Coincidentally, exactly one year later, on 14 January 1973, Flash would fill New York's Philharmonic Hall. There is some controversy over whether fellow ex-Yes member, keyboardist Tony Kaye, who appeared on the first Flash album, was actually an "official" member of the group, or merely a g…
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 short repetition time. It is the generic form of steady-state free precession imaging.
