The Application of Steady-State Free Precession to the Study of Very Slow Fluid Flow

Magn Reson Med. 1986 Feb;3(1):140-5. doi: 10.1002/mrm.1910030121.

Abstract

An NMR imaging technique sensitive to slow flow (approximately 1 mm/s) using a conventional imaging gradient strength (0.025 mT/cm) is described. Two projections with different spatial magnetic periodicity (determined by the SSFP pulse interval), and thus with different flow sensitivities, are subtracted to give signal from flows in a velocity window.
