WebBalanced steady-state free precession (balanced-SSFP) was used for spinal imaging in the 1980s and 1990s but was thereafter rejected in favor of FSE, due to severe susceptibility artifacts at the bone-tissue and bone-fluid interfaces in the spine, which restricted its use to low spatial–resolution applications (primarily rapid localizers). ... number to call and listen to musicSteady-state free precession MRI (SSFP) is a type of gradient echo MRI pulse sequence in which a steady, residual transverse magnetization (M xy) is maintained between successive cycles. The sequence is noted for its superiority in dynamic/cine assessment of cardiac function.
