Fast low angle shot magnetic resonance imaging (FLASH MRI) is a particular sequence of magnetic resonance imaging. It is a gradient echo sequence which combines a low-flip angle radio-frequency excitation of the nuclear magnetic resonance signal (recorded as a spatially encoded gradient echo) with a rapid repetition time. It is the generic form of steady-state free precession imaging. Using only the above description and what you know about the world, "FLASH comes from the light emitted with an MRI." is definitely correct, incorrect, or inconclusive?
