A CT (computed tomography) scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to create detailed images of the inside of the body, including bones, muscles, organs, and blood vessels
. CT scans are more detailed than standard X-rays and can be used to detect various conditions, such as cancer, heart disease, muscle and bone disorders, and internal injuries
. Some key aspects of CT scans include:
- Purpose : CT scans are used to diagnose diseases or injuries, guide treatment plans, and help with procedures like surgeries, biopsies, and radiation therapy
- Procedure : During a CT scan, the patient lies on a narrow, motorized table that slides through the opening of a doughnut-shaped scanner. The X-ray beam moves in a circle around the body, allowing for multiple views of the same organ or structure and providing greater detail
- Contrast Agent : CT scans are often performed with and without a contrast agent to improve the radiologist's ability to see certain structures and abnormalities
- Duration : The entire procedure typically takes about 24 to 48 hours, although in an emergency setting, results may be available within an hour
CT scans are painless and noninvasive, and they can be performed on any part of the body
. They are frequently used in conjunction with other diagnostic tests, such as MRI scans and X-rays, to provide a more comprehensive understanding of a patient's condition
