Importance of CT- Angiography
Doctors use angiography to detect and treat problems with the cardiovascular system's blood 
vessels. Angiography procedures capture images of the body's major arteries. Contrast 
material is used in some diagnostic procedures.
To do angiograms, doctors use:- 
• Catheterized x-rays
• CT scans, or computed tomography
• Imaging with a magnet and radio waves
To create high-resolution images of blood arteries and surrounding tissues, CT angiography 
uses computed tomography (CT). Contrast material is administered through a catheter into 
an arm vein during the exam. While the contrast material is pumped through the patient's 
veins and arteries, a CT scan will be performed to obtain high-resolution images.
What is the process like?
Traditional X-ray imaging and CT scanning share many commonalities. In standard X-ray 
imaging, a single X-ray source fires a beam of rays across the patient's body. A detection plate 
captures the X-rays emitted from the body. The image will appear in varying colors of grey 
depending on how much X-ray light is blocked by various human organs. On an X-ray, bones 
appear white, while air looks dark.
In CT scans, several X-ray beam sources and arrays of X-ray detectors spin rapidly around the 
patient's body. The X-ray beam sources send multiple narrow beams with high energies 
through the body. The detectors detect the X-rays released from the body and will be rolled 
through the CT scanner to expose various body parts to the scanner's X-ray beams. After 
collecting data from the scanner, a powerful computer will use it to create images of the 
human body. 
The computer generates two- and three-dimensional images of the body from a vast amount 
of CT scan data.
Radiologists will use high-tech computer software and display to examine these images for 
signs of disease.
To see the blood arteries clearly, contrast material is used during procedures to make them 
seem stark white.
How should one be prepared for CT- Angiography
• Dress loosely and comfortably for the exam.
• The CT pictures may be distorted if the patient wears metal objects such as jewelry, 
eyeglasses, dentures, or hairpins. 
• Underwired bras made of metal must be removed. You should stop getting pierced.
• Your doctor will suggest you fast for a certain amount of time before your exam if 
contrast material is used. 
• Inform your doctor about undergoing medications or any allergies. Your doctor may give 
drugs (often steroids) to lessen the likelihood of an adverse reaction if you have a history 
of sensitivity to contrast material. 
• If a woman has any reason to suspect she is pregnant, she should tell both her doctor and 
the CT tech.
 
 
The Importance of CT Angiography
Detailed images of the 
inside of your head, neck, 
body, legs, and arms help 
doctors diagnose. It is non-
invasive, precise, and rapid, 
and it may be used in real-
time to monitor the 
condition of blood arteries 
during surgical procedures. 
While CT scans expose 
patients to radiation, the 
amount absorbed by the 
body is negligible.
• Avoid surgery using 
angiograms. Accuracy in 
surgery is improved if it is 
still required.
• When compared to traditional angiography, CT angiography has the advantages of being 
quick, painless, and less prone to problems.
• Compared to more traditional forms of angiography, such as catheter angiography or 
magnetic resonance imaging (MRI), CT angiography can offer more accurate anatomical 
data.
• Sedation or general anaesthesia is unnecessary for CT angiography.
• Coronary artery blockages can be detected via CT angiography of the heart.
• CT angiography may be less expensive than catheter angiography.
• After a CT exam, the patient is exposed to no residual radiation.
Protecting Yourself from Radiation: A Word
During X-ray examinations, doctors take extra precautions to limit radiation exposure while 
capturing clear images for diagnosis. The procedures followed by radiologists are subject to 
constant scrutiny and revision by national and international radiological protection 
organizations.
Controlled X-ray beams and 
dose control procedures 
are used in modern X-ray 
systems to reduce the 
amount of unwanted stray 
(scatter) radiation. This 
reduces radiation exposure 
to parts of your body that 
aren't being scanned.
CT angiography will be 
performed with as little 
radiation as possible using 
scan parameters 
customized to your body. 
Scan areas will be 
restricted to the target 
organ to reduce exposure 
to unneeded radiation.
