the basal and mid septal segments, corresponding to significant stenoses in the LAD and RCA. (B) Coronary angiography reveals significant stenoses in the LAD and RCA. Figure 2: (A) Myocardial perfusion MRI with SW-CG-HYPR detects perfusion defects in the mid anterior, septal, and inferior segments, corresponding to significant stenoses in the LAD and RCA. (B) DE shows subendocardial hyperenhancements in the mid inferoseptal and inferior segments. (C) CA reveals significant stenoses in the LAD and RCA.

Adenosine-induced stress myocardial perfusion MRI using SW-CG-HYPR with whole left ventricular coverage: comparison of results with X-ray angiography in patients with suspected CAD

Results The prevalence of CAD was 55%. In the per-patient analysis, the sensitivity, specificity and accuracy of SW-CG-HYPR myocardial perfusion imaging were 95%, 83% and 90%, respectively. In the per-vessel analysis, these values were 98%, 89% and 93%, respectively. Figure 1 illustrates the detection of significant CAD by SW-CG-HYPR myocardial perfusion imaging with correlation to X-ray corona...

Myocardial perfusion MRI using SW-CG-HYPR for the detection of coronary artery disease

In this work, we have prospectively examined the diagnostic value of adenosine-induced stress myocardial perfusion MRI using SW-CG-HYPR in 50 patients with suspected CAD. Using the high-resolution, whole left ventricle SW-CG-HYPR method, perfusion MRI was able to depict hemodynamically relevant coronary artery stenosis with an accuracy of 90% and 93% based on perpatient and per-vessel analyses,...

Myocardial perfusion MRI with SW-CG-HYPR: a comparison to conventional SR-Turbo-FLASH and x-ray angiography in patients with suspected coronary artery disease

In the current study, we prospectively compared the diagnostic value of SW-CG-HYPR and conventional SRTurbo-FLASH for myocardial perfusion MRI in patients with suspected CAD. Compared with conventional SRTurbo-FLASH, SW-CG-HYPR allows increased spatial coverage (whole left ventricular coverage), improved temporal and spatial resolution and SNR, reduced motion artifacts and has higher diagnostic...

The prognostic value of stress/rest gated myocardial perfusion SPECT in patients with known or suspected coronary artery disease

Introduction:Gated myocardial perfusion SPECT has diagnostic and prognostic values in coronary artery disease (CAD). We tried to determine prognostic values of the left ventricular perfusion & functional indices as well as transient left ventricular dilation (TID) derived from gated myocardial perfusion SPECT. Methods: 1820patients who underwent gated myo...

Myocardial perfusion scan accuracy in detection of coronary artery disease - Comparison with exercise stress test [Persian]

Introduction: In patients with coronary artery disease (CAD) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. Exercise stress test is conventionally the first study used in evaluation of CAD. Considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. Methods: Patie...
