Wayne Forrest[email protected]MRIMRI shows less gray matter in drug-using women than menWomen 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.July 13, 2015Nuclear MedicineBrain SPECT shows improvement after cocaine users abstainDysfunction 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.July 9, 2015MRIMRI ties small brain lesions to risk of stroke, deathAsymptomatic 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.July 6, 2015MRIAnimal study raises concern over gadolinium contrast agentA new animal study published online June 22 in Investigative Radiology has linked one class of gadolinium-based contrast agents to increased deposits of the element in the brains of rats, highlighting recent safety concerns about the use of the MRI contrast medium.June 29, 2015MRIDTI-MRI links maternal obesity to newborn brain growthInfants born to mothers who are obese display altered brain development, according to a new study in which diffusion-tensor MRI (DTI-MRI) showed reduced white-matter integrity in regions of the infants' brains that are associated with cognitive function.June 25, 2015Nuclear MedicineProposal would dissolve ABNM, fold functions into ABRIn the face of an increasingly difficult job market for nuclear medicine physicians, a proposal has been floated to dissolve the American Board of Nuclear Medicine (ABNM) and fold its functions into the American Board of Radiology (ABR). The combined organization would oversee a new, broader certification for imaging specialists.June 24, 2015MRIAuntMinnie.com MRI InsiderJune 22, 2015Nuclear MedicineFlorbetaben-PET finds more beta-amyloid plaquesNew research indicates that PET imaging with the radiotracer florbetaben can detect a form of beta-amyloid plaque that develops early in the brain. The findings could possibly lead to the earlier detection of Alzheimer's disease, as well as new clinical indications for florbetaben.June 21, 2015Molecular ImagingAuntMinnie.com Molecular Imaging InsiderJune 17, 2015MRIDTI-MRI sheds light on concussion symptomsResearchers from the University of Pittsburgh Medical Center have uncovered distinct injury patterns in the brain using diffusion-tensor MRI (DTI-MRI) in people with concussion-related depression or anxiety.
