Abstract
Cardiac single photon emission computed tomography (SPECT)/ computed tomography (CT) has been introduced to provide anatomical information on such as coronary calcification combined with functional information of myocardial perfusion imaging. Fusion imaging provides accurate coregistration of coronary stenosis and perfusion abnormalities, and allows identification of reduced coronary flow reserve. This article shows an overview of relevant literature including clinical value in SPECT/CT.
Highlights
Ischemic heart disease is a multifactorial entity that can be diagnosed through non-invasive tests such as nuclear cardiology examination and computed tomography (CT) [1]
The stress myocardial perfusion imaging plays an important role in the risk-stratification of the patients with suspected coronary artery disease, diagnosing the extent and severity of infarction and ischemia induced by both epicardial coronary arteries and resistance vessels [2]
If the ischemia-causing coronary stenosis is identified by non-invasive imaging,the culprit lesion can be determined as a therapeutic target of coronary intervention [5]
Summary
Ischemic heart disease is a multifactorial entity that can be diagnosed through non-invasive tests such as nuclear cardiology examination and computed tomography (CT) [1]. The stress myocardial perfusion imaging plays an important role in the risk-stratification of the patients with suspected coronary artery disease, diagnosing the extent and severity of infarction and ischemia induced by both epicardial coronary arteries and resistance vessels [2]. The relationship between ischemia and coronary artery narrowing can be accurately diagnosed by fusion imaging between single photon emission computed tomography (SPECT)and CT coronary angiography [5].
