摘　　要：目的 探讨CT灌注成像在单发骨转移瘤与原发恶性骨肿瘤鉴别诊断中价值.方法 回顾性分析经手术病理证实的14例单发骨转移瘤和15例原发恶性骨肿瘤的CT灌注检查.结果 单发骨转移瘤和原发恶性骨肿瘤在灌注参数方面无明显不同,但在是否伴有高灌注的软组织肿块或低灌注的中央坏死区方面有明显不同：单发骨转移瘤是2例（14.3%）,原发恶性骨肿瘤是13例（86.7%）.结论 CT灌注成像有助于鉴别单发骨转移瘤与原发恶性骨肿瘤,可以详细全面提供医生制定手术计划所需要的骨肿瘤的性质和血供情况的信息.Objective To evalute the value of CT perfusion imaging in differentiating single bone metastases from primary malig nan. bone tumors. Melhods CT perfusion findings in 11 cases with single bone metastases and 15 cases with primary malignant bone tumors proved by operation and pathology were relrospetively analyzed. Results There was no significantly statistical difference in the CT perfusion parameters , but there was significantly statislical difference in whether accompanied with high perfusion soft tissue mass or low perfusion necrotic centre between single bone metastases and primary malignant hone tumors,including single bone me tastasis in 2 cases （1 ：l. 3 %） ,whereas primary malignant bone tumor in 13 cases （86.7 % ）. Conclusion CT perfusion imaging might be helpful in the differential diagnosis of single bone metastases and primary malignanl bone tumors, lnformations about the nature and blood supply of tumors are inlportant in presurgicaI planning and CT perfusion is feasible and safe for what bone tumor surgeons required.
