(CPMG) This type of spin echo pulse sequence consisting of a 90° radio frequency pulse followed by an echo train induced by successive 180° pulses and is useful for measuring T2 weighted images. It is a modification of the Carr-Purcell RF pulse sequence, with 90° phase shift in the rotating frame of reference between the 90° pulse and the subsequent 180° pulses in order to reduce accumulating effects of imperfections in the 180° pulses. Suppression of effects of pulse error accumulation can alternatively be achieved by switching phases of the 180° pulses by 180°.

Diffusion Weighted Whole Body Imaging
 
(DWIBS) This diffusion weighted whole body imaging with background signal suppression provides diffusion weighted contrast throughout the body using a single or multi-station background-suppressed diffusion imaging. DWIBS images are comparable with PET images and provide applications from the visualization of nerve roots and brachial plexus to the detection of lesions throughout the body.

Half Fourier Acquisition Single Shot Turbo Spin EchoInfoSheet: - Sequences -

(HASTE) A pulse sequence with data acquisition after an initial preparation pulse for contrast enhancement with the use of a very long echo train (Single shot TSE), whereat each echo is individually phase encoded. This technique is a heavily T2 weighted, high speed sequence with partial Fourier technique, a great sensitivity for fluid detection and a fast acquisition time of about 1 sec per slice. This advantage makes it possible for using breath-hold with excellent motionless MRI, e.g. used for liver and lung imaging.
