CT-Scans
At Western Radiology we perform a variety of CT scans, dependent on your medical needs.

Computed Tomography (CT) is a diagnostic procedure that uses special X-ray equipment to obtain cross-sectional pictures of the body. The CT computer displays these pictures as detailed images of organs, bones, and other tissues. A CT scan allows us to look at your body in cross-section (like looking at the slices of a loaf of bread in turn). Using the CT scanner and a powerful computer, we can build up a picture of the whole area showing both soft tissue and bone, and see parts of the body which are difficult to see by any other method.This procedure can also be called CT scanning, computerised tomography, or computerised axial tomography (CAT).

During a CT Scan, the patient lies very still on a table. The table slowly passes through the center of a large X-ray machine. The patient may hear whirring sounds during the procedure. Patients also may be asked to hold their breath at times, to prevent blurring of the pictures. Often, a contrast agent, or “dye,” may be given orally, injected into a vein, or given both ways before/after the CT scan is done. The contrast dye can highlight specific areas inside the body, resulting in a clearer picture. CT Scans do not cause any pain. However, some patients may find lying in one position during the procedure to be slightly uncomfortable. The length of the procedure depends on the size of the area being scanned.

Some patients may be concerned about the amount of radiation they receive during a CT Scan. We use digital radiography that contains a very minimal dose.

In very rare cases, contrast agents can cause allergic reactions. Some people experience mild itching or hives (small bumps on the skin). Symptoms of a more serious allergic reaction include shortness of breath and swelling of the throat or other parts of the body. Patients must inform the technician immediately if they experience any of these symptoms, so they can be treated promptly.
