Myocardial Perfusion Analysis from Adenosine-Induced Stress MDCT

Abstract

Abstract. Myocardial perfusion assessment is of paramount importance for the diagnosis of coronary artery disease. This can be performed using different image modalities such as single-photon emission computed tomography (SPECT) or magnetic resonance imaging (MRI). Recently, cardiac multiple-detector computed tomography (MDCT) has shown promising results with the benefit of gathering data regarding coronary anatomy, ventricular function and myocardial perfusion in a single study. Preliminary results for three different methods for automatic assessment of myocardial perfusion from adenosine-induced stress MDCT are presented.

Exploring Different Parameters to Assess Left Ventricle Global and Regional Functional Analysis from Coronary CT Angiography

“…In that sense, the myocardium attenuation analysis and new parameters that can help gather insight over myocardial perfusion, and support the visual assessment method (prone to variability), are most welcome. Some preliminary work has already been presented by the authors concerning myocardial perfusion assessment from adesonise‐induced stress MDCT [SBL*11] and it is, at the moment, our main focus.…”

“…This could also be extended to show local data although care should be taken as, to reduce computational cost, local data is not computed for all slices. The option of superimposing data over the myocardium itself can also be interesting in some scenarios (refer to Silva et al [SBL*11] for an example concerning myocardial perfusion assessment).…”
