CT angiography vs angiogram CT angiography is a less invasive version of the traditional angiogram. The main difference between the two procedures is that while a standard angiogram involves a catheter being inserted into the artery and to the area being studied, a CT angiogram does not require ...

The correlation between extent and severity of coronary artery disease as documented by quantitative coronary angiography and the incidence of cardiac events within 3 years was analyzed from a prospective study. In 73 out of 419 patients, 89 events occurred comprising 10 cardiac deaths, 15 non-...
(Supplementary Table2). For example, a Y-Net model was developed to achieve 3D intracranial artery segmentation from 49 cases of magnetic resonance angiography (MRA) data and has achieved a precision of 0.819 and a DSC of 0.828 for the testing set13. The performance of this model was shown...
A meta-analysis of prospectively randomized controlled trials (PRCTs) was carried out to compare the outcomes of FFR-guided CABG vs coronary angiography (CAG)-guided CABG. Method: The meta-analysis adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two PR...

OBJECTIVES This study sought to evaluate the association between volumetric characterization of target lesions by multidetector computed tomography (MDCT) angiography and the risk of post-procedural myocardial injury after elective stent implantation. BACKGROUND Previous reports have shown that plaque characteri...
Transluminal Attenuation Gradient (TAG) has been proposed as a non-invasive method for evaluating the functional significance of coronary stenoses using CT Angiography (CTA). However TAG has not previously been used to assess CAA. We hypothesized that abnormal flow dynamics in CAA caused by KD ...
CTA = CT angiography, iCA = invasive coronary angiography, CFR-LAD = coronary flow reserve of the left anterior descending coronary artery. Yellow boxes identify minor criteria, Orange are major non-WM criteria, while light red and dark red indicate WM mild and more-than-mild ...
126 Cost Utility of Serial Computed Tomography Angiography vs Magnetic Resonance Angiogram for Small, Unruptured, Internal Carotid Artery Aneurysms: Are Either Worth It?.An increasing number of unruptured aneurysms are being detected as the quality and utilization of imaging modalities expands. Often...
