Patients released from hospital much faster without increased costs or risk of missed diagnosis Incorporating coronary CT angiography (CCTA) into the initial evaluation of low-risk patients coming to hospital emergency departments (EDs) with chest pain appears to reduce the time patients spend in the hospital without incurring additional costs or exposing patients to significant risks. The report of a study conducted at nine U.S. hospitals appears in the July 26 New England Journal of...

Advances in diagnostic imaging have benefited children with otolaryngologic disease, allowing shorter hospital stays, fewer invasive procedures, more targeted surgical procedures, and earlier and more precise diagnoses. However, despite improved technology, concerns about exposure of children to ionizing radiation have recently come to the forefront, according to a commentary in the July 2012 issue of Otolaryngology—Head and Neck Surgery. Children have more radiosensitive body...

A new study of 1,400 Medicare-aged patients reinforces CT colonography as a screening tool for colon cancer, adding to the continued debate over Medicare coverage of the procedure. In 2009, the Centers for Medicare and Medicaid Services indicated that CT colonography would not be covered, in part, because outcomes data specific to the Medicare population was not available. "Our study answers several of the questions Medicare asked about this procedure," said Brooks Cash, MD, one of the...

Research finds technology combining molecular imaging and CT can cut down on patient dose by limiting the number of CT scans per imaging study Molecular imaging is effective for providing information about disease processes, and today's hybrid imaging systems have additional computed tomography (CT) technology on board for alignment and imaging structures. While this addition increases the amount of radiation dose a patient receives, research presented at the Society of Nuclear...

New molecular imaging technique compensates for breathing and heartbeat to deliver highest-quality images of the heart A development in 4D image reconstruction compensates for blurring caused by the beating of the heart, say researchers at the Society of Nuclear Medicine's 59th Annual Meeting. The new method provides sharper-than-ever images of cardiac function to help pinpoint heart defects for better diagnoses and treatment. Cardiovascular disease is the number one killer across the...
