Glossary Term
Magnetic Resonance Imaging (MRI)
Definition
Magnetic Resonance Imaging (MRI) is a non-invasive medical imaging technique that uses strong magnetic fields, radio waves, and a computer to produce detailed images of the internal structures of the body. It is particularly effective for visualizing soft tissues, such as the brain, muscles, and organs, and does not involve ionizing radiation.
Relevance to the MedTech Industry
MRI plays a critical role in diagnosing and monitoring a wide range of conditions, including neurological disorders, musculoskeletal injuries, cardiovascular diseases, and cancers. Its ability to provide high-resolution images without radiation exposure makes it a preferred modality for many applications.

Key Features of MRI
High-Resolution Imaging: Superior detail for soft tissue visualization compared to other imaging modalities.
Non-Ionizing Radiation: Safe for repeated use as it does not involve X-rays or other ionizing radiation.
Multiplanar Imaging: Ability to capture images in multiple planes (e.g., sagittal, coronal, axial) for comprehensive views.
Contrast Agents: Use of gadolinium-based contrast agents to enhance image clarity in specific areas.
Advanced Techniques: Functional MRI (fMRI) for brain activity mapping and diffusion MRI for visualizing neural pathways.
Related Terms
Functional MRI (fMRI): A specialized MRI technique that measures brain activity by detecting changes in blood flow.
Diffusion-Weighted Imaging (DWI): MRI technique used to identify stroke or other pathologies by visualizing the diffusion of water molecules.
MRI-Compatible Devices: Implants or devices designed to function safely in MRI environments.
Open MRI: An alternative design offering a less confined scanning experience for patients with claustrophobia.
Tesla (T): The unit of measurement for magnetic field strength in MRI machines, typically ranging from 1.5T to 7T for clinical use.
