What is angiography CT?
Angiograph with computer tomography (CT) is a imaging device that provides a complex view of blood vessels and arteries in different parts of the body such as heart and brain. This type of scan is used to diagnose a wide range of health conditions. Computer tomography angiograms provide a non -invasive overview of the body only with minimal exposure to radiation.
Just before scanning CT angiography, the nurse connects to the arm of an intravenous line to serve a dye called a contrasting medium. This dye goes through the circulatory system and improves the contrast and details of the images. The patient will then slip into the CT machine for CT angiography procedure, which lasts about 30 minutes. After the scan is completed, the patient may leave freely.
During scanning, X -ray and X -ray detectors revolves around the patient. The detectors notice the amount of X -ray radiation that is prevented by the body and creates an image. A picture of Will represents a slice of the body, similar to a slice of bread. Gradually the patient moves cT by a tube to gather many slices. Slices will then be reconfigured using a computer program to create multidimensional views of the circulatory system.
Angiography CT is used to diagnose many different health conditions. This procedure can be used to inspect aneurism, blocking the arteries or any abnormality in the pattern of blood vessels. Angiographic scanning can also help prepare surgeons for heart surgery or to transplant organs by showing the accurate placement of blood vessels. The ocologist can also use CT angiography to review the vascularization of the malignant tumor.
Angiography associated with CT scan has many advantages. This diagnostic tool can eliminate the need for some types of reconnaissance operations that were once used to look in the health system. The procedure also eliminates the need for angiography dependent on the catheter and almost allH cases, this procedure provides greater details than the catheter angiography.
However, there are several risks of using this display device. During the test, the patient is exposed to low radiation. In addition, some patients have an allergic reaction to the contrast medium used during the test. If this happens, the allergy should be recorded on the patient's medical records to prevent future problems. Finally, some patients are unpleasant in the enclosed scanner space and can become anxious and unpleasant. This can be prevented by giving the patient a sedative before scanning.
In order to prepare for angiography CT, the patient should wear comfortable, free clothes that allow access to injection. If it is given a sedative, the patient should follow all the instructions in preparation for medication, such as fasting or bringing a friend to take him home. Any pain or discomfort at the injection site during the procedure or after the test should be reported to the doctor.
