The anterior spinal artery was occluded on coronal cone beam CT from spinal angiogram (top right, black arrow), which correlated to the area of signal abnormality (dotted bracket on coronal CISS). Coronal diffusion-weighted images confirm restricted diffusion (short arrows) in the corresponding ...
This paper proposes some methods for the recovery of irregular motion in fluorescein angiograms (FA). The overlying is done by a three step procedure: detection of relevant points, matching points from different images and estimation of the assumed linear geometric transformation. A stochastic model...
Cardiac catheterization.A surgeon inserts a thin tube into a blood vessel and threads it through to your heart, where they inject a special dye. Then they make an image called an angiogram that shows how your blood is moving and where there are blockages. CT scan.Another way to get a lo...
Cardiac catheterization (also called heart catheterization) is a diagnostic and occasionally therapeutic procedure that allows a comprehensive examination of the heart and surrounding blood vessels. It enables the physician to take angiograms, record blood flow, calculate cardiac output and vascular resistan...
Angiogram images of the aorta are taken to decide where the covered stent should be placed. The stent graft is then advanced into position. Confirming X-rays are taken. If needed, the covered stent is adjusted to form a seal. Additional angiogram images are taken to confirm whether the posit...
(B) Representative angiogram from each study group. (C) Greater collateral artery diameters were observed in rats receiving BH4 + L-arginine; addition of vitamin C further increased collateral diameter. Data are means ± sd; n = 6. *p < 0.05 for BH4 + L-arginine or BH4 + L-arginine +...
procedure if there are complications with the surgery. Moreover, the kind of impact the entire episode has on a person’s self esteem is considerable. When deciding to go under the knife for cosmetic treatment such as a cheek implant surgery, research should be thorough and informed. Make ...
Rarely, angiography may be used to diagnose subdural hematoma. During angiography (angiogram), a catheter is inserted through an artery in the groin and threaded into thearteriesof the neck and brain. A special dye is then injected, and an X-ray screen shows blood flow through the arteries ...

Regional left ventricular function was analyzed quantitatively from serial contrast angiograms serving as the reference standard of myocardial viability. Furthermore, the influence of vessel patency or recurrent stenosis after revascularization on functional outcome was assessed. 1. Methods Patient selection....
