What is CT scanning with contrast?

Scanning of computer tomography (CT) with contrast allows doctors to better see specific areas inside the body. CT scan, sometimes called calculated axial tomographic (CAT) scanning, uses X -rays to ensure a cumulative view of body structures from multiple angles. The contrast material is a dye that emphasizes specific organs or tissues during the CT process and facilitates these structures for the physicians to see in the pictures that result in. Using CT scanning with contrast, the doctor can explore all parts inside the patient's body for signs of the disease. Cross -sectional images that are the result of scanning facilitate early detection of tumors, abscesses, abnormal blood flow and symptoms of many other serious conditions, so these diseases can be treated in time. Other contrasting materials include gastrofraphine, barium and barium sulphate, each of which can be administered as oral, rectal or intravenous (IV) contrast. Patients who have to undergo CT scan with contrast canTheir doctors require not to eat solid food four to six hours before scanning. If a person is allergic to contrasting material, a person may need special medicines before the scan to safely undergo the procedure.

Injection dye, served by vein in the hand or forearm of the patient, is used to highlight blood vessels or main organs and structures such as the brain, spine or liver. The dye is sometimes injected directly to a place that the doctor wants to study, such as a knee or elbow joint. In oral contrast administration, often used for abdominal scanning, the patient is obliged to drink contrasting material before his CT scanning. The time interval between the drinking of contrasting material and the subject of CT scan varies and the interval depends on which part of the body the doctor wants to explore. Rectal administration, performed through enema, is used when doctors need to study the large intestine.

next toThe more effects of CT scanning with contrast may include blood clots, dizziness, nausea and hives. Patients who have multiple scanning could develop an allergy to contrasting material over time. Anyone who has experienced adverse effects as a result of the previous CT scan should communicate to his doctor before the procedure. Before CT scan with contrast, patients should inform their doctors about all the medicines they use and all the health conditions they are treated.
