Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

AHA: Cardiac imaging management cuts unnecessary follow-up tests

A cardiac imaging management program prevented unnecessary imaging exams and resulted in a 12 percent reduction in the likelihood of follow-up tests, including myocardial perfusion imaging and cardiac CT scans, according to a poster presentation Nov. 4 at the American Heart Association annual scientific meeting.

Are chest pain imaging guidelines triggering overdiagnosis?

Current guidelines that call for routine noninvasive testing of low-risk chest pain patients may be based on outdated evidence and should be scrutinized via randomized trial, according to an article in the Oct. 22 issue of Archives of Internal Medicine.
