Evaluating Myocardial Perfusion SPECT: The Normal Study
Key points • The first fundamental assumption of myocardial perfusion SPECT imaging is that the radiotracer is distributed in the myocardium directly proportional to the blood flow at the time…
Choice of Stress Test
Key points • Exercise (treadmill or bicycle) is the preferred stress modality in patients who can exercise and achieve adequate exercise endpoints. • Vasodilator stress is reserved for patients who…
Serial Testing
Key points • MPI has been extensively studied to examine the effects of interventions or changes using well-validated techniques. • Variations in imaging protocol, tracer dose, processing, and quality could…
Patients With PCI and CABG
Key points • PCI and CABG are commonly used modalities for revascularization in patients with stable and unstable CAD. • Ideally, stress testing (in conjunction with imaging) should be used…
Use in Stable Patients With Known or Suspected Coronary Artery Disease
Key points • Stress MPI remains the most common imaging modality used in patients with known or suspected CAD. • The improvement in hardware and software and the availability of…
Other Forms of Heart Disease
Key points • Myocardial ischemia can be due to diseases other than coronary atherosclerosis. Examples include endothelial dysfunction, bridging of coronary arteries, coronary artery spasm, LV hypertrophy, and certain types…
Patients with Acute Coronary Syndrome
Key points • Acute coronary syndrome encompasses a wide spectrum of clinical presentations, including UA, non–ST elevation MI, and ST elevation MI. • Patients with ST elevation MI are preferably…
Radionuclide Angiography
Key points • RNA is a time-honored method for assessment of LVEF and RVEF. • RNA-derived EF is based on count changes and not on geometric assumptions. • RNA can…
Interpretation, Reporting, and Guidelines
Key points • Image interpretation is not the same as “pattern recognition” as it requires knowledge of tracer kinetics, instrumentation, protocols, cardiac physiology, etc., skills that are acquired from years…
