| MRI registry equations |
i don't know if it's just me but i feel the questions on the MIC course are way off topic sometimes. when i answer these questions myself, i feel like i know nothing cause the questions IMO are being asked in the "beating around the bush method"
i've been told that the registry is more basic than the questions they ask. pus they cover way too much than the ARRT exam question breakdown.
i'm going to use the black and yellow & lippincott book plus the answered question MIC from here on in.
can anyone who knows of or has taken the registry recently than can clarify this.
any advise or info will be greatly appreciated cause i'm pretty intimitaded by this test and i want it done by the end of this year

| 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.

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."

| 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.
Neeta

| question about resolution in an MRI |
Hello,
I have to hold a lecture about the resolution in MRIs.
My problem is, that I do not really understand if the resolution in an MRI can be compared with the "standard" resolution terms that you learn in physics. For example that the resolution equals 1/the distance of two points that you can see seperately.
Those equations go for optic devices like microscopes, right? Do they also account for an MRI?
And generally, how do you define resolution in an MRI and how can you enhance or change it in the practical use?
It would be great if you could help me. I have been looking for more information on the internet, but I didn't really find websites that answered my questions. Maybe you know some informative and helpful sites?
Thanks.
