    Nope. It's done by urologists. Also, it is not FDA-approved to be performed in this country for the management of prostate cancer, so urologists have to fly down to the carribean to do it.

    It's also being explored for treatment of uterine fibroids by IR, but not here in the US. It's also being explored as a tool for tumor ablation, which would be in addition to the RF ablation that IR already does.

    If you're curious about more you can check out the Focused Ultrasound Surgery Foundation.

    The Radiation Oncology department at UVA performs MRI focused ultrasound to treat cancer and has federal funding to investigate this technology.

    I thought HIFU was FDA cleared for uterine fibroids.

    Not last time I was at a conference dealing with it, but admittedly that was a little while ago now. Back then the MR guided HIFU was being used in Europe but not here. Perhaps it is now approved?

    Edit to add: So I looked it up and it seems that the Exablate was approved for MR guided HIFU for uterine fibroids back in 2004.

    Here is some more information about HIFU:

    Based on what's I've seen of these machines it seems like the administration could easily fall under the scope of practice of radiation oncology. The planning software is similar, and an understanding of tumor volume and dosing is also required. It will be interesting to see where it goes over the next decade, but it sure seems to me that rad oncs should attempt to be the ones to administer it.

    Certainly sounds like "therapeutic radiology" to me :p

    Sorry to resurrect an older thread, but I was wondering how HIFU treatments were evolving in the clinical world. There were a couple of Rad Onc programs I interviewed at last year (forget which ones though) that made some mention of this modality in passing... Are Rad Onc departments yet trying to get into this line of "therapeutic radiology"?

    No mention of the amount of F/U in the study, but most of the endpoints in the abstract appear to measured at 12 months. Definitely more F/U needed than that for something like localized prostate CA
