Computerized Angio-Tomography Test
The method which involves a dose of contrast material enriched with iodine and computed tomography to help diagnose and evaluate blood vessel diseases or related conditions, such as aneurysms or blockages is known as Computed tomography angiography (CTA).
Talk to your doctor if there is a possibility that you are pregnant and tell about any recent illness, medical condition, medications you are taking, and allergies. Your healthcare provider will ask you not to eat or drink anything for several hours before the procedure. If you have a known sensitivity to contrast materials, your doctor may prescribe medications to reduce the risk of an allergic reaction. These medications must be taken 12 hours before the test. Leave the jewels at home and wear loose and comfortable clothes. You could be asked to put on a robe. If you are breastfeeding, talk with your doctor about how to proceed.
What is computed tomography angiography ?
Angiography is a minimally invasive medical examination that helps best CT scan Centre in Delhi diagnose and treat diseases. Angiography uses one of three diagnostic imaging technologies and, in most cases, an injection of contrast material is needed to produce images of the major blood vessels throughout the body.
Angiography is done by:
X-rays with catheters
Computed tomography (CT or CT scan)
Nuclear magnetic resonance (NMR)
Computed tomography angiography uses a CT scanner to produce detailed images of the blood vessels and tissues of various parts of the body. In general, iodine-rich contrast material (ink) is injected through a small catheter placed in a vein in the arm. Then, while the contrast flows through the blood vessels to various organs of the body, a CT scan is performed. After the exploration, the images are processed using a special computer and a program and are reviewed from different planes and projections.
What are the benefits and risks?
Benefits
Angiography may eliminate the need for surgery. If surgery continues to be necessary, it can be carried out more precisely.
Computed tomography can detect the narrowing or blockage of blood vessels allowing to carry out a therapy that could correct the problem.
Computed tomography can provide more precise anatomical details than Nuclear Magnetic Resonance (NMR), unusually small blood vessels.
Many patients may undergo computed tomography angiography, instead of conventional catheter angiography (catheterization), to diagnose blood vessel problems.
Compared to catheter angiography, which requires the placement of a catheter (plastic tube) in the groin within one of the larger blood vessels, injection of contrast material, and possibly sedation or general anesthesia, angiotomography Computerized is faster, is not invasive, and presents fewer complications.
Computed tomography is a useful way to detect arterial diseases (such as narrowing of blood vessels in the heart) and venous, as well as structural abnormalities of the heart before symptoms appear, or when symptoms are not related with a disease of the blood vessels, such as a heart attack.
Angiotomography is a test with a lower cost than that of catheter angiography. It also has the potential to cause less discomfort, because the contrast material is injected into a vein in the arm, rather than injected into a catheter inserted into a major artery or vein.
