T1 FAT SAT PRE AND POS GADO
The contrast agent causes this difference. Contrast agents reduce the T1 time in tissues where they have accumulated depending on blood flow and vascular permeability. Caused by this, tissues after an application of contrast agents will differ in shortening of the T1 time, and the same imaging parameters result in other image appearance.
Some helpful links for musculoskeletal imaging and Fat Sat:

Hope this helps

Export Raw Data
In our institution we work on a Siemens Magnetom Sympony. My question is: is there a way to export raw data? In order to load .dat files in a in-house written IDL software.

Thanks

Help Please
Dear Mr. Kareem Badr:

I am flattered by your comments and appreciate your interest in our exciting MRI field.

To put a simple answer to your question, "are MRI units specialized for certain applications?" Usually the answer would be no.

Imaging techniques like Cardiac, Angiography, etc. are options that can be purchased on MRI systems. From a purely sales and marketing perspective MRI system are designed with a basic package that can perform the standard MRI imaging techniques. From there, additional packages and options can be added to "upgrade" the capabilities of the scanner.

While there are a few "niche" scanners on the market that are limited to one, or to just a few techniques, for example breast imaging. Most scanners are capable, with enhancements and upgrades, of performing most imaging techniques.

Now with that said, even though all scanners are capable of running most imaging techniques, it is also important to note that some scanners may be better at a particular technique, while maybe not as good at another technique. Personal opinions and biases can create heated debates as to which systems are better for each technique. As with any other modality, there are positives and negatives with all of the scanners.

Finally, to answer your question on applications and the units that can perform the techniques, this would be a long, detailed list. What I would suggest is that you visit the websites of the major MRI manufacturers. All of the information you would need will be at these websites. I have provided website addresses of the major OEM's and additional manufacturers that design and sell MRI systems below:

1) GE Medical: http://www.gehealthcare.com/usen/index.html
2) Siemens Medical: http://www.medical.siemens.com
3) Toshiba Medical: http://medical.toshiba.com/
4) Philips Medical: http://www.medical.philips.com/index.html
5) Hitachi Medical: http://www.hitachimed.com/
6) Fonar: http://www.fonar.com/
7) Aurora Imaging: http://www.auroramri.com/
8) Magnevu: http://www.mri4ra.com/
9) Odin Medical: http://www.odinmed.com/newSite/index.html
10) Millennium: http://www.millennium.ca/medical/medical.html
11) ONI Medical: http://www.onicorp.com/website/index.htm
12) Esaote: http://www.esaote.com/products/MRI/products1.htm
13) DigiMRI: http://www.digimri.com/
14) Bruker: http://www.bruker.de/

Good luck in your research, and once again I appreciate your interest.

Rajani,

If you have appropriate electronics training and experience it is relatively easy to get a job "servicing" MRI. R&D and other jobs are a little more difficult, but all manufacturers are looking for trainees in both their service and developement departments.

Start at the major OEM's websites (GE, Philips, Siemens, Hitachi, Toshiba etc.) and view their "career opportunities." I'm sure you'll find something.

Third party companies are also looking for trainees. Do a search on Google or Yahoo for "MRI Service" and you'll find many sites with job openings.

Good Luck,
Dan McGuan

we have had great success with a Medrad Spectris power injector - peripheral angios can be done using 20mls gad at flow rate of 1ml/sec without venous return.(siemens symphony magnetom 1.5T)
