how to prepare for your scan


X-ray


•     The faculty may want you to wear loose, comfortable clothing that you can easily move around.
•     The faculty may also ask you to remove any jewellery or other metallic items from your body before             your X-ray is taken.
•     If your gastrointestinal tract is to be examined, the patient must fast for some time before the                       examination.
•     Radiologists must be informed about any previous implants.
•     If you are pregnant or suspect you may be pregnant, tell your doctor and our staff including our                   technologist. X-rays on pregnant women are avoided near the womb, though on occasion the health           benefits of diagnosing and treating your condition may outweigh the risk. Your doctor and out                     technologist will discuss all your options with you.
•    Children are also at greater risk from radiation, so there should be a clear medical reason for any                  child to receive an X-ray.
•    We want your exam to be as comfortable and hassle-free as possible, so we provide all                                     the information you’ll need to prepare before you arrive.

Preparing for your x-ray exam
Your physician or our staff will provide specific instructions to make you, as certain exams require different preparation. A typical x-ray exam requires no special preparation. Eating: If you are scheduled for a diagnostic X-ray using a contrast agent, you may be asked to refrain from eating before the exam. Check with your physician or call our office for instructions.

Ultrasound

•     A trained technician presses a small, hand-held device, about the size of a bar of soap, against your            skin over the area being examined, moving it as necessary to capture the image. The transducer sends     sound waves into your body, collectssound waves that bounce back and sends them to a computer,        which creates the images.

•    What to wear: You should wear loose, comfortable clothing, avoiding garments that have zippers,                belts or buttons made of metal. Objects such as keys or wallets that would be in the area being                      scanned   should be removed.

•    Prior exams: Inform your physician if you recently had a barium examination or have been injected            with a contract material for a computed tomography (CT) scan or radioisotope scan.
You may have to wait 10 to 14 days before undergoing a DXA test.
•   Pregnancy: You should inform your physician and x-ray technologist if there is any possibility that             you are pregnant. Many imaging tests are not performed during pregnancy so as not to expose the               foetus to any radiation. If an x-ray is necessary, precautions will be taken to minimise radiation                   exposure to the foetus.
