| ARMRIT in California? |
Does anybody know the general laws regarding ARMRIT techs and being employed in hospitals? I've noticed that most hospitals don't accept ARMRIT techs for some reason, but the Los Angeles County hospital now accepts the certification as a qualification when hiring for MRI technologists. I don't know if there's a law banning ARMRIT from private hospitals because if the county accepts it, then I'm assuming there isn't a law.
It's pretty frustrating to experience being rejected because you're not ARRT-- even if it's for an MRI position. I can understand if the job requires you work in different modalities other than MRI, but I'm assuming not all hospitals/imaging centers require their MRI techs to do more than MRIs.
I believe that ARMRIT techs are just as qualified to do MRI's as any other certification. ARMRIT techs are actually trained specifically for MRI. ARRT-only techs only need some on-the-job training. They're not required to pass any MRI exams (although they may get ARRT-MRI cert if they wish) or take MRI-specific classes. ARMRIT techs are. I would say that if you compare an ARMRIT tech vs. an ARRT tech who both just graduated and are ready to work, the ARMRIT tech is actually more qualified to do MRIs.
I'm not trying to discredit the non-MRI certified ARRT techs. I'm just trying to lay out the logical reasons why ARMRIT should not be dismissed to do MRIs. I do believe, however, that MRI should go the way of ultrasound, in that it should be considered separate from radiology in the sense that it doesn't use ionizing radiation. This use of totally different technologies and means of acquiring images should be recognized by the hospitals and imaging centers, and should not rule out ARMRIT because of the power of the ARRT lobby.
I believe the universal acceptance of ARMRIT as a respectable certifying body would help hospitals and imaging centers become more competitive and may be able to cut costs because ARMRIT techs may accept less pay just to get their foot in the door and work for a larger company.
If any of you has any information or suggestions on how to get ARMRIT accepted as a qualification to all MRI facilities, please let us all know.
Also, if anybody has any information on how Oregon, Ohio, or West Virginia allowed ARMRIT techs to be board certified, please include it here too.
Thanks!

| Building 3d Volumes from MRI DICOM |
I have a number of MRI and CTs since a bad accident. I am a Mechanical Engineer with an electrical, power and computer background.
I was able to render the CT to 3D using Onis (not sure if you've seen this program), but have been unable to manage it with any of the MRIs.
The MRIs were taken on a Phillips Intera 1.5T
I can render a volume but only (1) of the (3) 2D images are clear before it is rendered and the resulting 3D image is just noise. I've tried various software packages and spent a lot of time with the software. Perhaps I don't have the required image files.
Maybe someone knows the answer.
Thanks,
Bob

Don't have a solid definition, but will give an example. Pituitary study: you can run a dynamic study by using a power injector set for a slow infusion rate of let's say 0.75ml/sec. The scanner is set to run a scan sequence through the PIT (25-35 seconds) and then repeat that sequence usually six times. The dynamic "uptake" and "falloff" of contrast in the PIT is evident.
Hope this helps.

| Technical Specifications |
Hi,
I'm kind of new to MRI technology and am doing a comparison of various MRI equipment. Could somebody give me a brief summary of the technical specifications I should pay special attention to?
E.g. High slew rate is preferable
High transmit power (at least 15kW)
High gradient field strength
Helium usage (in terms of maintenance costs)
Etc.
What other factors play a huge role in differing price?
Thanks in advance

| How to setup a MRI room? + questions |
I'm planning to purchase a used 1.0-1.5T MRI and I had a few questions.
From what I gather, I need a 480V line, correct? The unit 1.5T takes about 150amps. Does it suck all that power 24x7, or when it's on? If not all the time then how much when it's on standby?
What kind of cooling would I need? From what I read a helium? gas setup? What about A/C? how strong would I need?
What about the room. What size does it have to be? does it need any special insulation?
And are there any companies in Europe what can design and build a room for it?
