The “tomography” word comes from a Greek word “tomos”, which means slice. Computed tomography or CT scan provides a detailed view of the body. A CT scan use ionizing radiation just like x-rays and it makes to be able to create a set of images (like slices) which can be composed as a single one.

The CT scans help to find the location of a tumor to checking for internal bleeding after the trauma. As obviously, doctors use this tool in surgeries and other medical procedures as well as for monitoring the treatment.

Computed Tomography

The CT scanner is a health care, hi-tech equipment, medical technology, and diagnosis. The scans are used by a radiologic technologist, who will guide all the procedure. The equipment is looking like a huge ring or donut, its big enough for you can fit into. During the exam, the table will slide into the hole, of the machine. The internal parts of the CT machine will start to spin around the body, but you won’t be able to see what is happening, because of the machine's casing. Even so, you will be able to hear loud whirring noises as the internal parts start to rotate around you. And depending on what body part is being scanned the CT machine may also move over you.

During the exam you must stay still because the CT could cause a blurry image. Interestingly, even something as minor as breathing can affect to the image. Depend on where the scan is focusing on, at this time the technologist can ask you to hold your breath briefly. The scan could take anywhere between a few minutes to an hour. You will also be able to talk to the radiologist at any time of the procedure if you have been experienced any discomfort or anxiety because of the intercom system.

Computed Tomography

In some cases, the CT scan may need to be discharged after you have taken medical contrast dye, if its needed, you will be asked for take in orally or intravenously, depending on the procedure of course. It's true, that this will increase how long the procedure will take because the contrast need time to make its way through your body. Obviously, the CT scans use radiation, which in large doses, can raises a patient’s risk of cancer. But the risk is exceptionally low of the developing cancer from a CT.
