MONDAY, July 26 (HealthDay News) -- Prophylactic breast irradiation may decrease the rate of gynecomastia in prostate cancer patients receiving bicalutamide; however, with a relatively low number of men significantly bothered by this issue, not all patients need this prophylaxis, according to research published in the August issue of The Journal of Urology.
Pelvic Radiation in Girls Tied to Higher Stillbirth Risk
FRIDAY, July 23 (HealthDay News) -- Female survivors of childhood cancer treated with pelvic radiation have a much higher risk of stillbirth and neonatal death in their offspring than do females who did not get radiation, but there is no increased risk for male survivors who received gonadal radiation, according to research published online July 23 in the The Lancet.
Knee OA Can Be Predicted From MRI Findings Decade Earlier
THURSDAY, July 22 (HealthDay News) -- The type of subacute knee injury seen on magnetic resonance imaging (MRI) at initial examination can predict the features of knee osteoarthritis (OA) likely to develop in the years ahead, according to a study published online June 29 in Radiology.
5.2 Percent of Residency Applicant Essays Plagiarized
TUESDAY, July 20 (HealthDay News) -- About 5 percent of the application essays to residency programs -- often referred to as the personal statement -- contain plagiarized material, according to research published in the July 20 issue of the Annals of Internal Medicine.
Serial CT Angiography Detects Plaque Morphology Changes
FRIDAY, July 16 (HealthDay News) -- Evaluation of coronary plaques with serial computed tomography angiography (CTA) allows interval changes in plaque morphology to be assessed, and statin treatment is linked to decreases in markers associated with plaque instability, according to a study in the July issue of the Journal of the American College of Cardiology: Cardiovascular Imaging.
Myocardial Perfusion Imaging, eGFR Aid in Risk Stratification
FRIDAY, July 16 (HealthDay News) -- In patients with and without diabetes, myocardial perfusion imaging (MPI) and estimated glomerular filtration rate (eGFR) are valuable for risk stratification, and underlying chronic kidney disease (CKD) in diabetes patients is linked to an increased risk of cardiac death, according to research published in the July issue of the Journal of the American College of Cardiology: Cardiovascular Imaging.
'Ghosts' After Heart Device Removal Linked to Infection
FRIDAY, July 16 (HealthDay News) -- The presence of "ghosts" -- or intracardiac masses noted on echocardiography after device removal -- suggests device infection and may be associated with cardiac device-related infective endocarditis (CDRIE); these ghosts are present in 8 percent of patients after percutaneous device removal, according to research published in the July issue of the Journal of the American College of Cardiology: Cardiovascular Imaging.
Algorithm for Quantification of Stenosis Severity Feasible
THURSDAY, July 15 (HealthDay News) -- Quantitative coronary computed tomography angiography (QCCTA) has good correlations with quantitative coronary angiography (QCA) for quantification of stenosis severity in patients with known or suspected coronary artery disease, with QCCTA showing better positive predictive value than visual analysis, according to research published in the July issue of the Journal of the American College of Cardiology: Cardiovascular Imaging.
BMIPP Data Improve Acute Coronary Syndrome Diagnosis
THURSDAY, July 15 (HealthDay News) -- Use of β-methyl-p-[123I]-iodophenyl-pentadecanoic acid (BMIPP) data in addition to initially available information can help with the early diagnosis of acute coronary syndromes (ACS), according to research published in the July 20 issue of the Journal of the American College of Cardiology.
Breast Density Not a Risk Factor for BRCA Carriers
MONDAY, July 12 (HealthDay News) -- Although breast density is a risk factor for breast cancer in the general population, it does not appear to increase risk in women with BRCA mutations, according to research published online July 12 in the Journal of Clinical Oncology.
Diffusion-Weighted Imaging Superior for Stroke Diagnosis
MONDAY, July 12 (HealthDay News) -- Diffusion-weighted imaging (DWI) is accurate and appears to be more useful than noncontrast computed tomography (CT) for diagnosing acute ischemic stroke within 12 hours after symptoms appear; however, there is not enough evidence to support or refute the efficacy of perfusion-weighted imaging (PWI) in diagnosing acute ischemic stroke, according to an analysis published in the July 13 issue of Neurology.
Cardiac Imaging Confers Substantial Radiation Exposure
