I just recently found this web site otherwise I would have responded sooner. My suggestion is another web sight. It is loaded with information.
Try medcycolpaedia.com and type in whatever your seaching for. Hope this helps

It depends.
When Centric echo allocation is used you have higher SNR, a low TE, but more image blurring. Very similar to a PD. I prefer an echo train of less than 8 in this case.
When Sequential echo allocation is used you have lower SNR, a higher TE (I prefer less than a TE of 60), but significantly less image blurring. Very similar to a T2 or FLAIR. In this case your echo train length is governed by your TE and image blurring is not usually an issue. Depending on how short of an inter-echo time you can use, and by keeping an eye on the TE, the echo train can be as high as you want.
Hope this helps.

Hi Folks,
As an ARMRIT technologist; the small clinic I work for is concerned about allowing me to contrast patients as a non-ARRT person. In Washington State, it is my understanding that RT's are legally allowed to push contrast and is common practice.
I read that ARRT now accepts MR as a primary pathway to registration, but I am concerned if I am eligible. Any advice there on the side?
It dawned on me that this may be a problem other ARMRIT's. Any tips?
Thanks a bunch!

A test bolus helps to get the delay at which time the CE-MRA sequence has to be started. The sequence needed is a one-slice dynamic fast gradient echo sequence (if possible with fat suppression or subtraction) and a temporal resolution of 0.5 to 1.5 sec. This thick slice is placed over the vessel of interest and the dynamic is started simultaneous with a small (1-2ml) bolus of Gad.
In the follow up you can see at which time the bolus is visible. If it is not clear to differentiate, a ROI measurement will help. The starting time depends on the k-space filling. Around the peak of the highest intensity, the contrast information should be read out (with "centric" at the beginning of the sequence).
Centric k-space filling order means that the central lines of the k-space are filled in the first seconds after starting the scan. Depending on the equipment, there is more than one non-centric order, for example linear, where the central lines are filled in the middle of the scan time.
Hope this helps.
