Controversy erupts over CNN article on board 'recalls' January 16, 2012 -- Reactions have been mixed to a CNN article published online last week that describes doctors' widespread use of "recalls" -- banks of test information gathered by residents who have memorized questions -- on the exam they take to become board-certified in radiology.
CORE 64: Calcium predicts CCTA effectiveness January 16, 2012 -- A new analysis of coronary CT angiography (CCTA) demonstrates the need to obtain coronary calcium scores before scanning patients with suspected obstructive disease, while also underscoring the need for pretest calculation of disease probability, researchers report in the Journal of the American College of Cardiology.
Couch attenuation undermines radiotherapy plan quality January 16, 2012 -- Treatment couches used to support a patient during intensity-modulated radiotherapy and arc therapy can unknowingly lead to an unacceptable reduction in dose to target structures. Rail placement can also affect the dose delivered.
BSGI helps detect more breast cancer, alter treatment January 13, 2012 -- Breast-specific gamma imaging (BSGI) confirmed mammography, ultrasound, and MRI results in 55% of patients and identified additional malignant lesions, clarified ambiguous findings, or significantly changed patient management in 20% of cases, according to a study from California researchers.
ABR policy on exam recalls: Please read carefully January 13, 2012 -- There has been intense debate regarding the American Board of Radiology's (ABR) recent policy changes on sharing exam items, but these changes go to the heart of maintaining professionalism in radiology, says Dr. Jannette Collins, chair of radiology at the University of Cincinnati College of Medicine, in this editorial.
U.S. may allow digital x-ray to monitor black lung in miners January 12, 2012 -- A new proposal from the U.S. Department of Health and Human Services would allow lung scans of coal miners to be performed with digital x-ray systems in addition to traditional film-based radiography, according to a proposed rule appearing January 9 in the Federal Register.
