Abstract:Korkeaintensiteettinen fokusoitu ultraääni (engl. high-intensity focused ultrasound, ts. HIFU) on yleistyvä terapeuttinen tekniikka, jolla voidaan lämmittää kudosta paikallisesti ja ei-invasiivisesti ihon läpi. Kudoksen lämmittäminen esimerkiksi 57 °C:seen aiheuttaa nopean koagulatiivisen nekroosin. HIFU-lämmitystä voidaan käyttää myös hypertermiaan, jossa kudoksia ylläpidetään (60 min) kohotetussa lämpötilassa (40 – 45 °C). Hypertermia tehostaa muiden terapiamuotojen, kuten sädehoidon ja kemoterapian tehoa. Magneettiresonanssikuvauksen (engl. magnetic resonance imaging, ts. MRI) käyttäminen HIFU-terapian ohjaukseen (engl. MRI-guided HIFU, ts. MR-HIFU) mahdollistaa hoidon kohdennuksen, reaaliaikaisen lämpötilan seurannan hoidon aikana sekä hoidon tehon arvioinnin hoidon jälkeen. |
