What is CT scanner?
CT scanner uses computer tomography, a technology that increases X -ray images, to create your dimensional visuals of a scanned entity. Sometimes it is also referred to as CAT scanning. The advantage of the CT scanner is that it allows the doctor to create a cross -section of internal organs and structures, allowing them to view from multiple angles at the same time. For many diagnostic purposes, this cross -section provides more accurate representation of what is happening in the body.
CT scanners are often used to diagnose muscle or bone problems, determine the location of tumors or blood clots, determine the point of infection or diagnose internal injuries, including internal bleeding. KT CT scanners are also used to monitor certain health conditions such as cancer and heart disease. The doctor may also use CT scanner as a guide during surgery or radiation therapy.
Some people should not have a CT scan. Women who are pregnant will be the usualpoken to use a different type of diagnostic testto reduce the exposure of the fetus. Some CT scan requires the use of contrasting medium or dyes. Someone undergoing scanning with a contrast medium can experience an allergic reaction to contrast. Preewistic allergies, asthma, diabetes, heart or kidney problems, and some thyroid diseases may increase the likelihood of suffering from an allergic reaction to contrast media.
people who experience reaction to contrast media can develop several symptoms. A slight reaction can result in hives and itching. Some people can develop swelling in the throat, which may be life -threatening. In people with kidney disease, the process of passing through contrast media may be taxed on the kidneys.
The contrast medium is a reflective dye that is injected into a vein. The medium blocks X -rays and shows white in the pictures. This blood vessel, intestinal or other organs are easier to see. IfIt will use contrasting media, it may be necessary several hours before scanning quickly. Depending on what the scan is looking for, it may also be necessary to change someone's diet or take a laxative before the procedure.
Scanning can take place in a hospital or outpatient imaging device. The procedure is relatively fast, with the scanning lasts only a few minutes. You will be asked to lie on a table that slips into the CT scanner display tube. In some cases, the technician may ask you to hold your breath to avoid blurring images. When the scan is complete, your doctor will study the pictures and discuss the results with you.
