CT (Computed Tomography)

What is a CT Scan?

A CT scan, also called X-ray computed tomography (X-ray CT) uses X-ray images taken from different angles to produce cross-sectional,tomographic images, virtual 'slices', of specific areas of a scanned object, allow the radiologist to see inside the object without cutting.

CT-Scan

Digital geometry processing

Digital geometry processing is used to generate a 3D (3 dimensional) image of the inside of the object from a large series of 2D (two-dimensional) X-ray images. These 3D images are put together to generate the image of a particular organ.

FAQ

The CT study should only take from 3-5 minutes depending on the study.

Depending on the type of imaging exam you will have, your preparation prior to the imaging exam will be different. For instance, you may need to prepare for the examination up to 24 hours in advance by fasting or observing a special diet, or you may be instructed to simply eat and behave normally.
Some questions you may be asked before having certain diagnostic imaging tests might include:
  • Are you pregnant?
  • Are you allergic to iodine or any medication?
  • Have you had any head surgery?
  • Have you ever had a heart surgery?
  • You ever had joint surgery or replacement?
  • Do you wear permanent eyeliner?
  • Have you ever worked with metal?
  • Do you have any metal objects implanted in your body (such as an artificial hip replacement or pacemaker)?
Your doctor may order your exam with or without contrast. If he/she has ordered contrast, a liquid iodine dye is injected into your vein. It will enhance lesions present in many organs.

Patients should lay still and relax during a CT study. Patients may hear the CT scanner rotating during the study. Depending upon the type of study being performed the whirring noise may be very quiet or more noticeable. The table will move very slowly during the CT data acquisition. Depending upon the type of study being performed, the table will either move in several small increment of a few millimeters (for example for a CT of the brain), or the table will move in one large continuous step, for example 20 or 30 cm for a CT of the lungs.

The CT study should only take from 3-5 minutes depending on the study.
