A METHOD OF MAGNETIC RESONANCE FOCUSED SURGICAL AND THERAPEUTIC ULTRASOUND

摘要

A novel method of magnetic resonance focused surgical ultrasound by administering to a patient a magnetic resonance imaging (MRI) contrast medium comprising gas filled vesicles, then scanning the patient with MRI techniques, and then applying ultrasound to effect surgery. These methods may also use an MRI contrast medium comprising gaseous precursor filled vesicles which undergo a phase transition from a liquid to gas in vivo after administration. Additionally, the MRI contrast medium may comprise a therapeutic compound.
