CT Scan / CT ANGIO

64 Slice cardiac dual CT scanner at GHID
A computed Tomography (CT) scan uses x-ray in conjunction with computer algorithms to view the body's organs and tissues.This type ofscan can detect more subtle attenuations of x-rays images with the aid of a computer to generate cross sectional views of the internal organs and structures of the body . Global Hawk Imaging and Diagnostics boasts a 64 slice CT scanner which (as well as 16 Slice CT Sanner) captures up to 64 simultaneous antomical slices of 0.5mm in a single gantry rotation.This scanner has proven revolutionary in helping examine patients who have difficulty holding their breath such as trauma victims,young children or the extremely ill.

The CT Scanning procedure 
 
The CT scanner looks like a giant thick ring. Within the wall of the scanner there is an X-ray source. Opposite the X-ray source, on the other side of the ring are X-ray detectors. The patient lies on a couch which slides into the centre of the ring until the part of the body needing assessment is within the ring. The X-ray machine within the ring rotates around your body. As it rotates, the X-ray machine emits thin beams of X-rays through the body which are detected by the X-ray detectors.

The detectors detect the strength of the X-ray beam that has passed through the body. The denser the tissues the less X-rays can pass through. The X-ray detectors feed this information to a computer and different tissues with different densities show up as an image in many colours or shades of grey. This produces an image of a slice also known as a cross-section of the particular part of the body under assessment.

The couch will move slowly through the ring and the X-ray beam passes through the next section of the body. Several cross-sectional pictures of the part of the body under investigation are made by the computer. At Global Hawk Imaging and Diagnostics our CT scanning systems can produce a 4 dimensional image from the data received.

What is a CT Scan Used for ?
A CT scan can be done on any section of the head or body. It can give clear pictures of bones. It also gives clear pictures of soft tissues which an ordinary X-ray test cannot show, such as muscles, organs, large blood vessels, the brain and nerves. The most commonly performed CT scan is of the brain - to determine the cause of a stroke, or to assess serious head injuries. Other uses of a CT scan include:

• To detect abnormalities in the body, such as tumours, abscesses, abnormal blood vessels, etc, when they are suspected by symptoms or other tests
• To give a surgeon a clear picture of an area of your body before certain types of surgery
• To pinpoint the exact site of tumours prior to radiotherapy
• To help doctors find the right place to take biopsies (tissue samples).

 
What preparation do i need to do before a CT Scan ?
It depends on which part of your body is under examination. You will be given instructions by the CT department. As a general rule you will need to remove any metal objects from your body such as jewelry and hair clips etc. It is best not to wear clothes with metal zips and studs etc. You may be asked not to eat or drink for a few hours prior to your scan - depending on the part of your body to be scanned. If you need an injection of contrast as described below it may be necessary to stop certain medicines before the procedure. This may apply to people taking metformin a medicine used to treat diabetes. If you are taking this medication your doctor should give you instructions.

In some situations depending on what part of the body is being scanned, one of the following may be needed. These aim to block a certain amount of X-ray going through various tissues. This helps to give better contrast between different organs and tissues on the scan pictures.

• For abdominal and pelvic scans you may be asked to have a special drink before the scan. This helps to show up the stomach and bowel more clearly
• For pelvic scans, some fluid may be put into your rectum (back passage)
• For pelvic scans, women may be asked to insert a tampon into the vagina
• Sometimes a dye (contrast medium) is injected into the bloodstream via a vein in your arm. The dye may give you a flushing feeling and an odd taste in your mouth, which soon disappears.

The CT scan itself is painless. You cannot see or feel X-rays. You will be asked to stay as still as possible otherwise the scan images may be blurred. The scan can take between 5 and 30 minutes depending on which part (or parts) of the body is under investigation
