Medical professionals use computed tomography, also known as CT scan, to examine structures inside your body. A CT scan uses X-rays and computers to produce images of a cross-section of your body. It takes pictures that show very thin “slices” of your bones, muscles, organs and blood vessels so that healthcare providers can see your body in great detail.
Traditional X-ray machines use a fixed tube to point X-rays at a single spot. As X-rays travel through the body, they are absorbed in different amounts by different tissues. Higher density tissue creat a whiter image than other tissues against the black background of the film. X-rays produce 2D images. CT scans have a doughnut-shaped tube that rotates the X-ray 360 degrees around you. The data captured provides a detailed 3D view of the inside of your body.
During the test, you will lie on your back on a table (like a bed). If your test requires it, a healthcare provider may inject the contrast dye intravenously (into your vein). This dye can make you feel flushed or have a metallic taste in your mouth.
When the scan begins:
The bed slowly moves into the doughnut-shaped scanner. At this point, you will need to stay as still as possible because movement can create blurry images.
The scanner takes pictures of the area the healthcare provider needs to see. Unlike an MRI scan, a CT scan is silent.
When the exam is over, the table moves back out of the scanner.
