Top imaging centers in the U.S. by MRI procedure volume

Medical imaging is a cornerstone of modern medicine. Key to the delivery of this technology are imaging centers. These centers – staffed by radiologists and medical imaging technologists – specialize in capturing and reading images through various modalities, from X-ray and ultrasound to CT scans and MRI scans.

Below, we’ve compiled a list of 20 imaging centers in the U.S. ranked by percentage of MRI procedures in 2022. MRI is a non-invasive imaging technology that uses a powerful magnet and radio waves to create detailed 3-D images of organs, tissues, and the skeletal system for disease diagnosis and treatment monitoring.

What are the top imaging centers in the U.S. for MRI?

As of April 2023, Definitive Healthcare tracks more than 18,000 imaging centers across the U.S. Among these, Vital Imaging in Miami, Florida is the top imaging center in the U.S. based on MRI procedure volume, with 2.0% of total MRI procedures in 2022. Vital Imaging provides outpatient multimodality medical diagnostic imaging in the Miami-Dade area. Vital Imaging is followed by Austin Radiological Association in San Marcos, Texas (2.0%) and Diagnostic Imaging Centers PA in Overland Park, Kansas (1.5%).

What is magnetic resonance imaging (MRI)?

Magnetic resonance imaging (MRI) is a diagnostic imaging technology that uses a powerful magnetic field and radio waves to produce three-dimensional anatomical images. These images are read and reviewed by radiologists on a computer monitor to detect illnesses and injuries, including tumors and infections.

As a non-invasive imaging technique that does not use ionizing radiation, MRI is a safe and effective way to diagnose and monitor a wide range of medical conditions, from neurological disorders and musculoskeletal injuries to cardiovascular disease and cancer. It’s particularly useful for imaging soft tissues, such as the brain, spinal cord, and organs, which can be difficult to see with other imaging techniques.

MRI, including functional MRI (fMRI), is also used in research to study the structure and function of the brain and other organs. fMRI is a specialized form of MRI that measures changes in blood flow in the brain in response to neural activity. It can be used to understand brain function and map neural activity in real-time.

How does an MRI work?

During an MRI scan, a patient lies on a table that slides into a cylindrical chamber. The MRI machine then creates a strong magnetic field, which causes the protons in the body’s cells to align with the magnetic field. Radio waves are then sent into the body, which causes the protons to emit signals that are detected by the MRI machine. A computer uses these signals to create detailed anatomical images.
