What is an MRI Scan? Understanding the Process
When a doctor suggests an MRI scan, it can feel confusing or even worrying. Many patients wonder what an MRI scan is, why it is needed, and whether it will be uncomfortable. The good news is that an MRI scan is a safe, painless, and non-invasive test used to look inside the body in great detail.
Doctors commonly recommend MRI scans to clearly view organs, tissues, joints, and the nervous system. It helps them diagnose problems early and plan the right treatment.
This simple guide explains what an MRI scan is, why it is done, what happens during the MRI scan procedure, and how to prepare for it. Advanced diagnostic centres like Indian Scans in Tambaram use modern MRI technology to deliver accurate results while keeping patient comfort a top priority.
What is an MRI Scan?
An MRI scan stands for Magnetic Resonance Imaging. It is a medical test that creates clear and detailed images of the inside of your body. Doctors use these images to understand what is happening in organs, tissues, bones, and joints.
An MRI scan works using strong magnets and radio waves. These signals are processed by a computer to produce detailed pictures. Unlike X-rays or CT scans, MRI scans do not use radiation.
Because of this, MRI scan safety is high, making it suitable when detailed imaging is needed without radiation exposure. MRI scans are commonly used for the brain, spine, joints, and internal organs.
Why is an MRI Scan Done?
An MRI scan is done to help doctors diagnose health conditions accurately and at an early stage. Doctors may recommend an MRI scan for:
- Brain and spinal cord conditions such as headaches, nerve problems, stroke, or spine disorders
- Joint, muscle, and ligament injuries in the knee, shoulder, or back
- Heart and blood vessel issues
- Abdominal and pelvic organ evaluation
- Tumour detection and disease monitoring
Types of MRI Scans
- Brain MRI: For headaches, dizziness, strokes, tumours, and nerve conditions
- Spine MRI: Identifies disc problems, nerve compression, and back pain
- Joint MRI: Detects ligament tears and joint damage
- Abdomen & Pelvis MRI: Examines liver, kidneys, uterus, and prostate
- Contrast MRI: Uses dye for clearer visibility when required
