[SPECT/CT radiation in treatment of bone metastases of osteosarcoma].

The aim of this study was to demonstrate the diagnostic ca- pabilities to control effects of radiotherapy treatment in patient with osteosarcoma bone metastases by SPECT-CT method. There was conducted SPECT/CT treatment monitoring of the patient with bone metastases of osteosarcoma after external radiotherapy and cyber knife. There were detected changes in the SPECT/CT-pictures of treated bones osteosarcoma metasta- ses. The SPECT/CT has proven as a reliable method of dynam- ic control at radiotherapy. Treatment effect all of these methods was to reduce or to get absent accumulation of bone-tropic radiopharmaceutical labeled with 99mTc-technetium. SPECT/ CT study was a demonstrative method for early determination of pathological metabolism degree in bone metastases of os- teosarcoma. SPECT/CT was an effective method of treatment monitoring of bone metastases after radiotherapy.
