The Computerized Tomography (CT) Department at Olathe Medical Center
Computerized tomography — also called CT, CT scan and CAT scan — is an X-ray technique that produces more detailed images of your internal organs than do conventional X-ray exams. X-rays are a form of energy — radiation. Conventional X-ray exams produce two-dimensional images. But CT uses an X-ray-sensing unit, which rotates around your body, and a large computer to create cross-sectional images (like slices) of the inside of your body.

A conventional X-ray of your abdomen, for example, shows your bones, as well as subtle outlines of your liver, stomach, intestines, kidney and spleen. A CT scan, however, reveals these bones and organs as well as your pancreas, adrenal glands, ureters and blood vessels — all with a higher degree of precision.

Who is it for?
CT is a noninvasive way to view your internal organs and tissues.

CT is used to help:

• Diagnose muscle and bone disorders, such as osteoporosis
• Pinpoint the location of a tumor, infection or blood clot
• Guide procedures such as surgery, biopsy and radiation therapy
• Detect and monitor diseases such as cancer or heart disease, and monitor the progression of a disease
• Detect internal injuries and internal bleeding

Unlike MRI, CT exams can be done even if you have a pacemaker or cardioverter defibrillator — devices implanted in your chest to help regulate your heartbeat. However, if you're pregnant or suspect you might be, tell your doctor. Your doctor may suggest postponing the procedure or choose an alternative exam that doesn't involve radiation, such as ultrasound or MRI.

Diagnostic Radiology
Diagnostic Radiology produces images of the body using small amounts of ionized radiation. Olathe Medical Center's Radiology Department provides numerous diagnostic x-rays including chest x-rays, orthopedic x-rays as well as specialized exams of the GI tract and urinary system. Board-certified technologists perform the x-rays. The technologists have training in positioning patients, radiation protection, and physics.

What is interventional radiology?
Interventional radiologists (IRs) use their expertise in reading X-rays, ultrasound and other medical images to guide small instruments such as catheters (tubes that measure just a few millimeters in diameter) through the blood vessels or other pathways to treat disease percutaneously (through the skin). These procedures are typically much less invasive than traditional surgery.

Who are interventional radiologists?
Interventional radiologists are medical doctors who have specialized in doing medical procedures that involve radiology. Radiologists use imaging equipment such as X-rays, magnetic resonance (MR) imaging, ultrasound and computed tomography (CT) to diagnose disease. IRs are board-certified radiologists that are fellowship-trained in percutaneous interventions using guided imaging. The American Board of Radiology certifies their specialized training.
