Shortened breast MR protocol works just as well as full July 15, 2015 -- Using an abbreviated screening protocol for contrast-enhanced breast MR works just as well in terms of specificity and sensitivity as a full protocol, according to a new study published online in Academic Radiology.
MRI shows less gray matter in drug-using women than men July 14, 2015 -- Women with long-term use of stimulant drugs have significantly less gray-matter volume in several brain areas than healthy women and even men who abused drugs more severely, according to a study published online July 14 in Radiology.
JACR: Radiologists order CT, MR exams appropriately July 13, 2015 -- When it comes to abdominal CT and MRI, radiologists are making good use of all available prior imaging before recommending additional exams, and they aren't ordering many unnecessary exams, according to a new study published in the Journal of the American College of Radiology.
Brain SPECT shows improvement after cocaine users abstain July 10, 2015 -- Dysfunction in the prefrontal cortex region of the brain caused by excessive cocaine use may be reversed to some degree after more than one month of abstinence, researchers from Uruguay have found. Their findings are promising news for rehabilitation efforts, but the group cautioned that some brain dysfunction does appear to remain.
Radiology averts cuts in proposed 2016 MPFS July 9, 2015 -- Radiology has dodged a bullet in the proposed rule for the 2016 Medicare Physician Fee Schedule (MPFS) released on July 8 by the U.S. Centers for Medicare and Medicaid Services, receiving no payment increases or decreases.
Dutch researchers launch DENSE breast MR trial July 9, 2015 -- It's well-known that mammography is less effective in women with dense breast tissue. But what hasn't been established is which supplemental modality is best for these women. Dutch researchers have launched a trial to study the use of MRI in addition to mammography for screening women with dense breast tissue.
A (myocardial) bridge too far: CT vs. IVUS in the heart July 8, 2015 -- Multidetector-row CT should be considered the noninvasive gold standard when evaluating myocardial bridge abnormalities, owing to its anatomic accuracy. But there are important things CT doesn't see that intravascular ultrasound (IVUS) does, according to new research from Stanford University.
Coronary calcium CT scans predict mortality July 7, 2015 -- A simple coronary calcium CT scan can be used to predict death in asymptomatic individuals for as long as 15 years after the scan, according to a new study of nearly 10,000 people, published in the July 7 issue of the Annals of Internal Medicine.
MRI ties small brain lesions to risk of stroke, death July 7, 2015 -- Asymptomatic patients may have triple the risk of stroke and death if they have brain lesions smaller than 3 mm on 1.5-tesla MRI, a new study concludes. Furthermore, if the patients also have lesions 3 mm or larger, they may face an eightfold increase in stroke risk.
New study again questions screening mammography July 6, 2015 -- A new research study published online July 6 in JAMA Internal Medicine is again questioning the effectiveness of widespread breast screening. Mammography screening of the general U.S. population mostly just produces overdiagnosis, with no measurable effect on mortality, according to the researchers.
