Sadly, open MR magnets aren't usually as strong as 'traditional' magnets greatly reducing the images resolution. This can be a big problem for neuro and MSK exams. There's hope though: Hitachi Medical has a new 1.2T 'open' magnet. It's better than what I've seen from open magnets, but not spectacular.
.7 Tesla Open MRI's produce very effective and valuable results.
These results are especially apparent during MRI scans in the Stand-Up or Weight-Bearing machines for the most common procedures of scanning necks, backs and knees!
Do a search for "Stand Up MRI" on any major search engine to receive better insight on the value of this new technology.
I am a radiologist. When you sit in my chair reading exams for patients you do notice a difference in quality between a mid-field and high-field magnet. I won't have any neuro exams performed on our 'open' 0.7T magnet secondary to it's inability to image as well as a high-field magnet. I won't have any MRA exams of the abdomen or extremities performed on the mid-field magnet either. SNR is much too low to delineate such fine structures.
my mom got an open mri..the mri machine is music itself.. i was scared of it then i started to get into a groove lol
i had so much fun...but it can also be a bit intimidating :S
