Patient 13. a, b Axial and Sagittal T2-weighted MR image showing a bone metastasis of the tibial diaphysis in front of the transducer. c Axial T1-weighted fat-suppressed with contrast MR image showing thermal destruction and necrosis inside the lesion. d Screen capture during sonication showing the thermal dose deposit (hollow arrowhead) inside the diaphysis. Thermal monitoring is performed using a map (empty star) and a graph (star). Temperature monitoring (star) shows a mean temperature of 91 °C at the end of this sonication
