Computed tomography angiography (CT-angiography, CTA) allows noninvasive visualization of coronary arteries (CA). This method is highly sensitive in detecting coronary atherosclerosis. However, standard CTA does not allow evaluation of the hemodynamic significance of found CA stenoses, which requires additional functional tests for detection of myocardial ischemia. This review focuses on possibilities of clinical use, limitations, technical aspects, and prospects of a combination of CT-angiography and CT myocardial perfusion imaging in diagnostics of ischemic heart disease.

Omarov et al. (2020) conducted a review in Ischemic heart disease. CT-angiography combined with stress CT myocardial perfusion imaging vs. Standard CT-angiography was evaluated on Diagnosis of ischemic heart disease and hemodynamic significance of coronary artery stenoses. Combining CT-angiography and stress CT myocardial perfusion imaging evaluates both coronary anatomy and the hemodynamic significance of stenoses in diagnosing ischemic heart disease.
