their heart out over small scratch on their cars. On other hand, usually if someone by mistake hits my car, I usually remind myself that people are more important than things and I just raise my hand to show my displeasure and I drive on. As I believe my time in life is better spent constructively rather than angrily reacting.That has been the guiding principle in most of my life,…
  • Radiologists are Rodney Dangerfields of medicine-Article Reports

    25 Mar 2015 | 11:05 pm
    Special Article in  LAS VEGAS REVIEW-JOURNAL writes this interesting piece about role of radiologists in medical practice. Article says "Radiologists are a bit like the Rodney Dangerfields of medicine — they just can’t get any respect from the public. Television and films have a seeming love affair with surgeons. Even coroners and pathologists get more attention from Hollywood."However, Dr Steinberg disagrees to this practice of ignoring the contribution of radiologists towards healthcare by public in general.  For those of you who don't know, Rodney Dangerfield was an…
