Myocardial perfusion imaging to assess ischemia using multislice computed tomography.
Multislice computed tomography (MSCT) coronary angiography is an accurate noninvasive anatomic imaging technique; but it cannot determine the functional relevance of the lesions it detects. However, MSCT perfusion imaging can detect the presence of myocardial infarction during rest and assess viability using delayed enhancement. With recent developments in MSCT scanner technology, it has become possible to image myocardial perfusion and the capability of MSCT to determine the presence of ischemia through perfusion imaging during stress is currently being investigated. Although only limited data are available, noninvasive imaging with MSCT has the potential to assess both coronary anatomy and myocardial perfusion in one procedure. This article describes the feasibility of myocardial perfusion imaging using MSCT and its potential use in clinical practice.
