A simplified technique for localizing and verifying the correct biopsy site of lesions identified on a bone scan has been utilized. A hand-held gamma counter was used for localization of incision placement, determination of extent of bone to be resected, and verification that appropriate tissue was resected. This technique was used to guide biopsy of bony lesions in five patients and to guide resection of a pubic ramus chondrosarcoma. We conclude that intraoperative use of a gamma counter to guide biopsy of bony lesions minimizes surgery time, increases the confidence of obtaining correct tissue, and makes a frequently frustrating procedure very simple. In addition, the probe may assist with determining adequate margins at definitive resection of tumours which accumulate technetium-99m MDP.
一种用于定位和验证骨扫描中发现的病变正确活检部位的简化技术已被采用。使用手持式γ计数器来定位切口位置、确定要切除的骨范围以及验证是否切除了合适的组织。该技术用于指导5例患者的骨病变活检以及耻骨支软骨肉瘤的切除。我们得出结论，术中使用γ计数器指导骨病变活检可缩短手术时间，增加获取正确组织的信心，并使一个常常令人沮丧的操作变得非常简单。此外，该探头可协助确定在对积聚锝-99m亚甲基二膦酸盐的肿瘤进行根治性切除时的足够切缘。
