| ARMRIT to ARRT pathway - - - HELP |
Kevin Patana, in 2008, asserts that ARMRIT is "not misleading people," which is technically true. There may be imaging centers in one of the regions he mentions (MN) who are hiring ARMRIT certified techs. If anyone who browses this forum is able to demonstrate even one center for which that is true, it would come as a breath of fresh air. MRI School of Minnesota is one program in the Twin Cities area turning out ARMRIT certified techs. Despite hopeful attempts by these graduates, nearly all of us have not found jobs in the field of MRI. Center For Diagnostic Imaging (CDI), St. Paul Radiology, and Regions Hospital have all submitted in writing that they are not considering ARMRIT certification adequate for hire at their centers. One reason they cite is that their techs need to be (RT) in order to be "multi-modality." During my interview with St. Paul Radiology recently, I was courteously informed that I could not be considered a "tech" in the sense they were using in their job description. Scant experience with venipuncture, total unfamiliarity with MRI School Of MN and ARMRIT, and the need for multi-modality techs were the stated reasons in my face-to-face meeting with them.rnOn a positive note, ARMRIT techs are being hired somewhere--and one graduate of the school who was already employed at an imaging center was promoted to MRI tech, although this tech claimed to be "constantly challenged about [his/her] certification" and aptitude in the field. rnOne question leveled to me in my interview at St. Paul Radiology was, "Why didn't you go to Century/Argosy? (The established ARRT diploma vendors in our area.) I found myself ill-prepared to defend the ARMRIT, only referring to ACR certification, which elicited blinking stares. rnOthers have sought to supplement their ARMRIT certification with local X-ray certificate add-ons.rnWe hope that with further education of the public and local imaging centers, techs may 'break in' to the field, making the ARMRIT certificate more recognized and legitimized. At present, however, it serves as a $16,000 rectangle of parchment with one side blank for a grocery list.

If some of the system are signal starved, it's most likely not due to gradient field strength and speed, but it can be related to that. Like everything else in MRI, it's complex and interdependent.
You're best advised to talk with the apps specialist from the systems that are under-performing, and learn from them what the bandwidth is, and also check the shim. Is the fat suppression OK, but the signal weak, or is the suppression bad also? Do you get a graphic output of the linear (gradient)shim corrrection on the various systems?
It is well worth the money that they might charge, if it comes to that, in order to optimize the use of the systems and for your own education. If the apps person does not know why the other machine works so well, there should be someone higher up in the organization who can shed some light on your question.

Can someone tell me what kind of luck they have had rendering MRIs to 3D. And if there are problems what do you have to do (like no gaps between slices) to get a good quality picture.

I assume that you mean a t2 fat suppressed sequence. Differing gradient strengths have only an indirect effect on these images. The fat saturation sequences require additional pulses which take time to execute; stronger gradient systems can execute these pulses faster.
If you see different results, it can be caused by a number of factors; if you can describe the differences, that would be helpful. Generally speaking, the quality of the magnet homogeneity makes a big difference. If the small FOV scans (wrist) look different from magnet to magnet, that's probably not the cause.
You should ask your MRI applications specialist about this, and pay attention to the TE and bandwidth. Are the FOV and number of steps the same?

I don't know if you are still interested in purchasing imaginged, but I just wanted to share my experience. I just passed my MRI boards and I prepared for it by reading MRI in Practice and viewing the imagingeded videos. They really complimented each other. The book is very thorough and technical and the videos put it all into everyday language. For me it was helpful to have someone explain many of the concepts. Candi is a great teacher and made it easy to understand...well almost easy..it is MRI afterall! Hope this helps:)
