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.
Your body contains millions of hydrogen atoms. When you are in an MRI scanner: 1  A strong magnetic field aligns particles called protons which are within the hydrogen atoms. 2  All the protons line up in parallel to the magnetic field, like tiny magnets. ( 3 Normally the millions of protons all lie in random directions.).
