New diagnostic frontiers for MR imaging

“Here, in our paper, we clearly show that chronic inflammation is relevant to disability accumulation and not completely targeted by current approved treatments for MS,” said Dr. Martina Absinta, post-doctoral fellow who lead these studies while working at the NIH's National Institute of Neurological Disorders and Stroke. “As direct consequence, we now think that new approaches and new treatment trials are needed to limit this type of brain inflammation in MS.”

The one caveat is that 7T MR is rather expensive for large-scale deployment. Also, there needs to be further standardization and optimization of protocols so that wider clinical use can become a possibility.

“Several of the fundamental components, especially the magnet itself, are simply more expensive than at lower field strengths,” said Mainero. “The question is how much the cost of these components will decrease over time, and how much their costs contribute to overall scanner costs.”

She added that this will depend largely on novel technological developments as well as market demand. Currently, Siemens Healthineers offers the only FDA-approved 7T MR scanner, but the cost will likely drop if more companies enter the market.

“If there is clinical demand for 7T magnets and the number of units ordered goes up, that will no doubt allow Siemens to bring costs down,” said Mainero. “Competition from other vendors also will help with that.”
