CT (Computed Tomography)
CT of the Head
An CT of the head is generally used when an MRI is not a viable option. This may be due to the presence of a pacemaker or non-compatible aneurysm clips. A CT of the head is used to assess the pathology of the head and the cranial structures.
CT Coronary Artery Screening
Coronary Artery Screening (Calcium Scoring) is a low dose CT scan used to detect calcium deposits or plaque buildup in the coronary arteries of the heart. Calcium or plaque deposits restrict flow in the blood vessels, suggesting a likelihood of future cardiovascular events. An increase in calcium deposits can be symptom free, but may put a person at greater risk for heart attack.
CT Lung Screening
CT Lung Screening is a low dose CT scan designed to visualize pathology of the chest and aid in early detection of lung cancer. This screening technology is more sensitive than x-rays at detecting small lung nodules that would not be visualized on a routine chest x-ray. The majority of lung cancers can have no symptoms and experts hope that earlier detection will translate into earlier treatment with improved treatment outcomes.
CT of the Chest, Abdomen, and/or Pelvis
This particular group of low dose CT scans screens the chest, abdomen and pelvic areas for pathology. This is done by producing cross sectional images that enable detailed evaluation of anatomy and pathology. Oral and intravenous contrast materials are often used to differentiate internal structures. If a patient has known pathology, monitoring changes is recommended.
CT Bone Densitometry
CT Bone Densitometry is most often used to diagnose Osteoporosis, a condition that often affects women after menopause but may also be found in men and rarely in children. Osteoporosis involves a gradual loss of calcium, as well as structural changes, causing the bones to become thinner, more fragile and more likely to break.
