CT of the Head
CT Brain, a CT scan of the head produces a cross-section of your brain and can provide detailed information on head injuries, stroke, brain tumors and other brain diseases. This imaging technique details bone, soft tissues and blood vessels.
Common Uses of Head CTs
- Detection of bleeding, brain damage and skull fractures in patients with head injuries.
- Detecting a blood clot or bleeding within the brain shortly after a patient exhibits symptoms of a stroke.
- Detection of stroke.
- Evaluation of the extent of bone and soft tissue damage in patients with facial trauma.
- Detection of bleeding in a patient with a sudden severe headache who may have a ruptured or leaking aneurysm.
- Detection of most brain tumors.
- Diagnosing diseases of the temporal bones, which may be causing hearing/balance problems or tinnitis.
- Detection of enlarged brain cavities (ventricles) in patients with hydrocephalus.
- Determining whether infection/inflammation or other changes are present in the paranasal sinuses.
- Planning radiation therapy for cancer.
- Non-invasive assessment of aneurysms or arteriovenous malformations through a technique called CT Angiography.
- Detecting diseases or malformations of the skull.
- CT Angiography depicts blood vessels supplying the brain, revealing aneurysms and vessel narrowing/occlusion.
- Three-dimensional imaging of the skull and brain structures for surgical planning.
CT of the Chest
A CT scan of the chest is often used to further evaluate abnormalities found on routine chest X-rays. Because CT allows much greater clarity of internal organs, bone, soft tissue, and blood vessels than can be seen with routine X-ray, physicians are able to perform a more in-depth study.
Common Uses of Chest CTs
- Further evaluate abnormalities found on routine chest x-rays.
- Help diagnose the cause of symtoms such as cough, shortness of breath, chest pain, or fever.
- Evaluate injury to the chest.
- Detect infections such as pneumonia or tuberculosis.
- Detect lung cancer.
- Demonstrate chronic conditions such as emphysema, bronchiectasis or interstitial lung disease.
- Diagnose vascular abnormalities such as pulmonary emboli (blood clots in the lung vessels) or aortic aneurysm (dilated aorta).
CT of the Body- Abdomen and Pelvis
A CT scan of the body is typically performed on the abdominal and pelvic region. Because CT allows much greater clarity of internal organs, bone, soft tissue, and blood vessels, CT is very well suited for evaluation and diagnosis of numerous disorders that can occur in these regions.
Common Uses of Body CTs
- Diagnose infections such as diverticulitis, appendicitis, or pyelonephritis (kidney infection).
- Detect tumors in the liver, pancreas, or kidney.
- Find stones in the kidney or bladder.
- Evaluate enlarged lymph nodes in lymphoma or leukemia.
- Diagnose and follow aortic aneurysm (enlarged aorta).
- Screen patients with abdominal trauma for organ injury.
- Rapid evaluation of patient with nonspecific abdominal pain.
