But it's not clear that Reince is, in fact, his given name. His name sometimes appears as Reince R. Priebus, and other times as Reinhold R. Priebus. Fred Priebus, the family patriarch, came to the United States near the turn of the 20 th century.
Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan.
An MRI system requires helium to keep its magnet cool, especially when imaging a patient, and continues to consume helium to remain cool when the magnet is idling. An MRI system must be cooled to 4.2 K, or -452Â° F, and liquid helium is the most effective way to sufficiently cool the magnet to that temperature.
