CT scans
Computerized tomography, also referred to as a CT or CAT scan, differs from an MRI in that this procedure uses X-rays instead of magnets to create cross-section images of soft tissue, bone, and blood vessels for diagnosing illnesses and injuries or monitoring some treatments. CT scans can be ordered for:
- Cardiac and coronary vessel analysis
- Coronary artery calcification scoring
- Blood clots and enlarged ventricles in the head
- Brain tumors
- Some abnormalities associated with certain mental illnesses
- Enlarged lymph nodes
- Pancreatic disease
- Trauma/emergency situations
- Stroke assessment
- Oncology/cancer care
- Pulmonary emboli
- Inner ear ailments
- Spinal injuries and back problems
- Lung cancer
The scan itself is quick and painless, though it is very important to remain still for the best-possible images.
Some CT scans require fasting, and some require a contrast to be taken for the best-possible images. Your physician will advise you of any special instructions for your scan.
