Magnetic Resonance Imaging (MRI) technologists use non-ionizing radio frequency electromagnetic waves (low-energy electromagnetic waves in conjunction with a magnetic field) to generate image contrast and create a 3-dimensional image of a part of the body. MRI technologists operate MRI and related auxiliary equipment, perform venipuncture and communicate with radiologists, members of the health care team, patients and their families.
MRI technologists work directly with healthy and critically ill inpatients and outpatients of all ages. They must be able to move and lift patients from exam tables to and from MRI scanning rooms, sit at computer consoles in a small, low-lit room and adhere to safety policies working in or near a magnetic field.
To perform/assist with MRI procedures on patients, students must initially undergo the same screening procedures as patients in order to enter the scan room. The MRI scan room contains a region of intense magnetic field. Objects that display any form of ferromagnetism are therefore of particular concern for MRI. Contraindications for entering the MRI scan room include:
- Certain biomedical implants, materials, and devices (e.g., aneurysm clips, brain clips)
- Certain electrically, magnetically and mechanically activated implants and devices (e.g., cardiac pacemakers, cochlear implants)
- Certain metallic foreign objects (e.g., shrapnel, bullets, metal in eyes)
MRI students must be re-screened for MRI safety clearance, should their status change during the academic year, with regard to any potentially hazardous implants, devices, or objects, prior to MRI rotations or observations.
