| STIR-TR |
My understanding with Stir is to have longer TR and shorter TE than a normal T2 sequence. Ive also wondered this question and have not found a definite answer as I guess it could vary from manufacturer to manufacturer?
Im on a Siemens Avanto 1.5T, and typically our STIR sequence ranges from:
TR = 4000 - 10,000ms (I try not to go beyond 7,000)
TE = 20 - 40ms
...obviously you can adjust values for different outcomes depending what you are trying to identify.

| Brain T2FS postcontrast |
Gadolinium relaxation times are too short for T2 weighted imaging, so T2 weighted is not tipically performed after contrast (unless used as a delay to give contrast time to peak before T1 FS is obtained).
Also I have never worked at any facility that uses T2 fat sat imaging on the brain. Not a whole lot of fat in the brain region!
FLAIR imaging is the norm...but I could stand corrected.

installing cameras in MRI magnet rooms is a good option , it helps you to keep a track of the patients without putting in much effort.

| ARMRIT in California? |
Facts and performance do support the indisputable fact that ARMRIT professionals have a greater depth of study and assessment of their technique. ARRT techs are grounded in the modality involving radiation. Cross-training is never the same as dedicated didactic and hands on training with the longest externship vis-a-vis all other modalities...and that is ARMRIT.
California is recognizing ARMRIT. Maybe not at the rate it deserves, especially in hospitals. But it is progressing. ARRT has had a monopoly as a registry. Ultrasound was correct in setting up its own registry. ARMRIT is exercising that right as well; as well it should considering it is a non-ionizing modality to begin with. Several times I have come across ARRT techs who cross-trained for MRI and continually demonstrate "button-pushing", time-cutting habits. I have come across ARRT techs who are employed and doing CT work who are not even certified to do CT!!
The scope of ARRT is wide and the medical system is too privatized to monitor abuses of ARRT techs practicing as non-certified CT or MRI personnel under the umbrella of another certified employee. This is a major loophole that is absolutely doing a great disservice to patients and misrepresenting imaging professionals across the board.
And to those who have stated that ARMRIT is taking away jobs from ARRT.....well, if the qualifications fit the position, then what is the issue with the more qualified, better trained professional being offered the position?
Facilities are recognizing the value of an MRI professional with dedicated training. I was offered a staff technologist position before I even took my boards; the first time in this company's history to employ ARMRIT over ARRT.
During my first 3 months as an employed MRI technologist, I quickly recognized several inefficiencies within many existing protocols used daily at the facility for which I worked. I could not understand how for so long before I started work there, that these inaccurate and unrefined sequences could not have been addressed. Well, an ARRT tech, cross-trained in MRI wrote them.
No disrespect to ARRT. This is not a critique but an observation of the disparity of the domination of ARRT as a registry for modalities it should not have jurisdiction over.
