ECHO Time for a big pay debate NEWS of the bumper pay increase given to the vice chancellor of the cash-strapped Liverpool Hope University will shock many Merseysiders - not least those lecturers and admin workers fighting to save their own jobs.
Parameters include a long echo time (TE) of approximately 140 msec and a long TR of approximately 10,000 msec or more to provide high sensitivity to T2 differences.[3] The TR selected is three to four times longer than the T1 value of cerebral spinal fluid to effectively nullify the CSF signal.
By strategically acquiring images at specific echo time (TE) values, two separate images can be acquired in which water and fat signals are located in-phase and out-of-phase, respectively.
