What is an MRI Scan? Everything You Need to Know

 

In today’s healthcare world, early and accurate diagnosis is the key to better treatment and recovery. One of the most powerful tools used by doctors for diagnosis is the MRI scan. If you or someone you know has been recommended an MRI, it’s natural to have questions.

This blog will help you understand what an MRI scan is, why it's done, how it works, and how platforms like CareBox can help you book it easily and affordably.

What is an MRI Scan?

MRI stands for Magnetic Resonance Imaging. It is a medical imaging technique that uses strong magnetic fields and radio waves to create detailed images of the internal parts of your body, including the brain, spine, joints, heart, and organs.

Unlike X-rays or CT scans, MRI scans do not use any radiation, making them a safer option—especially for repeated imaging or for children and pregnant women (with doctor’s approval).

Why Do You Need an MRI?

Doctors usually recommend an MRI when they need more information than what an X-ray, ultrasound, or CT scan can provide. MRI scans help detect a wide range of medical conditions, such as:

• Brain tumors, stroke, and memory issues

• Spine and disc problems like herniation or injury

• Joint and ligament damage (knee, shoulder, etc.)

• Tumors or abnormalities in organs (liver, uterus, kidneys, etc.)

• Heart conditions like cardiomyopathy or valve disease

• Cancer screening (Whole Body MRI)

Types of MRI Scans

Here are some common types of MRI scans:

• MRI Brain – For headaches, seizures, stroke, tumors

• MRI Spine (Cervical/Lumbar/Thoracic) – For back pain, slipped disc

• MRI Joints (Knee, Shoulder, etc.) – For ligament tears, arthritis

• MRI Abdomen & Pelvis – For liver, uterus, kidneys, and more

• Cardiac MRI – For heart structure and function

• Whole Body MRI – For full-body cancer or disease screening

Some scans may also require contrast dye to highlight specific areas more clearly.

How is the Procedure Done?

• You’ll be asked to lie on a flat table that slides into the MRI machine.

• You must stay still during the scan. The machine makes loud sounds, so you may be given earplugs.

• The scan takes 15 to 60 minutes, depending on the body part being examined.

• It is completely painless, though people with claustrophobia may find it a little uncomfortable.

How Much Does an MRI Scan Cost?

The cost of an MRI scan can vary based on:

• The body part being scanned

• Whether contrast is used

• The diagnostic centre location

• Machine type (1.5T or 3T)

On average, MRI scan prices in India range from ₹999 to ₹10,000+, depending on the type. But don’t worry — CareBox can help you save money and time.
