A CT scanner, also known as Computerized Axial Tomography or CAT scan, is a method of using x-rays that combines a computer with x-ray images to create 3D or cross-sectional views of both internal structures and organs in the body. It may also help identify normal or abnormal sections in the body and assist with treatments or placing instruments when necessary. It provides now necessary guidance in the diagnostic process and as well as in many accompanying treatments.
The CT scanner operates by taking x-ray images in a large machine that is shaped similar to a donut. It captures the images all around the body. Each image shows a small sliver or slices of the body and gets recorded on a film known as a tomogram so doctors or technicians can look at it. The body can be recreated on film or in pictures by stacking them on top of each other so it’s like you’re viewing the actual body in x-ray form.
It’s essential to remain still during a CT scan because moving can severely impact the quality of the images that are produced. It’s possible for the CT scanner to get an entire image of the body from your head down to your feet in less than one minute. This unprecedented speed and accuracy allows for a faster rate of on-point assessment of a patient’s need. It also enables an increased number of diagnoses to be rendered.
A doctor may also require contrast dye in order to capture accurate images so they are clearer. It can be consumed orally or injected in a vein in the hand or forearm. This contrast may cause an odd burning sensation, warm flushing in the body or give you a metallic taste in your mouth which will pass within a few seconds. At that point, a great deal of information can be recorded.
CT scans are done for a number of reasons and to help diagnose many specific conditions. They can help to diagnose infections, guide surgeons to access the exact area when performing a biopsy, find tumors and masses that are both cancerous and benign and examine blood vessels.
The risks of CT scanners are minimal and typically involve being exposed to higher levels of radiation or having a bad reaction to the contrast dye but they are minimal and your doctor should address them with you at the time you receive the scan.
