Introduction. Focused ultrasound

MR guided focused ultrasound

The joining of high-intensity focused ultrasound with high-resolution MR guidance has created a system that can produce tissue destruction deep within solid organs without any invasion. Accurate targeting and thermal mapping are provided by MRI and allow very accurate deposition of energy in tissues that can be altered in response to near real-time thermal imaging produced by MR so that the var...

Focused ultrasound in ophthalmology

The use of focused ultrasound to obtain diagnostically significant information about the eye goes back to the 1950s. This review describes the historical and technological development of ophthalmic ultrasound and its clinical application and impact. Ultrasound, like light, can be focused, which is crucial for formation of high-resolution, diagnostically useful images. Focused, single-element, m...

Focused ultrasound and immunotherapy

Background/introduction Thermal therapy has tremendous potential to augment the benefits of immunotherapy. The ability of heat to stimulate both general and tumor specific responses, in part through heat shock protein mediated mechanisms has been known for over two decades. Significant challenges persist however in translating these effects into predictable and meaningful clinical responses. Mo...

High intensity focused ultrasound (HIFU).

INTRODUCTION Curative treatments for localized prostate cancer, from least invasive to most invasive, include brachytherapy, cryosurgery, three-dimensional conformal radiation therapy, external beam radiation therapy, and radical prostatectomy. A patient with localized, low risk or intermediate risk prostate cancer who is diagnosed at an early age and receives one of these treatments has only a...
