Incremental value of adenosine-induced stress myocardial perfusion imaging with dual-source CT at cardiac CT angiography.
PURPOSE First, to assess the feasibility of a protocol involving stress-induced perfusion evaluated at computed tomography (CT) combined with cardiac CT angiography in a single examination and second, to assess the incremental value of perfusion imaging over cardiac CT angiography in a dual-source technique for the detection of obstructive coronary artery disease (CAD) in a high-risk population...
متن کاملAdenosine-induced stress myocardial perfusion imaging using dual-source cardiac computed tomography.
OBJECTIVES This study sought to determine the feasibility of performing a comprehensive cardiac computed tomographic (CT) examination incorporating stress and rest myocardial perfusion imaging together with coronary computed tomography angiography (CTA). BACKGROUND Although cardiac CT can identify coronary stenosis, very little data exist on the ability to detect stress-induced myocardial per...
متن کاملCT myocardial perfusion imaging
Computed tomography (CT) is capable of comprehensively assessing the heart in order to provide information on anatomy, function, perfusion and viability. CT coronary angiography can assess both the coronary artery lumen and the characteristics of atherosclerotic plaques. CT myocardial perfusion imaging can provide additional information compared to CT coronary angiography by highlighting areas ...
متن کاملClinical Utility of Coronary CT Angiography with Stress Perfusion CT in Preoperative Cardiac Risk Evaluation
BACKGROUND AND OBJECTIVES Vascular surgery carries high operative risk. Recently developed cardiac computed tomography (CT) provides excellent imaging of coronary artery disease (CAD), as well as myocardial perfusions. We investigated the role of stress perfusion CT with coronary computed tomography angiography (CCTA) using 128-slice dual source CT (DSCT) in preoperative cardiac risk evaluation...
متن کاملCertainty of stroke diagnosis: incremental benefit with CT perfusion over noncontrast CT and CT angiography.
PURPOSE To systematically evaluate the diagnostic benefits and inter- and intraobserver reliability of an incremental computed tomographic (CT) protocol in the confirmation of clinically suspected stroke, with combined imaging and clinical data as the reference standard. MATERIALS AND METHODS Institutional review board approval was obtained, and participants gave informed consent. A total of ...
