CT dose reporting challenged by current indicators January 27, 2012 -- Capturing CT radiation dose information is a hot topic, but it's complicated by the incomplete methods used for measuring, determining, and calculating dose, said Anthony Seibert, PhD, of the University of California, Davis. Seibert discussed dose capture in a January 25 webinar hosted by the Society for Imaging Informatics in Medicine.
Study shows CR exposure creep can be slowed, but is hard to stop January 27, 2012 -- The long-suspected existence of exposure creep has been documented in a long-term study of computed radiography (CR) practices at an Australian teaching hospital. The study highlights the need for uniform exposure standards for CR systems manufactured by different vendors.
Despite speed bump, iPad up for task of assessing tuberculosis January 26, 2012 -- Despite experiencing noticeably slower workflow, radiologists evaluating patients for tuberculosis reported similar diagnostic performance regardless of whether they read images from Apple's iPad or a traditional LCD monitor, according to research from the University of Maryland.
Follow-up protocol performs well in CT lung screening January 26, 2012 -- Researchers reported good results with a protocol for working up patients with nodules found on CT lung screening, according to research in the February American Journal of Roentgenology. The algorithm produced low false-positive rates, and could make the establishment of large-scale CT screening programs more feasible.
Prostate brachytherapy reduces death rates of high-risk men January 26, 2012 -- Prostate brachytherapy for high-risk prostate cancer patients has historically been considered a less effective treatment, but a new study of almost 13,000 men published online January 23 in the International Journal of Radiation Oncology, Biology, Physics suggests otherwise.
LCIS lesions found on biopsy should be removed January 25, 2012 -- Lobular carcinoma in situ (LCIS) is a relatively rare high risk marker for breast cancer, but LCIS lesions found on core needle biopsy should be removed, according to a new study published in the February issue of the American Journal of Roentgenology.
BSGI equals MRI as an adjunct in breast cancer cases January 25, 2012 -- Researchers in Oregon have concluded that breast-specific gamma imaging (BSGI) is equivalent to MRI as an adjunct imaging modality for diagnosing breast cancer. BSGI may be particularly useful in evaluating women at high risk for cancer, or those with dense breasts.
Study questions use of MRI for neuropathy patients January 25, 2012 -- Researchers at the University of Michigan have found that nearly one-quarter of patients with neuropathy diagnoses undergo MRI scans, while only 1% of patients receive far cheaper glucose tolerance tests, according to a study published January 23 in the Archives of Internal Medicine.
Medicare fraud charges filed against 5 Pa. cardiologists January 24, 2012 -- A whistleblower suit filed this week in a U.S. District Court in Pennsylvania alleges that cardiologists from two medical practices in the state defrauded Medicare by participating in illegal kickback schemes and performing unnecessary cardiac, vascular, and interventional procedures between 2001 and 2005.
Pre-op MRI changes surgical plans for prostate cancer patients January 24, 2012 -- The additional information provided by preoperative prostate MRI influenced the extent of surgery in 27% of patients who underwent robotic-assisted laparoscopic prostatectomy, according to a new study published online January 24 in Radiology.
