In the spoke-interleaved multislice acquisition scheme, the RF repetition time increases for any given slice compared to a single-slice measurement (2).
An axial EPI-DWI sequence was performed with the following parameters (repetition time, 1500 ms; echo time, 77 ms, 119x128 matrix, field of view of 250x250 mm (pixel size, 2.10x1.95 mm), six excitations, and section thickness of 5 mm with an intersection gap of 1 mm).
Pelvik MRG teknigi: Aksiyal T1A FSE (repetition time [TR]: 780 msec., echo time [TE]: 8 msec., matriks: 320x224, FOV:400x400mm, NEX: 2, FA: 90[degrees], kesit kalinligi: 4mm).
Comparison among conventional spin echo (CSE), fast spin echo (FSE) and fluid-attenuated inversion recovery (FLAIR) was made to investigate the performance of each pulse sequence with the variation of important pulse sequence parameters such as repetition time (TR) and echo time (TE).
is the relative component of power additional losses due to the variable component of the instantaneous power of the three-phase ESS, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is the relative mean-square value of the variable active power component calculated in the repetition time period;
Repetition time ([T.sub.R])=100, 250, 500, 1000, 2000 and 4000 ms, echo time ([T.sub.E])=15 ms, number of excitations (NEX)=3, matrix size=512x384, pixel band width=130, slice thickness=2.5 mm, number of echoes (NE)=1 and field of view=25 cm.

The participants recommended the construction of a series of dams which would be designed for a repetition time of 200 years and a level of 149mm of rainwater," he said.
