CT Scan in Israel

What is CT scan used for?
A CT scan can be used during biopsies to direct a surgeon to the correct area that is being examined.
It is also used to diagnose diseases and identify tumors and cancers.
Furthermore, a CT scan may also be used to aid the study of blood vessels.

How is a CT scan performed?
A CT scan is performed by a radiology technologist. The patient needs to lie down on a narrow table that goes into the middle of the CT scan machine. Depending on the part of the body that is being scanned, the patient is required to lie on the back, side or stomach. When the patient is inside the CT scan machine, x-ray beams circle the patient. The quantity of x-rays that are required to scan the body part is measured by small detectors within the scanner. Information from the scanner is taken by a computer that produces individual images called slices. These images are viewed on a monitor and they can be saved and printed. By placing the slices together, three-dimensional images of the organs are produced.

During a CT scan, the patient is required to remain still to generate clear images. If the patient moves during the procedure, it may result in the images being blurred. Additionally, the patient may be required to hold breath for short times.

How to prepare for a CT scan?

• For some CT scans, a special dye known as contrast is inserted into the body before the procedure. This is done to highlight the particular areas in the body, which results in clear images. The contrasts are inserted into the body in various ways depending on the type of CT scan. It can be done through an IV inserted in the arm or with an enema through the rectum. Alternatively, the patient may be required to drink the contrast.
• Some patients who are allergic to these intravenous dyes may be required to take medication.
• The patient may be required to stop eating or drinking 4 to 6 hours before the CT scan if a contrast is being used.
• If the patient weighs above 300 pounds, the patient should inform the doctor. CT scan machines usually have a weight limit, and the scanner operator may need to be contacted to make adjustments.
• Patients need to remove metal jewelry before a CT scan.
• The doctor should be informed about any medication that the patient may be taking.
• The patient should also inform the doctor about certain medical conditions of the patient such as:
  • Pregnancy
  • Allergy to any medication
  • Heart problem
  • Diabetes
  • Kidney problem
  • Asthma
  • Multiple myeloma
