Image Quality and Radiation Dose for Prospectively Triggered Coronary CT Angiography: 128-Slice Single-Source CT versus First-Generation 64-Slice Dual-Source CT
This study sought to compare the image quality and radiation dose of coronary computed tomography angiography (CCTA) from prospectively triggered 128-slice CT (128-MSCT) versus dual-source 64-slice CT (DSCT). The study was approved by the Medical Ethics Committee at Tongji Medical College of Huazhong University of Science and Technology. Eighty consecutive patients with stable heart rates lower...
متن کاملComparison of blood flow models and acquisitions for quantitative myocardial perfusion estimation from dynamic CT.
Myocardial blood flow (MBF) can be estimated from dynamic contrast enhanced (DCE) cardiac CT acquisitions, leading to quantitative assessment of regional perfusion. The need for low radiation dose and the lack of consensus on MBF estimation methods motivates this study to refine the selection of acquisition protocols and models for CT-derived MBF. DCE cardiac CT acquisitions were simulated for ...
متن کاملAdenosine Stress High-pitch 128-slice Dual Source Myocardial Computed Tomography Perfusion For Imaging Of Reversible Myocardial Ischemia: Comparison with Magnetic Resonance Imaging Feuchtner et al: Myocardial Perfusion Imaging with CT
Background Coronary computed tomography angiography (CTA) enables accurate anatomic evaluation of coronary artery stenosis, however lacking information about hemodynamical 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 magnetic resonance imaging (CMR). Methods and Resul...
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 کاملStress and rest dynamic myocardial perfusion imaging by evaluation of complete time-attenuation curves with dual-source CT.
OBJECTIVES This study sought to describe a protocol for myocardial perfusion imaging using dipyridamole stress, with 128-slice dual-source computed tomography (CT), and to assess the ability of CT myocardial perfusion imaging (MPI) to detect abnormal flow reserve and infarction in comparison with nuclear MPI (NMPI). BACKGROUND CT MPI has not been previously described with the 128-slice dual-s...
