DWI of the prostate
In need of a protocol for the prostate. Our system is a 1.5 GE Signa Excite 12.0 software.
Under the diffusion options screen the only B-value options are 1000,1500, and 2000.
Should Dual Spin Echo option be selected ?
Main question relates to post processing of the DWI to ADC. Under Functool, what is a good threshold # to choose ?

How does TE affect DWI acquisition?
Hi folk! Just a breath question: how does TE affect conventional sequence (single shot SE-EPI) for DWI acquisition? In particular, how would two acquisitions differ from each other if acquired with TE=90/106ms respectively (being equal all the other parameters, i.e. TR=11s, same FOV, …)? Thanks for any opinion you will give me. Danilo.

bandwidth
Are there differences in the bandwidth numbers as to how it is designated from let's say GE and Toshiba?

Receiver Bandwidth
Can someone give me the calculation for finding the receiver bandwidth value. I can't seem to find this anywhere. I swear that I have seen it before.
