1.What is HIFU?

HIFU (high-Intensity Focused Ultrasound) (sometimes FUS or HIFUS) is a highly precise medical procedure using high-intensity focused ultrasound medical device to heat and destroy pathogenic tissue rapidly. It is one modality of therapeutic ultrasound, and, although it induces hyperthermia, it should not be confused with this technique, which heats much less rapidly and to much lower therapeutic temperatures (in general < 45°C).

2.What are MRgFUS and USgFUS?
HIFU is under ultrasonography or computerized MRI. When MRI is used it is sometimes called Magnetic Resonance-guided Focused Ultrasound, often shortened to MRgFUS. When ultrasonography is used it is sometimes called Ultrasound-guided Focused Ultrasound, often shortened to USgFUS. 
3.What are HIFU’s advantages over other techniques?
High Intensity Focused Ultrasound is often considered a promising technology within the non-invasive or minimally invasive therapy segments of medical technology. HIFU’s capacity to generate in-depth precise tissue necrosis using an external applicator, with no effect on the surrounding structures, is unique. The history of using therapeutic ultrasound dates back to early in the 20th century. Technology has continually improved and additional clinical applications, both diagnostic and therapeutic, have become an integral part of medicine today.
An important difference between HIFU and many other forms of focused energy, such as radiation therapy or radio surgery, is that the passage of ultrasound energy through intervening tissue has no apparent cumulative effect on that tissue.
The absence of cumulative effect of HIFU on the treated tissue means that the treatment can be repeated in case of first HIFU treatment failure or partial treatment of the prostate. As a clean treatment (= non-ionizing) HIFU is also an option to treat prostate cancer recurrence after radiation therapy failure.
4.What are HIFU’s products Clinical Indications?
The benign or malign tumors localized in: liver, kidneys, pancreas, bone, breast, uterus, ENT area, prostate, muscles, adipose tissue.
5.What are HIFU’s Contraindications?
Tumors in organs containing gases (lungs, stomach, small intestine), without contact with the thoracic or abdominal wall.Mediastinal tumors Back bone tumors (partial contraindication, decision of the medical committee)
