Abstract
An MR pulse sequence for conducting fat- or water-suppressed multislice MR studies. Saturation prepulses are used less frequently than is conventional practice. Each time at least one saturation prepulse is used to saturate all slices in a group of slices, one line of MR data is acquired from each slice in the group without using any other saturation prepulse.
Claims4
A method of rapidly conducting a fat-suppressed or blood-suppressed two-dimensional multislice MR study of a patient, comprising the following steps:
- a) using at least one saturation prepulse to saturate all of the slices in a group of slices, thereby suppressing the fat or water signal in all such slices in the group;
- b) reading out one line of MR data from each slice in the group, without using any other saturation prepulses until a line of MR data has been read out from each slice in the group;
- and
- c) repeating steps a) and b) above until sufficient MR data has been acquired from all slices in the group.
A method of rapidly conducting a multislice MR study of a patient, in which study the signal from an undesired spectral component has been suppressed, comprising the following steps:
- a) using at least one saturation prepulse to saturate all of the slices in a group of slices, thereby suppressing, in all such slices in the group, the signal from the undesired spectral component;
- b) reading out one line of MR data from each slice in the group, without using any other saturation prepulses until a line of MR data has been read out from each slice in the group;
- and
- c) repeating steps a) and b) above until sufficient MR data has been acquired from all slices in the group.
