In modern medicine, radiological examinations play a crucial role in helping doctors make more accurate diagnoses. Two examinations that frequently raise questions among the public are CT scans and MRIs . Many patients are confused about the differences between the two, and when each is needed.
What is a CT Scan?
CT Scan (Computed Tomography Scan) is an examination that uses X-rays with the help of a computer to produce detailed images of body sections.
Advantages of CT Scan:
- The process is relatively fast (usually only a few minutes)
- Suitable for detecting bleeding, fractures, lung disorders, and head injuries
- Very useful in emergency situations, such as accidents or strokes.
What is MRI?
MRI (Magnetic Resonance Imaging) is an examination that uses magnetic fields and radio waves to produce detailed images of organs, soft tissues, and blood vessels without X-ray radiation.
Advantages of MRI:
- Provides better detail on soft tissues (brain, spinal cord, joints, ligaments, internal organs)
- Does not use ionizing radiation, so it is safe for repeated examinations.
- Excellent for detecting tumors, brain disorders, nerve and joint disorders

When Should It Be Done?
The choice of CT Scan or MRI will be determined by the doctor based on the patient's medical needs.
- CT scans are usually chosen in emergency situations or when doctors need fast results, for example in the case of an accident, stroke, or head trauma.
- MRI is more recommended for detailed evaluation of soft tissue, such as brain abnormalities, spinal cord, joints, and tumors.
