Percutaneous needle biopsy was performed in 20 patients who had radiologic abnormalities after irradiation of the skeleton. The biopsies were performed to determine the nature of the bone changes and to differentiate radiation necrosis from metastases or local tumor extension. Eleven patients had tumors, two of which were radiation-induced sarcomas; nine patients did not show evidence of tumor. One patient had osteomyelitis rather than the suspected tumor. The value of percutaneous needle biopsy in the postirradiated skeleton is discussed.
对20例骨骼照射后出现放射学异常的患者进行了经皮穿刺活检。进行活检的目的是确定骨改变的性质，并区分放射性坏死与转移瘤或局部肿瘤扩展。11例患者患有肿瘤，其中2例为放射性诱发的肉瘤；9例患者未显示肿瘤迹象。1例患者患有骨髓炎而非疑似肿瘤。本文讨论了经皮穿刺活检在骨骼照射后的价值。
