Adenosine-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 کاملDynamic myocardial perfusion imaging by dual-source computed tomography.
We report a dual-source computed tomography study of dynamic and quantitative myocardial perfusion in a 44-year-old patient with previous documented coronary artery disease. Quantitatively, the tomography showed myocardial perfusion deficit in the territories with significant coronary stenosis, confirmed by computed tomography angiography and conventional angiography. Dual-source computed tomog...
متن کاملIncremental 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 stress high-pitch 128-slice dual-source myocardial computed tomography perfusion for imaging of reversible myocardial ischemia: comparison with magnetic resonance imaging.
BACKGROUND Coronary computed tomography angiography (CTA) enables accurate anatomic evaluation of coronary artery stenosis but lacks information about hemodynamic significance. The aim of this study was to evaluate 128-slice myocardial CT perfusion (CTP) imaging with adenosine stress using a high-pitch mode, in comparison with cardiac MRI (CMR). METHODS AND RESULTS Thirty-nine patients with i...
متن کاملAdenosine triphosphate stress dual-source computed tomography to identify myocardial ischemia: comparison with invasive coronary angiography
PURPOSE The purpose of this study was to investigate the utility incremental diagnostic value of combined assessment with coronary CT angiography (CCTA) and myocardial CT perfusion imaging (CTP) using dual-energy technology with an Adenosine Triphosphate (ATP) load technique. MATERIALS AND METHODS Twenty-one patients underwent ATP-provocation dual-energy CT and CAG. We compared the diagnostic...
