Computed Tomography Scanning

COMPUTED TOMOGRAPHY (CT) SCANNING

ct2141

CT scanning is used in the diagnosis of stroke, blood clots, blockages and disease processes in the body. JRMC CT is accredited by the American College of Radiology.

 

We offer a CT scan of the body and a CT scan of the head.

 

CT SCAN OF THE BODY

CT (computerized tomography) scan of the body is a special x-ray examination that produces a series of cross-sectional pictures or images of the body. During the procedure, the x-ray tube moves in a large circle as it scans or rotates around your body. Receptors relay information to a computer that converts the data into images on a videoscreen. A radiologist will study these images and give a report to your physician. CT scans can distinguish bone, tissue, fat, gas, fluid, etc.

They are used to evaluate organ size and shape, evaluate masses, and diagnose pathology such as tumors cysts, aneurysm, ascites, lymphadenopathy, metastasis, ruptured discs, etc. CT scans can be performed with or without IV contrast.

 

CT SCAN OF THE HEAD

A CT scan (computerized tomography) of the head is a special x-ray examination that produces a series of cross-sectional pictures or images of the brain. It is performed to detect tumors, bleeding or blood clots, enlarged ventricles and otherdisorders that do not show up on conventional x-rays.

During the procedure, the x-ray tube moves in a large circle as it scans or rotates around your head. Receptors relay information to a computer that converts the data into images on a video screen. A radiologist will study these images and give a report to your physician.

 

COMPUTERIZED TOMOGRAPHY ANGIOGRAPHY (CTA)

Computerized Tomography Angiography (CTA) is used to visualize blood vessels within the body including the coronary arteries of the heart.

CT (computerized tomography) angiography (CTA) is an examination that uses x-rays to visualize blood flow in the arteries throughout the body. Beams of x- rays are passed through the area of interest in the body from different angles to create multiple images, which are then processed by a computer to produce a cross-sectional picture. The procedure is used to screen for arterial disease.

 

CTA is commonly used to:

  • Visualize blood flow in the renal (kidney) arteries in patients with high blood pressure and those suspected of having kidney disorders. Narrowing (stenosis) of a renal artery can be a cause of high blood pressure (hypertension) in some patients.
  • Identify an aneurysm in the aorta or other major blood vessels. Aneurysms are diseased areas in a weakened blood vessel wall that bulge out. They can be life-threatening if they rupture.
  • Identify a dissection in the aorta or its branches. Dissection is a condition where the layers of the artery wall separate and peel away from each other.
  • Identify a small aneurysm or arterio-venous malformation inside the brain that can be life-threatening.
  • Detect narrowing or obstruction of arteries in the neck that carry blood from the heart to the brain.
  • Examine arteries in the brain to provide a diagnosis in patients who complain of headaches, dizziness, ringing in the ears, or fainting.
  • In injured patients, examine the arteries for any damage from trauma.
