The image is taken in with the x-ray tube in left anterior oblique position. [8] To image the vessels of the neck such as common carotid, internal and external carotid arteries, AP, lateral, and 45 degrees bilateral oblique positions are taken. Contrast injection rate is 3 to 4 ml/sec with total volume of 7 to 9 ml.
The X-ray images taken may either be still, displayed on an image intensifier or film, or motion images. For all structures except the heart, the images are usually taken using a technique called digital subtraction angiography or DSA. Images in this case are usually taken at 2–3 frames per second, which allows the interventional radiologist ...
This occurs when plaques (made up of deposits of cholesterol and other substances) build up over time in the walls of the arteries. Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries. [8] As the disease progresses, plaque buildup can partially block blood flow to the heart ...

Image of contrast enhanced dual-source coronary CT-angiograph. Computed tomography angiography (CTA), an imaging methodology using a ring-shaped machine with an X-ray source spinning around the circular path so as to bathe the inner circle with a uniform and known X-ray density. Cardiology uses are growing with the incredible developments in CT ...
The mask image is simply an image of the same area before the contrast is administered. The radiological equipment used to capture this is usually an X-ray image intensifier, which then keeps producing images of the same area at a set rate (1 to 7.5 frames per second). Each subsequent image gets the original "mask" image subtracted out.
Coronary artery bypass grafting (CABG): A bypass surgery improves blood flow to your heart by taking another blood vessel from somewhere else in your body and using it to create a new passage for ...
The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the: Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal lobes [1]
