Under-powered, under-utilized, and sometimes misunderstood, open MRI systems are often under-appreciated here in the USA and ignored in other “developed” countries.
Many radiologists don’t want to read from open MRIs, governments and insurers don’t want to pay for them, and the appetite for higher and higher powered magnets has, in many cases, relegated the open MRI to a “back-up” role in larger imaging facilities. Whether or not that relegation is deserved, it’s a fact that the demand for low-field open MRI (.2T - .35T) has remained strong in developing countries since this article was last updated in early 2016. So what exactly is it that makes some facilities prize low-field open MRI over closed MRI? We've found a few reasons we'll share here.
