MRI has been shown to be more effective than mammography at identifying suspicious areas in the breast, but it can't always distinguish between malignant and benign lesions, which may result in further testing and false-positive results. Researchers from Warren Alpert Medical School of Brown University in Providence, RI, explored whether having prior MR images for [...]
February 2, 2011 -- NEW YORK (Reuters Health) - Low-dose noncontrast CT isn't as effective as standard-dose CT in diagnosis of kidney stones, particularly small ones, but this reduced radiation approach may still have advantages over other imaging tools. "Low-dose protocol CT for kidney stone detection is more sensitive compared to plain abdominal film or [...]
In a U.K. study evaluating dry mouth toxicities, intensity-modulated radiation therapy (IMRT) proved to be far less debilitating for cancer patients than conventional radiation therapy. Results were published online January 12 in The Lancet Oncology. The randomized phase III PARSPORT trial included six U.K. cancer treatment centers participating from 2003 through 2007. The study was [...]
January 12, 2011 -- NEW YORK (Reuters Health) - Low-dose CT coronary angiography (CTCA) could be sparing more patients from invasive angiography, a new report from Switzerland suggests. "We should stop sending patients with low pretest-probability into the cath lab for invasive coronary angiography to rule out coronary artery disease (CAD)," Dr. Philipp A. Kaufmann [...]
January 13, 2011 -- Despite American Cancer Society guidelines recommending that women at high risk for breast cancer undergo MRI screening in addition to regular mammography, only 14% of these women are getting the scans, according to researchers from the University of Colorado. John Brinton, of the University of Colorado, Denver, and colleagues at Invision [...]

OAK BROOK, Ill. – By combining optical and x-ray imaging, radiologists may be better able to distinguish cancer from benign lesions in the breast, according to a new study published in the online edition and January issue [...]
The National Cancer Institute (NCI) released initial results from a large-scale test of screening methods to reduce deaths from lung cancer by detecting cancers at relatively early stages. The National Lung Screening Trial (NLST), a randomized national trial involving more than 53,000 current and former heavy smokers ages 55 to 74, compared the effects of [...]
