A computed tomography scan (CT scan) is a diagnostic imaging test that produces 3-D, layered pictures of a body area using X-rays. CT scans are an accurate and fast way for doctors to visualize your spine, joints, and bones and the organs inside your head, pelvis, abdomen, and chest. Your doctor may also refer to a CT scan as a CAT scan or computed axial tomography scan.
Wait at home, not in the emergency room. Use Dignity Health-St. Rose Dominican Hospitals' online waiting service to select your estimated arrival time for CT scan in Las Vegas and Henderson, NV.
Doctors use CT scans to evaluate a range of conditions and symptoms and provide diagnosis and treatment, including:
A radiologic technician will perform your CT scan in a Dignity Health - St. Rose Dominican radiology clinic or hospital. The scan can last up to 30 minutes.
When you have a CT scan, you lie on a table. It slowly moves through a large, ring-shaped machine. The machine does not completely enclose you, but encircles one part of your body at a time. The technician may ask you to hold still or hold your breath at times while the scanner takes pictures.
Sometimes to give extra clarity for certain body areas, a contrast dye is necessary. Your technician may give you this dye by injection, mouth, or enema. CT contrast dye can cause allergic reactions in rare cases.
Because the scanner exposes you to radiation, CT scans carry a slightly increased risk of cancer. The benefits of CT scans generally outweigh this risk.
CT scans help doctors diagnose:
Your doctor will tell you the results of your CT scan as soon as possible and discuss your options, including treatment recommendations and referrals to specialists.
