Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
MR imaging uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. The images can then be examined on a computer monitor, printed or copied to CD. MRI does not use ionizing radiation (x-rays).
MR angiography (MRA) is used to examine blood vessels in key areas of the body, including the:
brain
kidneys
pelvis
legs
lungs
heart
neck
abdomen

Ive "googled" the two myself. Im asking what the difference is? How are they using the same machine, same contrast, and getting different results?
