| does the metaloceramic dental crowns are problem for MRI |
hey everyone
I had an MRI (1.5 Tesla) and I have a dental crown and bridge, and metal fillings. I think I have the metal bonding porcelain crowns made with Nickel-Chromium, but it doesn’t matter. You will feel nothing. It doesn’t matter if you have titanium, or anything else. The MRI people are more worried about metal in soft tissue which can move around during the scan. Anything on your teeth or bone is fixed and therefore won’t cause problems. And for the patient, who cares about pain / discomfort, there is none, you’ll experience no sensation at all due to dental work.
Hope this helps

| MRV--Phase contrast question |
What exactly is an MRV sequence on an Hitachi Airis II .3 Tesla?
I realize it has to do with the venus system but if anyone knows anything I sure would appreciate your time and knowledge concerning this.
Also The physician I am working under(Neurologist), he would like to see my MRAs done with a phase encoding protocall? Is there such a thing? I hope someone out there can give me some knowledgable info on this. Thank you Sheila/Georgia :)

| Radio frequency exposure |
If the magnetic field strength (measured in Tesla/Gauss) increases, also the SAR increases. For fields up to 3.0 Tesla, the value of SAR is proportional to the square of the field but at high fields the body becomes increasingly conductive, with the need of increased RF power. The EMF exposure is reduced by the square of the distance.
Hope this will help
