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.
How an MRI works. The MRI scan consists of a table that slides into a large cylinder. Inside the cylinder is a magnet that, when operated, creates a powerful magnetic field. Soft tissue contains water molecules and the magnetic field acts upon microscopic substances (called protons) found in water.
