| 6-1.5T MAGNETS, DIFFERING GRADIENTS |
Thank you for your logical advice. Just spoke with GE apps. "No amount of messing with MR parameters can compensate for weak gradients. Increased gradient strength=decreased echo spacing=less blurring". Coincidently, my DO just emailed me asking what the gradient strength is on the magnet the RADs are complaining about.Just MAYBE they'll upgrade it. I need to visit our sites.The only way I have to check other sites' parameters is importing exams from PACS to my modality console. Tedious, but telling. Again, thankyou for all the help.

We maintain a lot of magnets. The leading cause of image quality problems is applications related. Nobody can possibly know all the nuances of pulse sequences by various vendors, software levels, etc. I've heard many times that a certain machine is no good, when in fact the sequences are inefficiently set up. Look there first.
Usually the techs welcome good training. If they don't want to be trained, then you have a problem, but it sounds like this issue is caused by other factors.
If there are differences in baseline quality between the machines, then compensate for that by other means. Signal starvation is easily remedied; keep the quality as consistent as you can and let time be the variable, if it comes down to that.

Thanks so much for the input. NOBODY in my group seems to have a handle on why images vary in quality from 8 different magnets. I'm being pressed to take position of imaging specialist and thru my own research we have gradient strengths from 50 slew rate up to 120. Radiologists complain neuro stinks on the 50 slew rate 1.5T magnet and it is the most pounded on magnet in our group doing hospital inpatients. So many variables including tech expertise.

I don't know if you are still interested in purchasing imaginged, but I just wanted to share my experience. I just passed my MRI boards and I prepared for it by reading MRI in Practice and viewing the imagingeded videos. They really complimented each other. The book is very thorough and technical and the videos put it all into everyday language. For me it was helpful to have someone explain many of the concepts. Candi is a great teacher and made it easy to understand...well almost easy..it is MRI afterall! Hope this helps:)

| please help me for find user manual siemens avento |
i agree, that you should try to contact siemens directly. if they cannot help you i have an extra copy that i might be able to sent you for a small fee. based on my experience,the manuals really are NOT much help as, performing the required actions needed to complete scans are not fully outlined in the manuals, that usally comes from applications training from the manufacturer. it sounds like you purchased a used system with no applications support. siemens systems are fantastic mri scanners. but you are going to need applications help. i can offer assistance in this area if you would like . i am a chief mri technologist here in ny, and have 23 years mri scanning experience.i have 5 years siemens avanto expertise, performing body, msk, neuro, angio and breast mri and biopsy experience. you can contact me at my email mcl1956m@aol.com
