A CT scan (computerized tomography) is a diagnostic imaging procedure that uses a combination of X-rays and computer software to produce detailed images of the body.
Indications
CT scans provide more detail than plain x-rays and have largely replaced them for the imaging of certain structures. Indications may include the following:
- Kidney stones
- Hematuria
- Renal cyst or mass
- Recurrent infection (urinary)
- Operative planning
- Staging of cancer
Procedure
The patient lies still on a special table, which is part of the CT scanner, and while the table moves, numerous x-rays are taken in rapid sequence. Depending on the indications for the study, IV and /or oral contrast may be given. During the scan the patient may be given instructions to hold their breath for a few seconds if possible. The entire process takes only a few minutes.
Patients should follow the appropriate instructions prior to this procedure.
Side Effects
Please let us know if you have any allergy to contrast agents or iodine, have renal insufficiency or if you are taking any medications for the management of diabetes. Some patients experiencing a reaction will have hot flashes, nausea or vomiting. These reactions are usually treated successfully with antihistamines.
