Abstract:
Two cases are presented in which spectral CT calcium suppression was perceived as beneficial for percutaneous cryoablation of bone tumors. Cases include cryoablation of a lytic sacral/iliac bone metastasis and cryoablation of recurrent pigmented villonodular synovitis (PVNS) at the posterior aspect of the right knee. Calcium suppression images have a potential role in the visualization of bone lesions for treatment planning and the visualization of ice ball growth for treatment monitoring.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
