CT Scan or Computed Tomography scan procedure is an important diagnostic tool that can show your doctor what is going inside your body. CT scan provides images of human bones, internal organs, blood vessels, and soft tissues. A doctor may also suggest the CT scan of the head, chest, and abdomen if it seems necessary. A CT Scanning system provides a more detailed image than the regular X-Ray.

One can get a scan at the hospital or your trusted diagnostic center. It is normally advisable not to eat or drink before a few hours of the procedure. The duration of the scan can depend on what parts of the body are being scanned. Well, it can take anywhere from a few minutes to half -an -hour. CT scan procedure systems produce ionizing radiation.

5 things to know before having a CT Scan (الاشعة المقطعية)

  1. CT scan is extremely a better choice for examining the bones- A broken leg or a bone disease can be easily located in the CT Scan. It is a faster method of imaging, so usually, it is used in the case of accidents or sudden pain or discomfort. If you are wondering why your doctor has ordered a CT, he/she wants to get a detailed report on what is wrong.
  2. Works by reconstructing images- Basically, CT Scan uses X-ray to take pictures from varied angles and feeds them into the computer. The computer assembles the different pictures or views of the body and forms a diagnostic scan. The doctor can see the images of CT Scan on the screen, X-ray, etc
  3. Pregnant women are not recommended for a CT Scan- It is very important to tell the doctor if you are pregnant or would be pregnant, as the ionizing radiation may have adverse effects on the baby. One cannot have a CT Scan if pregnant and will be advised for another type of Scan like MRI.
  4. CT Scans do not hurt- The machine may rotate around the patient’s body, but does not touch his/her body. The patient is supposed to lie down on the table gently. There may be times when the radiologist asks the patient to hold the breath and not move, as this helps to create better pictures. Usually, the entire process does not take more than 30 minutes.
  5. A shot of contrast is needed with CT Scan- To make the images of the CT Scan clear, a specific type of dye is used called contrast. The doctor usually recommends a contrast if the scan includes the abdomen or the blood vessels. The dye is given as an injection or asked to swallow it. Very few people are allergic to the contrast, and the doctor may prescribe a medication to block the reaction.

A severe reaction to a CT Scan (الاشعة المقطعية ) is rare, as it carries small risks. CT and MRI are better to evaluate soft tissues. A spine CT test is most commonly used to detect a herniated disk or narrowing of the spinal cord. Sinus disease can be easily detected by narrowing the sinus pathway. Most CT Scans are conducted as an out-patient scan and do not require hospitalization
