MRI registry equations
Take 1.006 - 1.000T or (1.0) this equals 0.006, or (6mT) then take 6 divided by 0.5 (which is your distance along the positive z-direction and this will give you the answer of 12. (Strength of the magnetic field divided ny the distance from the center of the magnet) My suggestion for you is get the new "MRI in Practice" not the green book but the new one with the multi-colors on the front of it (3rd edition) Explains everything and it is fun to read. I have to take mine too in September through ARRT. Just don't psyc yourself out.

MRI registry equations
Subtract the B0 field from the 1.006T and then divide the resulting 6mT by 0.5m.

Hope this helps to understand.

MRI registry equations
I'm studying for the registry with the help of the MIC registry review program. I think my mind has turned to mush. I can not figure out the answer to this question or find an equation to help me. Is there anyone out there who can help?!!
"In an ideal 1.0T magnet with perfect homogeneity, if a proton experiences a magnetic field of 1.006T and is positioned 0.5 meter along the positive z-direction and centered along the x and y directions, the z-gradient amplitude is________mT/m."

MRI Technologist advancement opportunities
The "two cents" you need are to be thankful for your MRI certification, without which you wouldn't even have had the opportunity to work as an MRI tech and clinical instructor. And knowing the economic situation you still have the leisure to think the "grass is greener on the other side"? Your post tells more about your self-defeating attitude rather than substantiating facts.

I have known several ARMRIT certified techs who got job interviews and even jobs at hospitals. How you present yourself in your cover letter and resume are a BIG factor. In certain states where most ARRT techs are cross-trained but not registry eligible in MRI, there is a serious shortage of even ARRT(MR) certified techs.

Just ask the ARRT techs out there if they're getting any better job opportunities these days, even in hospitals. Many hospitals still need dedicated MRI techs and may need to be updated about the ACR's acceptance of ARMRIT certification. So get out there, trust your education and certification, and educate employers that ARMRIT certification is ACR approved and meets Medicare certification requirements in an increasing number of states nationwide.

To update your skills as an MRI tech, visit the continuing ed links at http://www.armrit.org/links.htm. The ARRT recommends similar resources for its certified MR techs.

Finally, if you're interested in a little math: If you were at your current job for at least 6 months, this would have paid off your tuition for the certification you achieved. Any job after that is to your profit for the rest of your life, and the knowledge you gained which you are using can never be taken away from you.

CME for MR
Hi,

I need to complete my CME units for my ARMRIT renewal for the first time. Many among you have already done this a number of times so please tell me a quick way to do this; if possible.

Thank you very much.
