CT Scan Overview
 Our CT Scanners are equipped with state-of-the-art technology called “multi-slice” imaging, which provides more mini “slice” pictures of the body’s interior than traditional CTs. This allows us to capture clearer, sharper views of anatomical structures. When physicians can see what’s inside more clearly, they can make better diagnoses.
This technology allows faster examination times than in the past, which reduces the amount of time our patients spend at their appointment.
IMPORTANT NOTE:
Any woman who is pregnant, or thinks she might be, should let her doctor know before proceeding with a CT scan

What is a CT Scan (Computer Tomography)?
A CT scan is the process of creating cross-sectional images of any part of the body. During the exam, a thin x-ray beam scans multiple points about the periphery of the body part. A computer then reconstructs the data creating two-dimensional x-ray images or "slices." CT examinations compliment other imaging exams such as x-ray films by offering physicians an additional tool in which to view anatomy. In some cases, CT provides diagnostic information that cannot be achieved with any other method.

Procedure: What can I expect?
The technologist will bring you into the CT scan room where the procedure will be explained to you. The technologist will help you onto the cushioned table.
As the procedure begins, you will hear a whirring sound as the x-ray tube moves in the machine. The table will move slightly as each picture is taken. To obtain the best possible images, it is important that you lie very still during the exam.
Depending on the type of examination you are having, you may receive an intravenous (IV) injection of contrast material (x-ray dye). Sometimes scans are performed prior to receiving x-ray dye and then repeated after the dye is a given. In either case, the technologist will explain each step of the examination.
The technologist will communicate with you during your exam through a microphone. You may be given "breathing" instructions during your exam. Scan times depend on the type of exam and number of body parts imaged, but typically are less than 30 minutes. If you are having a biopsy during your CT scan, you will be asked to sign a permission (consent) form. The exam is more involved and therefore may last more than 30 minutes.

Preparation
Do not eat or drink anything for 2 hours before your exam. If you take medications, ask your doctor if you should take them before your CT scan. Any medication should be taken with a small sip of water. If you are having an examination of your abdomen or pelvis, you will be given a flavored drink to outline your intestines and stomach.

Afterwards
Occasionally, additional imaging is needed; you may be asked to lie on the table again for more scans. The radiologist will review the images from your CT Scan and provide a detailed report to your physician. Your physician will discuss these results to you and explain what they mean relative to your health.
