We're relatively certain that if you own/operate an MRI (or a balloon stand, for that matter) you are well aware that there is a helium shortage. The main providers of helium (Praxair and AirProducts) have limited supplies and prices have gone up.
But, you're under a service agreement that covers helium for your MRI so you have nothing to worry about, right? Think again! Even though you are still under a service agreement there are still a few things that you need to be aware of.
