What is a CT Scan?
A commonly used diagnostic imaging technique, CT (Computerized Tomography) scan combines a sequence of X-ray images captured from varying angles and utilises computer processing to generate cross-sectional images of the bones, blood vessels & soft tissues.
Ideal for quickly examining people who have suffered internal injuries or some kind of trauma, a CT Scan offers a much more comprehensive overview than a regular X-ray.
It can be utilised to visualise almost all body parts and is generally used to diagnose disease/injury in addition to helping plan medical, surgical or radiation treatment.
What are the types of CT Scan?
There are many different types of CT Scans, which are used depending on the area of the body to be evaluated. The most common types of CT Scans include:
- CT Angiography – CT Brain / Abdomen & Pelvis
- Cardiac CT – HRCT Chest
- CT Neck / PNS
- CT Angiography
- Cardiac CT
How does a CT Scan work?
The CT Scan is based on the x-ray principle. It involves combining a series of x-ray images taken from various angles and then utilising a blend of complex hardware & software technologies to generate 3D images of the internal organs and body structures.
The 3D images have a high contrast ratio between bone, tissue, blood vessels & other body parts. These images are stored as electronic data files and generally examined on a computer. A radiologist evaluates these images before sending a report to the doctor.
When should we do a CT Scan?
A doctor or health practitioner usually recommends a CT Scan to help:
- Cases of bowel perforation, head / body trauma
- Identify the location of a tumour, infection or blood clot
- Guide procedures like surgery, biopsy & radiation therapy
- Detect & monitor diseases and conditions like cancer, heart disease, lung nodules & liver masses
- Monitor the effectiveness of specific treatments, like cancer treatment
- Identify internal injuries & fractures.
Conclusion
CT Scan is basically an upgrade on regular X-rays. It provides a significantly better overview of the problem an individual may be suffering from, helping doctors assess the issue and chalk out an effective treatment plan.

FAQ’s
Generally speaking, the entire CT scan procedure, including preparation, takes around an hour to complete. However, the actual scanning lasts for only around 10-30 minutes. This can vary if apatient needs to undergo scan with contrast.
A CT scan involves combining a series of x-ray pictures captured from varied angles around the human body and then utilising computer processing to generate cross-sectional images (slices) of the blood vessels, soft tissues & bones.
