Medical imaging overutilization--a growing concern in the U.S.--exposes patients to unnecessary radiation, while also adding to rising healthcare costs, according to a study published online Aug. 24 in Radiology. In an interview, William R. Hendee, PhD, lead author, reviewed various methods by which medical imaging could be curtailed.

The medical imaging informatics section of the Medical Imaging and Technology Alliance (MITA) has issued a whitepaper to policymakers, suggesting that the integration of medical images into patient records should be considered for inclusion in the meaningful use criteria as of 2013.

ATLANTA -- Rob Beanlands, MD, director of the National Cardiac PET Centre and the Molecular Function and Imaging Program at the University of Ottawa Heart Institute, sought to convince physicians that FDG PET is among the best choices in imagining modalities for the assessment of myocardial viability, during an imaging symposium at the 59th annual American College of Cardiology (ACC) conference on March 15.

QATLANTA - Originally piloted two years ago as the Improving Continuous Cardiac Care IC3 registry, the recently rebranded PINNACLE registry is the first and only ambulatory registry for cardiovascular conditions in this country, noted William Oetgen, MD, clinical associate professor of medicine at Georgetown University, at the 59th annual American College of Cardiology (ACC) annual conference on March 16.

ATLANTA While quality improvement measures in the inpatient setting may have been described and collected at healthcare practices for years, performance measures in the outpatient setting have not been systematically collected and the current performance in the outpatient setting is unknown, according to a presentation at the Comparative Effectiveness and Outcomes session at the 59th annual American College of Cardiology (ACC) conference on March 16.

ATLANTA--Currently, cardiovascular imaging accounts for 30 percent of all the medical radiation that people receive in the U.S., noted Andrew Einstein, MD, cardiologist and assistant professor of clinical medicine at Columbia University College of Physicians and Surgeons in New York City, during a symposium at the 59th annual American College of Cardiology (ACC) annual conference on Monday. Einstein also spoke to whether the current levels of radiation are appropriate, as well as strategies for reducing radiation exposure.

ATLANTA--In utilizing the Seattle Heart Failure Model (SHFM), overall survival scores for patients admitted with acutely decompensated heart failure (ADHF) may be improved, according to Samira Bahrainy, MD, department of cardiology at the University of Washington, Harborview Medical Center, and colleagues during the poster presentations held on March 15 at the 59th annual American College of Cardiology (ACC) conference.

Using an advanced massive-training artificial neural network, computer-aided detection (CAD) scheme, radiologists were able to improve their polyp detection rate and reduce the number of false positives in CT colonography, based on a study presented at the 2009 Radiological Society of North America (RSNA) annual conference in Chicago.
