| How does TE affect DWI acquisition? |
I never tried to shorten only the echo time while keeping all other parameters the same, but I would expect a change in SNR and artifact appearance. I would use parallel imaging methods to get a shortest possible echo time. Parallel imaging provides DWI with shorter echo trains associated with further reduction of the echo and repetition times, which reduces susceptibility effects and also image blurring. Additionally, the shorter echo time may lead to changes in ADC measurement.

Quite possible. Manufactures like their own designations for bandwidth for ??? reasons. GE uses true bandwidth in KHz. Siemens uses Hz/PIXEL. Not sure what Toshiba uses. Contact Toshiba applications for designator and conversion factor.

how can I increase echo spacing without modifying the bandwith in a Siemens Trio?

| MRI Bandwidth and turbo factor relation ? |
then, bandwidth value increase mean "150-->190" correct?
or bandwidth value decrease mean "190-->150" correct?
simense avanto 1.5T is bandwidth figure value
