OBJECTIVES: A prespecified secondary objective was to determine if stress perfusion cardiovascular magnetic resonance (CMR) was noninferior to single-photon emission computed tomography (SPECT) for detecting significant CAD and for excluding significant CAD. (bvsalud.org)
METHODS: Participants with known or suspected CAD underwent a research rest and stress perfusion CMR that was compared with a gated SPECT performed using standard clinical protocols. (bvsalud.org)

Radiation1
The American Heart Association recommends that in nonemergency settings, patients should be informed of the risks (including those associated with radiation) and benefits involved in the use of cardiac CT scanning, radiopharmaceuticals, and fluoroscopy. (medscape.com)
Evaluation1
Careful evaluation of the patient's history and physical examination (including signs of congestion, such as jugular venous distention [JVD]) can provide important information about the underlying cardiac abnormality in heart failure. (medscape.com)
