There is work being done in the area but the interesting part is that the MRI isn't only used for its direct imaging but also the ability to use it as a very expensive thermometer[1].
Not every procedure lends well to alternative imaging modality (Brain surgery is one) but ultrasound guided FUS is really where there is potential to increase adoption.

- 1_over_n 7y agoFound a good paper here outlining MR vs US (see table 2). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3064817/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3064817/ The "expensive thermometer" point is interesing. Cant we develop a cheaper one?
- always_swapping 7y agoGood paper, but it focuses on cancer applications but it would be a disservice to not point out the strides that HIFU is making in drug delivery[1], neurosurgery, and neuromodulation[3]. The (un)fortunate point of MRI thermometry is that is not only very effective at reading temperatures, but it can also produce thermal dosage maps that help in characterizing tissue leisioning (the exact response of HIFU ablated tissue is still be debated). On top of that you also get traditional MRI imaging essentially for free.
