MRI Machines

MRI stands for Magnetic Resonance Imaging. It is a medical imaging technique used to visualize internal structures of the body in detail. MRI machines use strong magnetic fields and radio waves to generate images of the body's organs and tissues.

How MRI Machines Work

When a patient is placed inside the MRI machine, the hydrogen atoms in their body align with the magnetic field. Radio waves are then used to temporarily disrupt this alignment. As the hydrogen atoms realign with the magnetic field, they emit signals that are detected by the MRI machine and used to create detailed images of the internal structures of the body.

Uses of MRI Machines

MRI machines are used to diagnose a wide range of conditions and injuries, including but not limited to:

• Brain and spinal cord injuries
• Tumors and cysts
• Joint and musculoskeletal disorders
• Heart and blood vessel problems
• Breast cancer
• Liver and other abdominal diseases

Preparing for an MRI

Prior to undergoing an MRI scan, patients may need to follow certain preparations, such as avoiding eating or drinking for a period of time, removing metal objects from their body, and informing the technologist of any medical conditions or implanted devices.
