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/

Dear Dr.Dan McGuan;
I’m Kareem Badr from Egypt, Cairo University, faculty of Engineering Systems and biomedical Engineering department.
Actually I have to make a technical report about MRI and really I need your help, so could please help me!
I want to ask if the MRI units are specialized for certain applications only, i.e. is Cardiac MRI
used for cardiac applications only?
If yes, could you please tell me all the applications and the units used
For example
Angiography MRI
Cardiac MRI
.
.
.
etc
Thanks so much, and sorry for the long mail
Waiting for your reply
Kareem Badr

Hello to all my fellow MR Technologists and / or students:
I have a few questions that I would greatly appreciate if someone could help me answer. The dead line is THIS Friday 25th 1000AM morning so please reply STAT
Please e mail me at USMARINE2TIM2@YAHOO.COM
1. . Breath hold duration of less than _________are
recommended when dealing with MR Arenal artery
scan?
a. 30sec
b. 25sec
c. 18sec
d. 8
2. . In renal angiography, what anatomical
landmark does the 3d slab need to cover just
anterior to?
a. Adrenal glands
b. Hepatic vein
c. Portal vein
d. Abdominal aorta
3. .What makes MRI a better choice than DSA for evaluation of a bilateral renal artery stenoses at the orgins of the renal arteries?
a. It is a noisier examination
b. The contrast used is less nephrotoxic than DSA
contrast
c. MRI has higher special resolution than DSA
4. Signal loss will result when further maturation of the clot produces which one of the following?
a. methemoglobin
b. hemosiderin
c. phagocytosis.
d. hemoglobin
5. .For cine gradient echo imaging with true FISP, which of the following statements is TRUE?
a. .images have better image contrast and acquisitions are faster than conventional cine gradient echo imaging
b. cine true FISP images can be performed on any MRI unit
c. to make true FISD images, intravenous gadolinium contrast is needed
d. .true FISP images cannot be used for breath- hold acquisitions because the sequence is too slow
6. Which one of the following statements is NOT
true about phase contrast imaging?
a. .phase contrast imaging is useful for measuring blood flow
b. .phase contrast images are ECG gated
c. .phase contrast images can be performed on most
scanners with cardiac imaging capabilities
d. phase contrast images required
intravenous gadolinium contrast
Thank you so much

| Head Coil |
A researcher who uses our system got a post card from a company:
http://www.insightneuroimaging.com/
He asked me if I have ever heard of them, and I thought I saw them at ISMRM but I don’t remember. Their head coil looks like more of an fMRI coil, but the lack of material in front of the face looks really nice for patients.

I have a colleague who wants to use our 3T for an fMRI experiment and is looking for a good head coil for this. Any good suggestions?
Thanks
