"What special preparations and instructions should I know?"

Patients having CT scans schedule without contrast medium require no special preparation.

In preparation for a CT scan with the use of intravenous or oral contrast medium, patients are often asked to be NPO (nothing by mouth) four hours prior to having the exam. The only exception is for patients that are on prescribed medications. Prescribed medications may be swallowed with a small amount of water.

Patients who require oral contrast need to arrive one hour prior to their appointment to drink the contrast and allow it to advance to the intestines. If desired, patients may come to our center prior to their appointment date to obtain oral contrast and start the drinking at home.

"What is a contrast agent and why do I need it?"

A contrast agent is a safe liquid substance that makes certain tissues stand out more clearly against their surroundings. Contrast improves diagnostic accuracy. You may be given a contrast agent orally or intravenously. In all cases the contrast will leave the body naturally within a few hours. It is extremely important to drinking plenty of fluids after having a CT study performed. Drinking fluids helps the body expel the contrast medium through normal body functions.

"How long will the procedure take?"

The length of your CT exam depends upon which particular study or studies your doctor has ordered. Most exams are quick, lasting just a few minutes.

"What if I am claustrophobic?"

Only a small portion of the body is inside the machine at any time. Most patients do not find it uncomfortable. However, if you have had difficulty with a CT, pleasure make your doctor aware. We are able to give a mild sedative to assist in easing your anxiety.

"What risks are associated with PET/CT?"

A PET/CT study is similar to other diagnostic procedures, such as CT and Nuclear Medicine. The radiopharmaceuticals in PET/CT imaging rarely cause any side effects.

"What happens after the exam?"

You may leave as soon as the scan is complete. If you normally drive, you should have no trouble driving yourself home. You may need a driver if you have had medication to relieve anxiety. You may resume eating and drinking, unless otherwise instructed. Drinking plenty of fluids will help you excrete the radiopharmaceutical from your system.

"When will I get my results?"

Your scan will be read by a board certified radiologist with specialized training in the interpretation of PET/CT imaging. Normally, results will be forwarded to your own physician within 24 hours of interpretation.
