Pediatric Sarcomas Are Targetable by MR‐Guided High Intensity Focused Ultrasound (MR‐HIFU): Anatomical Distribution and Radiological Characteristics

Despite intensive therapy, children with metastatic and recurrent sarcoma or neuroblastoma have a poor prognosis. Magnetic resonance guided high intensity focused ultrasound (MR‐HIFU) is a noninvasive technique allowing the delivery of targeted ultrasound energy under MR imaging guidance. MR‐HIFU may be used to ablate tumors without ionizing radiation or target chemotherapy using hyperthermia. Here, we evaluated the anatomic locations of tumors to assess the technical feasibility of MR‐HIFU therapy for children with solid tumors.
