结论基于冠状动脉CTA影像计算的AccuFFR ®ct系统可以作为评估冠状动脉狭窄引起功能性缺血的一种快速、准确的计算工具。 关键词: FFR;FFR-CT;计算流体力学;冠状动脉CTA;狭窄。 ABSTRACT ObjectiveTo compare non-invasive coronary blood fractional flow reserve based on coronary CTA (FFR-CT) imaging with invasive...
Diagnosis of ischemia-causing coronary stenoses by noninvasive fractional flow reserve computed from coronary computed tomographic angiograms. Results from the prospective multicenter DISCOVER-FLOW (Diagnosis of Ischemia-Causing Stenoses Obtained Via Noninvasive Fractional Flow Reserve) study[J]. J Am ...
In patients with non–ST-segment elevation acute coronary syndrome (NSTEACS), coronary pathology may range from structurally normal vessels to severe coronary artery disease. Objectives The purpose of this study was to test if coronary computed tomography angiography (CTA) may be used to exclude cor...
Computational simulations of coronary artery blood flow, using anatomical models based on clinical imaging, are an emerging non-invasive tool for personalized treatment planning. However, current simulations contend with two related challenges – incompl
CT-ECV回顾 首先先带着各位朋友复习一下上节课的内容，还记得的朋友请自动跳到第二节。虽然传统上使用心脏 MRI 进行无创采集，但心脏 CT-ECV是一种新兴的应用。碘化造影剂是一种细胞外造影剂，弥漫性心肌纤维化和淀粉样沉积都会增加细胞外心肌空间，导致异常心肌中碘化造影剂的浓度升高。在ECV的计算上，对于单...
Both found CTA can help determine if if a patient should be sent for a diagnostic angiogram, or if a non-invasive exam is good enough to determine if revascularization is needed.[13,14] "This is very relevant as we try to reduce the number of invasive coronary angiograms in a COVID-...

We conducted a prospective single-center study involving patients with known or suspected stable ischemic heart disease who underwent SPECT-MPI using CZT-SPECT and SPECT/CT scanners, and the latter was equipped with cardiofocal collimation. Experienced physicians performed analysis and reporting based on...
