What is a CT Scan?

Computerized Tomography takes images in slices and is often described by many as a sliced loaf of bread.  The scanner rotates around the body to take images from multiple planes. The computer then generates image in many different planes to assist our highly trained Radiologists in diagnosing abnormal pathologies.

CT may be recommended by your physician if organs such as heart, liver, lungs, kidneys, bladder, pancreas, spleen, gallbladder, reproductive organs, stomach, small and large intestine need to be evaluated more or when conventional X-ray (single plane images) are unable to diagnose the area of interest.

Sometimes Contrast is needed to assist in diagnosing certain pathologies. The contrast can be injected (Intravenously), given orally (by mouth) or both depending on the exam ordered.

CTA means Cat Scan Angiography.  Angiography is a CAT scan with contrast.  This is a study specifically to look at blood flow to determine if there are any blood clots, aneurysms, and stenosis and also to determine if surgical intervention is required. CTA’s provided by DSP Health System are for PE (Pulmonary Embolism), AA (Aortic Aneurism), AAA (Abdominal aortic aneurysm). CTA Neck(Carotid Stenosis). CTA Runoff (Peripheral Vascular disease),  and CTA Brain.

How should you prepare for your CT study?

You should wear loose comfortable clothes with no zippers or metal.  If this is not possible the technologist may ask you to change into a gown depending on the exam ordered. You will also be asked to remove any jewelry in the area to be scanned.

The technologist will contact you If your exam is a contrast study.  This is to prescreen you for the test and give instruction for your CT Scan. The contrast consists of iodine base so it is important to notify the technologist if you have any allergies. Please also inform the technologist if you are pregnant or may suspect you are pregnant.  You will need to fast for 4 hours prior to any contrast study so if possible schedule your exam on a day that is convenient for you to do so.
