Radiology: CTA can be more appropriately targeted for PE diagnosis

Web Exclusives | Monday, June 14 2010
Written by Lisa Fratt

A new study suggests that CT angiography (CTA) can be better targeted to patients with risk factors for pulmonary embolism (PE).  The study also indicates CTA may be overused in many patients with suspected PE. Thromboembolic risk factor assessment could suffice for many patients, eliminating CTA and helping reduce radiation exposure and CTA costs. Results of the study appear in the online edition and August print issue of the journal Radiology.

Features | Tuesday, February 02 2010
Written by Michael Bassett
While the technology behind cardiac advanced visualization (AV) can create some amazing images, it provides much more than just a “wow” factor. Radiologists and cardiologists rely on it to help them increase productivity and workflow and reduce costs, diagnose more quickly and accurately, and better communicate results with referring physicians and their patients.

Study: Abnormalities revealed by CT may not exclude kidney donors

Clinical Studies | Monday, January 18 2010
Routine CT scanning of the renal arteries and kidneys of middle-aged individuals can commonly present radiographic abnormalities, but the majority of the imaging findings are not perceived to be harmful enough to prevent kidney donation, according to a January study published online in Clinical Journal of the American Society of Nephrology.

CMS Webinar: Incentive payments to offset EHR adoption, not reimburse
