MRI

Magnetic Resonance Imaging (MRI) is a non-invasive medical imaging technique that uses magnetic fields and radio waves to create detailed images of the inside of your body...

What is an MRI (Magnetic Resonance Imaging)?

An MRI is an advanced imaging technology that produces high-resolution, cross-sectional images of organs, tissues, and other structures inside the body.

How It Works:

• MRI uses powerful magnets to align hydrogen atoms in the body.
• Radio waves disrupt this alignment, and the MRI machine captures signals from the atoms as they realign.
• These signals are processed to create detailed images of the scanned area.

Purpose:

To detect abnormalities, monitor treatment progress, or guide surgical planning.

Why is MRI Important?

• Detailed Imaging: Provides superior contrast between soft tissues.
• Non-Invasive: Offers a safe alternative to exploratory surgeries.
• Radiation-Free: Ideal for repeated use in sensitive populations.
• Versatile: Useful in many medical fields.

When is an MRI Recommended?

• Neurological Issues: Strokes, tumors, MS.
• Musculoskeletal: Joint or spine injuries.
• Abdomen: Liver, kidney evaluation.
• Cardiac: Structural and blood flow analysis.
• Cancer: Diagnosis and treatment monitoring.

How is an MRI Performed?

1. Preparation: Remove all metal. Contrast dye may be used.
2. Imaging: Lie still in the MRI machine. It may be noisy.
3. Completion: Return to normal activity after scan.

Uses of MRI

• Brain and Spinal Cord
• Joints and Soft Tissues
• Cardiovascular Health
• Abdominal and Pelvic Organs
• Cancer

Test Results Interpretation

• Normal: No abnormalities found.
• Abnormal: May indicate tumors, infection, degeneration, etc.
• Follow-Up: May include biopsy or other tests.

Normal Range for MRI Findings

• Healthy Brain: No lesions or swelling.
• Spinal MRI: No compression or herniation.
• Abdominal MRI: Organs normal in size and shape.

How to Prepare for an MRI

• Wear metal-free clothing.
• Inform doctor of implants or allergies.
• Follow fasting instructions if needed.
• Discuss sedation options if claustrophobic.

Benefits of MRI

• High-Resolution Imaging
• Non-Invasive and Safe
• Wide Diagnostic Applications
• Real-Time Imaging for Procedures

Limitations of MRI

• Claustrophobia
• Not suitable for all implants
• Longer scan times
• More expensive
