Since MRI technicians work with the human body, they need to have an understanding of the components of the human body and how they work. A technician will scan a part of the body based a physician's description and must make sure it's the correct image needed. Anatomy and physiology are entry-level classes in any medical program. Every medical class after anatomy and physiology feeds off the knowledge that has been learned from it.
Students are introduced to the basic process of scanning images in the MRI procedures class. The procedures class teaches students how to capture an image of a particular body part. MRIs can produce images of both hard and soft tissues if used correctly, and students learn to operate the machines to scan the desired anatomical feature. Students are taught how prepare patients for the scan by positioning them for the best possible image. Because patients are exposed a strong magnetic field, proper precautions must be taken to protect the equipment and the patients. Jewelry and metal items, for instance, can become dangerous projectiles if not remove from the room.
In a hospital or clinic, communication between physicians and technicians leaves great room for mistakes. Setting a standard vocabulary reduces the chances of misinterpreting medical charts and orders. A medical terminology class teaches names of equipment, procedures and tests to place every employee on the same level, reducing the chances of error.
Even though physicians make the final diagnosis of an MRI image, technicians still check their work once the test is completed. Students are taught what to look for on an MRI image. In the MRI pathology class, students learn to compare normal and abnormal MRI images to get familiar with what they will see in a medical setting. Checking images beforehand ensures that the physician can make the proper diagnosis and the correct image has been captured to prevent the need for performing another MRI.
