vibe sequences in neuro mri?
I am trying to cut down on time and have read a few articles that talk about mprage and vibe imaging but I am wondering if I can use them for post contrast imaging instead of t 1 sequence on my brain and spine studies. Anyone have any experience or comments about that?

3T imaging parameters
Hi
Am looking for the ranges of acceptable TR and TE's for standard spin echo and gradient echo sequences on a 3T.
Does anyone know these or tell me where I can find this info?

Black Blood MRA
The black blood effect is a natural high contrast between blood and myocardium caused by the flow void of blood. Black blood techniques are for example used to demonstrate fatty infiltration of the right ventricular wall with right ventricular dysplasia. Black blood MRA is usual based on fast spin echo or inversion recovery sequences and seldom used as cine imaging. The advantage of this type of sequence consists of being less sensitive to respiratory and cardiac motion. Bright blood cine imaging is the standard method, but there are manufacturer with different techniques, e.g. Toshiba has a black blood cine technique.
