Dipyridamole Stress and Rest Myocardial Perfusion by 64-Detector Row Computed Tomography in Patients With Suspected Coronary Artery Disease

OBJECTIVES: Recently, stress myocardial computed tomographic perfusion (CTP) was shown to detect myocardial ischemia. Our main objective was to evaluate the feasibility of dipyridamole stress CTP and compare it to single-photon emission computed tomography (SPECT) to detect significant coronary stenosis using invasive conventional coronary angiography (CCA; stenosis >70%) as the reference method.

  1. Interesting study and shows promising results in the context of stress CT. Initially, stress CT research showed great promise with few proof of concept studies, but overall have not gained acceptance yet in clinical practice. Identification of perfusion defect by CTA is sometimes challenging.
