Treatment of substance abuse and addictive disorders by non-invasive transcranial brain high-intensity focused ultrasound guided and controlled by magnetic resonance imaging or by transcranial non-invasive MRI-guided focused ultrasound surgery. The majority of pathological zones associated with addictions are located in the anterior cingulate cortex, a part of the prefrontal cortex. Localization of the pathological zone will be performed by functional Magnetic Resonance Imaging (fMRI) and Diffusion Tensor imaging (DTI) techniques. The therapy is designed to mitigate or even destroy pathological neuron networks. Absorption of ultrasound waves in the selected focal area will heat and consequently thermally destroy the pathological zone. MR imaging and MR-thermometry allows real-time therapy guidance and ablate targeted tissue without damaging normal structures.
