CT 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 کاملPerfusion CT in Colorectal Cancer: Comparison of Perfusion Parameters with Tumor Grade and Microvessel Density
OBJECTIVE The purpose of this study was to prospectively compare pre-operative computed tomography (CT) perfusion parameters with tumor grade from colorectal adenocarcinoma (CRC) and to correlate pre-operative CT perfusion parameters with microvessel density (MVD) to evaluate angiogenesis in CRC. MATERIALS AND METHODS Pre-operative perfusion CTs were performed with a 64-channel multidetector ...
متن کاملDynamic CT perfusion imaging of acute stroke.
BACKGROUND AND PURPOSE Because cerebral perfusion imaging for acute stroke is unavailable in most hospitals, we investigated the feasibility of a method of perfusion scanning that can be performed rapidly during standard cranial CT. Our aim was to identify the scanning parameters best suited to indicate tissue at risk and to measure a perfusion limit to predict infarction. METHODS Seventy pat...
متن کاملC-Arm Conebeam CT Perfusion Imaging in the Angiographic Suite: A Comparison with Multidetector CT Perfusion Imaging.
BACKGROUND AND PURPOSE Perfusion imaging in the angiography suite may provide a way to reduce time from stroke onset to endovascular revascularization of patients with large-vessel occlusion. Our purpose was to compare conebeam CT perfusion with multidetector CT perfusion. MATERIALS AND METHODS Data from 7 subjects with both multidetector CT perfusion and conebeam CT perfusion were retrospect...
متن کاملAdaptive statistical iterative reconstruction improves image quality without affecting perfusion CT quantitation in primary colorectal cancer
OBJECTIVES To determine the effect of Adaptive Statistical Iterative Reconstruction (ASIR) on perfusion CT (pCT) parameter quantitation and image quality in primary colorectal cancer. METHODS Prospective observational study. Following institutional review board approval and informed consent, 32 patients with colorectal adenocarcinoma underwent pCT (100 kV, 150 mA, 120 s acquisition, axial mod...
