What is an MRI?

Magnetic resonance imaging, also known as an MRI, uses a combination of magnetism, radio waves and computer processing to create detailed images of nearly every body part and internal structure - from bones and joints to vital organs and tiny blood vessels in the brain.

Unlike imaging techniques based on x-ray, with MRI there's no exposure to radiation. It is among the safest and most versatile of imaging methods. Since its introduction for medical purposes in the 1970s, advances in MRI technology have greatly improved image quality, speed and convenience for patients, while giving physicians a safe and versatile tool for screening, diagnosing, surgical planning, treatment and reconstruction.

How does an MRI work?

MRI scanners vary in size and configuration, but all operate on the sample principle. During an MRI scan, the patient lies on a flat table in a short, tunnel-like structure that houses a powerful magnet. The combination of magnetic field and radio waves temporarily interacts at the subatomic level with the water molecules contained within organ tissues. The scanner detects the energy created by this interaction and a computer reconstructs the information into images visible on a monitor.

MRI systems at Florida Hospital

Florida Hospital has several types of MRI systems, including 3T, 1.5T and open systems. The state-of-the-art 3T MRI systems provide exceptional anatomic detail and are particularly useful for diagnostic tests and procedures requiring the high resolution. Our highly-skilled radiologists weigh all factors to choose the right system for each individual to ensure the best outcome for each patient.
