3 particular, MRgFUS, which is performed under MRI guidance, is notable because it allows clinicians to monitor the target area while treatment is being performed. However, focused ultrasound therapy does not automatically spread simply because it is new or advanced. Questions such as which conditions are covered by insurance, which patients are eligible, where expensive equipment can be installed, and how trained personnel can be secured all have a major influence on their use. This report looks at focused ultrasound therapy in Japan, the United States, and Germany, and considers both its technical promise and its institutional challenges.1.2 Insurance Coverage: The Range of Covered Conditions is Limited In Japan, some MRgFUS indications have gradually entered the public insurance system. For example, essential tremor and some Parkinson's disease-related tremor have come to be covered under national health insurance. Still, not every use of focused ultrasound therapy is widely available under insurance. Covered indications remain limited, and whether a patient can actually receive the treatment depends on the type of disease, symptom severity, and whether an appropriate medical institution is available. This shows that "having technology" and "making it accessible to everyone" are not the same thing. In medicine, there is strong interest in treating disease while causing as little damage to the body as possible. One of the technologies attracting attention in this context is focused ultrasound therapy. This treatment aims to deliver energy deep inside the body by concentrating ultrasound waves at a single point, without making a large incision on the body surface. It is somewhat similar to how a magnifying glass can focus light into one hot spot. Ultrasound itself passes through the body, but at the focal point, thermal or physical effects can become stronger and may change the targeted tissue. This technology has been used not only for conditions such as uterine fibroids, but also for tremor in essential tremor and some forms of Parkinson's disease. In In Japan, focused ultrasound therapy has attracted attention as one type of "incisionless treatment." In particular, MRgFUS for tremors has increasingly been positioned as a possible option for patients whose symptoms do not respond well to medication.1.1 Technical Features: Why Can It Be Described as "Incisionless"? One major feature of focused ultrasound therapy is that ultrasound is sent from outside the body and concentrated at a specific point inside it. Unlike ordinary surgery with a scalpel, this means treatment may be possible without creating a large wound on the body surface. When combined with MRI, treatment can be performed while confirming the target location and temperature changes. For that reason, more accurate treatment is often expected. This is one reason why the method has been explored in areas such as neurosurgery and gynecology.Chihiro ItoIntroduction: A Medical Technology That Aims to Treat Without IncisionsChapter 1: Japan - A Promising Technology That Is Not Easy to ExpandGraduate School of Tokyo University of Science, JapanHealthcare System Challenges in Focused Ultrasound Therapy: An Analysis of Japan and an International Comparison
