Abstract

Magnetic Resonance Imaging (MRI) sequences with selective radio frequency pulses and magnetic field gradients combine many well known ‘classical’ non-imaging experimental methods. Early attempts to quantify flow were made using Stejskal’s observation (1), that the phase of the complex NMR signal will be shifted due to movement of the spin system in a magnetic field gradient. Subsequent development of this concept lead to Packer's pulse sequence (2), which succeeded in measuring ‘slow coherent motion’ in the range of pm/s. Packer combined the advantage of small RF-pulse intervals in multiple echo experiments (to reduce diffusion effects) with the accumulation of flow sensitive phase by incorporating a series of additional magnetic gradients.
