ACRIN: Digital mammography delivers less radiation than analog
January 21, 2010 -- Although the differences between full-field digital mammography and film-screen mammography in terms of compression force are small, FFDM delivers much less radiation than analog mammography, according to a study to be published in the February issue of the American Journal of Roentgenology.
Italian researchers cut gadolinium dose -- as well as NSF risk
January 21, 2010 -- A half dose of a commercially available MRI contrast agent works as well as a full dose in patients with acute myocardial infarction, according to Italian researchers. The findings show it's possible to achieve shorter imaging times while protecting renally impaired cardiac patients at risk for nephrogenic systemic fibrosis (NSF).
Imaging shows that even mild COPD reduces cardiac efficiency
January 20, 2010 -- Even mild cases of chronic obstructive pulmonary disease (COPD) have serious effects on the heart and blood circulation, according to a study to be published Thursday in the New England Journal of Medicine. The analysis found that the same problems long associated with severe disease are also present in milder cases.
Cochrane: Doppler US improves outcomes in high-risk pregnancies
January 20, 2010 -- The use of Doppler ultrasound to monitor fetal health during high-risk pregnancies improves outcomes by decreasing the number of both cesarean sections and perinatal deaths, according to a new meta-analysis from the Cochrane Collaboration.
New guidelines issued for treatment of brain metastases
January 20, 2010 -- The most effective treatment for patients with newly diagnosed brain metastases is either surgical resection or stereotactic radiosurgery followed by whole-brain radiation, according to new evidence-based guidelines issued by the American Association of Neurological Surgeons and the Congress of Neurological Surgeons in the Journal of Neuro-Oncology.
Radiology mobilizes to help Haiti in wake of devastating earthquake
January 19, 2010 -- University of Virginia radiologist Dr. Gia Deangelis came perilously close to being one of the casualties in last week's massive earthquake in Haiti. Deangelis was supposed to be in Port-au-Prince on January 12, the day the quake struck, and has now returned to help with the relief effort.
Experience counts when reading contrast ultrasound liver images
January 19, 2010 -- Radiologists with experience reading contrast-enhanced ultrasound images have the upper hand over neophytes in characterizing malignant liver tumors, according to research published in the January issue of the Journal of Ultrasound in Medicine.
