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 insertion of a catheter...
Complications. Most people who haveangiography do not have complications, but there's a small chance of minor or more serious complications. Possible minor complications include: an infection where the cut was made, causing the area to become red, hot, swollen and painful – this may need to ...
CONSTITUTION:Artifact of a static part is corrected utilizing a difference of amplitude to generate an angiogram of high quality. A rephase image R and a dephase image D are inputted. Phases of the phase images R and D inputted are matched. The image with a phase distortion matched is ...
