A magnetization-prepared sequence, T-2-Prep-IR, exploits T-1, T-2, and chemical shift differences to suppress background tissues relative to arterial blood, The resulting flow-independent angiograms depict vessels with any ...

To reduce the scan time of time of flight or phase contrast angiography sequences, fast three-dimensional k-space trajectories can be employed. The best 3D trajectory depends on tolerable scan time, readout time, geometric ...

Cardiovascular disease is the leading cause of mortality worldwide, with atherosclerotic coronary artery disease (CAD) accounting for the majority of cases. X-ray coronary angiography and computed tomography coronary ...

In this work, three-dimensional (3D) spiral imaging has been utilized for magnetic resonance coronary angiography, Spiral-based 3D techniques can dramatically reduce imaging time requirements compared with 3D Fourier ...

Arterial spin labeling is a well-known noninvasive angiography technique, which does not necessitate the use of a contrast agent. arterial spin labeling is still clinically underused because of several challenges: (1) long ...

The aim of this study is to perform imaging of irises of different colors using spectral domain anterior segment optical coherence tomography angiography (AS-OCTA) and iris fluorescein angiography (IFA) and compare their ...

PURPOSE: To compare the time-of-flight and contrast-enhanced- magnetic resonance angiography techniques in a 3 Tesla magnetic resonance unit with digital subtraction angiography with the latest flat-panel technology and ...

© 2020 American College of Cardiology FoundationCoronary artery disease remains the leading cause of cardiovascular morbidity and mortality. Invasive X-ray angiography and coronary computed tomography angiography are ...

The X–ray angiography images are routinely used to assess the blood vessels. The acquisition procedure considers a medical imaging system which allows obtaining views of the vessel while the blood flows thought them. The ...

Background: There are guidelines about equipment, premises, personnel, indications and complication rates for coronary angiograph\y, that every center personnel, indications and complications rates for coronary performing ...
