ABSTRACT:
An NMR imaging method of low flow rate fluid by measuring a time-reversed FID signal in a steady state free precession (SSFP) state comprises the steps of imaging in a dephase sequence, a rephase sequence or both of them, and processing the resulting image data by a maximum intensity projection method, a minimum intensity projection method or an image subtraction method to extract image data of fluid.
