Magnetic resonance imaging or MRI, is primarily a medical imaging technique used in radiology to visualize detailed internal structure and limited function of the body. Stargate Command used MRI's to detect infestation by a Symbiote. When Colonel Everett Young was injured exiting the Stargate on the Destiny, Lt. Tamara Johansen told him he could have internal or concussive injuries and he needed an MRI and a qualified Doctor to read it. (SGU: "Air, Part 2")

| - X-ray technologists require one extra year of courses to become specialized in MRI. These courses can be taken by correspondance or in classroom. There is a clinical component required of this specialization, in which the students are required to spend several hours working regular shifts in an MRI unit to develop experience and apply knowledge. The X-ray technologists are required to question each patient prior to performing the procedure. Questions are designed to determine if patients have any metallic items that can be removed or those that cannot. Also questions are designed to determine if any metal may exist in the eyes from previous jobs or hobbies Because MRI uses an extremely strong magnet, it is important that anyone entering the room remove all metal. Deaths have been recorded around the world from carelessness in MRI suites. Common hospital items such as IV poles that usually accompany patients are not permitted near the magnet. Specialized equipment is required and the patients IV bags must be transferred. References: Bontrager, K.L. & Lampignano, J.P. (2005). Radiographic Positioning and Related Anatomy.

MRI provides much greater contrast between the different soft tissues of the body than computed tomography (CT) does, making it especially useful in neurological (brain), musculoskeletal, cardiovascular, and oncological (cancer) imaging. Unlike CT, it uses no ionizing radiation, but uses a powerful magnetic field to align the nuclear magnetization of (usually) hydrogen atoms in water in the body. Radiofrequency fields are used to systematically alter the alignment of this magnetization, causing the hydrogen nuclei to produce a rotating magnetic field detectable by the scanner. This signal can be manipulated by additional magnetic fields to build up enough information to construct an image of the body. Handheld MRI machines exist in the twenty-sixth century, and Dr. Halsey kept one in her tiny medical field kit she made after fleeing CASTLE Base.

Also comes in a mobile trailer system for those without in-house MRI capabilities. Magnetic resonance imaging relies upon signals derived from water molecules, which comprise between 70% and 80% of the average human brain. This ubiquitous biological molecule has two protons, which by virtue of their positive charge act as small magnets on a subatomic scale. Positioned within the large magnetic field of an MR scanner, typically 30 to 60 thousand times stronger than the magnetic field of the earth, these microscopic magnets collectively produce a tiny net magnetization that can be measured outside of the body and used to generate very high-resolution images that reveal information about water molecules in the brain and their local environment. Protons placed in a magnetic field have the interesting property that they will absorb energy at specific frequencies, and then re-emit the energy at the same frequency. To measure the net magnetization, a coil placed around the head is used to both to generate electromagnetic waves and measure the electromagnetic waves that are emitted from the head in response. Unlike CT, which uses x-rays with very high frequency energy, MRI uses electromagnetic waves in the same portion of the electromagnetic spectrum as broadcast FM radio. MRI is also a tomographic imaging modality, in that it produces two-dimensional images that consist of individual slices of the brain. Images in MRI need not be acquired transaxially, and the table or scanner does not move to cover different slices in the brain. Rather, images can be obtained in any plane through the head by electronically “steering” the plane of the scan. Precise spatial localization is achieved through a process termed gradient encoding. The switching on and off of these magnetic field gradients are the source of the loud clicking and whirring noises that are heard during an MRI scan. While this process requires more time than CT scanning, imaging can be performed relatively rapidly using modern gradient systems. Lastly, a contrast media, or “dyes” are used both in brain CT and MRI to provide another mechanism for modulating image intensity beyond what is possible using intrinsic tissue contrast. The device operates on 60Hz, 480 VAC, 3-phase Delta-Wye, 200 amps power circuit. The maximum allowable line voltage variation is +/- 10 percent (432-528 VAC) and 3-phase balance should be with 2%. The room requires data lines for telephone (RJ11) and work station (RJ45) communications.
