In addition to diagnostic CT scanning (CT abdomen, chest, head), the radiologists at Radiology Physicians utilize CT for the following procedures.


CT Guided Percutaneous Biopsies

CT scans guide the radiologist in needle placement to extract tissue samples. These procedures remove cells to allow accurate diagnosis of abnormalities seen on the scans. This is done instead of invasive surgical procedures.


CT Guided Drainages

CT percutaneous drainages are performed to remove fluid from the site of disease or injury. CT images identify a path for placement of a needle which is inserted to aspirate or drain the specific body part. A tube (catheter) is often left in the fluid, to allow continued drainage.


CT Angiography

CTA is a method of evaluating the vascular system using reconstructions of CT-acquired data. Angiography is an examination of vessels of the abdomen, brain and extremities and has typically been done through a catheter with x-ray contrast or dye injected into the artery, and then a scan is produced. With CT angiography the procedure is non-invasive, as the injection is made in a peripheral vein. This procedure is completed in a less invasive manner than traditional angiography which results in less discomfort and risk at a lower cost.


Cardiac Calcium Scoring

This test detects the amount of calcification present in the coronary arteries which allows an accurate prediction of the likelihood of narrowing of coronary arteries. Calcium is easily detected by CT scanning. The test provides a Coronary Artery Calcification Score based on the amount of calcification present. The scan is recommended for middle aged adults 35-70, with one or more risk factor including high cholesterol, high blood pressure, family history of heart disease, obesity, smoking and sedentary lifestyle.
