2023, Progress in Cardiovascular DiseasesSpecificity of Myocardial Perfusion Imaging: Issues With Proposed MBS Item Review
2019, Heart Lung and CirculationCitation Excerpt :Third, we focussed on specificity and therefore are unable to comment on sensitivity of MPS. The sensitivity of MPS has been reported in the literature as around 84% [15,16]. The majority of studies use ≥50% stenosis as the mark of significant coronary artery disease.
Comparison of treadmill exercise versus dipyridamole stress with myocardial perfusion imaging using rubidium-82 positron emission tomography
2005, Journal of the American College of CardiologyCitation Excerpt :In this study, patients preferred treadmill exercise to dipyridamole stress. Previous studies have found similar sensitivity (60% to 94% vs. 48% to 100%) and specificity (68% to 100% vs. 64% to 100%) of exercise and dipyridamole thallium-201 and technetium-99m single photon emission computed tomography in detecting significant coronary stenoses (20,21). However, one study found that dipyridamole thallium-201 may be more sensitive than exercise thallium-201 (70% vs. 52%) in detecting coronary stenoses between 40% and 60% (21).
Combined dipyridamole-exercise stress echocardiography for detection of myocardial ischemia in hemodialysis patients: An alternative to stress nuclear imaging
2002, American Journal of Kidney DiseasesCitation Excerpt :In dialysis patients, stress nuclear imaging has been shown to both detect CAD and predict future coronary events.5,21 Nevertheless, isotopic cardiac imaging is limited by a lack of specificity22 resulting from the classic isotopic attenuation phenomenon in the posterior wall19 and the frequent presence of left ventricular hypertrophy in dialysis patients.23 In this study, we used Myoview, an exclusive marker of myocardial perfusion with high energy, good myocardial uptake, and slow myocardial clearance.14,15
