Go Through Coronary Computed Tomography Angiography to Diagnose Heart Problem Easily
The coronary computed tomography angiography (CTA) is a computed tomography technique used to visualize arteries and vessels of the heart. This technique helps to determine fatty or calcium deposits that have narrowed to the coronary arteries. It needs a special type of X-ray examination, and for the best possible image; patients have to take an iodine-containing contrast material as an intravenous (IV) injection.
Computed tomography angiography (CTA) is a computed tomography technique by which arteries and venous vessels of the body can be visualized. This is a noninvasive medical test that combines special X-ray equipment along with sophisticated computers to produce multiple images of the inside of the body. In this way the cross-sectional images of the coronary are examined on a computer monitor or printer.
The coronary CTA is referred to the patients who have suspected abnormal coronary arteries, symptoms like chest pain, unclear or inconclusive stress test, high-risk for coronary disease, fatigue during heavy physical activity etc. During the coronary CTA examination, x-ray pass through the body and images are taken by the scanner. It is also called “multi-detector” or “multi-slice” CT scanning. The three-dimensional images taken by the detector are used to identify the coronary arteries and plaques in the walls, if any. During the treatment procedure, any contrast material introduced to the bloodstream can be viewed very clearly. During coronary computed tomography angiography test, physician will clean three small areas of the chest to place small, sticky electrode patches there. These electrodes are attached to an electrograph monitor to chart heart’s electrical activity. Now the images taken by CT scan largely support to detect coronary problem.
