CT Scan
A Computerized Tomography (CT) scan uses x-rays and computer systems to create three-dimensional images of different areas of the body. During a CT scan, the patient lies on the CT table which moves in and out of a large, donut shaped scanner, taking multiple images of the area being scanned
and digitally assembled to form an extremely detailed view of the bones and soft tissues. The scan is painless procedure and patient experience no claustrophobia due to wide open bore of scanners.
When CT scans are used

- Brain diseases like tumors, atrophy, hydrocephalous etc
- Bone conditions, and injuries
- Abdominal & pelvic diseases
- Kidney stones
- Head injury and ischemia

- Respiratory diseases
Safety
CT scans are generally safe; they do expose you to slightly more radiation than normal x-ray. The amount of radiation you’re exposed to can vary depending on the type of scan you have. In most cases, the benefits outweigh any potential hazards.
Contrast medium
For some CT scans, such as those investigating the brain or abdomen, you may be given contrast medium beforehand. This is a liquid that contains a dye that shows up clearly on the images of certain tissues or blood vessels. It helps distinguish blood vessels from other structures in your body. Contrast medium can be given in different ways, depending on the part of your body being scanned. It can be swallowed in the form of a drink, given as an enema in your back passage, or can be injected into your bloodstream (intravenously).
If your kidney function is poor, contrast medium isn’t usually given intravenously as it can depress kidney function further.
Saral Health Care relies on non-ionic contrast which is considered world’s safest contrast media. Contrast medium is harmless and will pass out of your body in your urine.
