Knee MRI prices can vary almost 8-fold across the U.S. May 6, 2015 -- The price of an outpatient noncontrast MRI scan of the knee can vary across the U.S. by almost eightfold, according to a new study in the May issue of the Journal of the American College of Radiology. The finding sheds light on an increasingly consumer-driven healthcare environment, researchers from the Mayo Clinic in Rochester, MN, wrote.
New CT-based liver segmentation tool proves fast and accurate May 6, 2015 -- Liver segmentation, used to obtain liver volumes when planning for major interventions, can be automated without loss of accuracy compared to manual measurements, cutting procedure time by more than half, according to a new study in Academic Radiology.
Gadolinium contrast retention raises new safety questions May 5, 2015 -- A new study by Japanese researchers published on May 5 in Radiology confirms previous findings that traces of gadolinium contrast remain in the brains of people who receive contrast-enhanced MRI scans. The results are raising new questions about the safety of gadolinium-based contrast, such as whether the deposits are harmful.
Mobile App Spotlight: CT Anatomy May 5, 2015 -- AuntMinnie.com presents the next article in an ongoing series highlighting notable mobile apps in radiology. In this installment, we take a look at CT Anatomy, an iOS app that offers a cross-sectional guide of normal anatomy as seen on CT.
Nonradiologists get most of Medicare imaging payments May 4, 2015 -- More than 50% of Medicare payments for diagnostic imaging services in the U.S. are made to nonradiologists, according to a study published in the May issue of the American Journal of Roentgenology. In fact, Medicare payments to nonradiologists for diagnostic imaging exceed those to radiologists in almost 60% of states.
CT reveals cardioembolic stroke that echo misses May 1, 2015 -- Echocardiography may be the de facto gold standard for cardiac evaluation of patients suspected of having cardioembolic stroke, but it isn't necessarily the best modality. A new study from Saudi Arabia used CT to discover several thrombi that echo had missed, along with other conditions.
No need for CT: Contrast US can follow up solid-organ injuries April 30, 2015 -- Contrast-enhanced ultrasound (CEUS) can be used in favor of CT for following up solid-organ injuries in children and young adults, avoiding unnecessary radiation exposure in this vulnerable population, according to researchers from King's College Hospital in the U.K. who reported their findings from a large retrospective study.
No cost difference between CTC, colonoscopy in elderly April 30, 2015 -- A new analysis of Medicare data has found that after adjusting for patient demographic factors, costs are pretty much the same in the year following an initial screening exam for colorectal cancer, regardless of whether CT colonography (CTC) or optical colonoscopy is used, according to a report in Academic Radiology.
Safety-net hospital lifts the lid on child abuse April 29, 2015 -- Fresh data about suspected cases of abuse show that about a quarter of children evaluated at an inner city hospital by means of a skeletal survey with radiography were found to be the victims of abuse. Furthermore, of the abused children, around 39% had skeletal trauma and 61% did not.
Should women over 75 be screened for breast cancer? April 29, 2015 -- New guidelines proposed last week on mammography screening claim that evidence is insufficient to recommend screening for women 75 and older. But if such women are healthy and without other disease, why shouldn't screening continue? Dr. Stamatia Destounis believes it should.
fMRI finds women recover more slowly from concussions than men April 28, 2015 -- A new study published online April 28 in Radiology indicates that women have a more difficult time recovering from concussions than men, based on brain activation patterns seen on functional MRI (fMRI) during working memory tasks. The results hint that more aggressive treatment could be warranted after head injuries in women.
Congenital heart disease detected less often in rural areas April 28, 2015 -- Ultrasound may be doing a better job overall of diagnosing critical congenital heart disease prenatally, but that's not necessarily the case in poorer and more rural communities, according to research presented on Monday at the Pediatric Academic Societies annual meeting in San Diego.
ARRS: 6 reasons to be optimistic about radiology April 27, 2015 -- Radiologists love to complain about the challenges they face, including declining reimbursements, a tight job market, and increased workload. But there are at least six good reasons to be optimistic about the specialty, according to a presentation at the American Roentgen Ray Society (ARRS) annual meeting in Toronto.
Motion-tracking MRI gives new insight into stroke risk April 27, 2015 -- Using a novel motion-tracking MRI technique, researchers from Johns Hopkins University have uncovered new evidence that reduced function in the left atrium of the heart may be a sign of increased stroke risk in patients with or without atrial fibrillation.
Bedside ultrasound can diagnose acute shoulder dislocation April 24, 2015 -- Patients presenting to the emergency department with acute shoulder pain typically receive an x-ray exam. However, ultrasound can provide equivalent performance -- often in less time and without the ionizing radiation -- for diagnosing shoulder dislocation, according to researchers from the University of California, Irvine.
