What is a CT scan
A Computed tomography (CT) Scan can provide complete information about the body, including the chest (lungs and heart), head (inner ear, eyes, brain and its vessels), skeletal system (spine, shoulders and neck), bladder, pelvis and hips, gastrointestinal tract, reproductive system. This scan is commonly used in emergencies as this scan does not take much time and the whole procedure generally takes fewer than 5 minutes.
Purpose CT scan
A CT scan is typically used to detect one of the following:
- Blood clot within the brain
- Brain tumors
- Skull fractures
- Degree of soft tissue damage
- Diagnose bone and muscle disorder
- Internal injuries
Preparation for CT scan
You need to fast for nearly two to four hours prior this scan. Your doctor could ask you to stop certain medication before the scan. You cannot wear your jewellery during this scan as metals hinder with the MRI machine’s ability to produce images. Therefore you need to remove all your jewelry prior undergoing this scan.
Procedure of CT scan
A CT scan is performed in a hospital’s radiology department. Once you met all the criteria needed to carry out this scan, you will be asked to lie down on the procedure table and after that the whole process starts. The X-ray tubes and detectors rotate around you and produce various detailed images of your body.
