Bone lesions in Ewing's sarcoma (ES/PNET) have been traditionally diagnosed with bone Scan. PET-scan is emerging as a promising investigative modality for detection of metastatic lesions. In this prospective study, we compare the utility of both to detect the metastatic sites. One hundred and seventy five histologically proven cases of ESPNET from 2004-2009 were prospectively staged with bone scan and PET-scan with Breath- hold CT scan- thorax. The diagnostic value of PET-scan to pick up metastatic lesions was compared with bone scan.Background
