众所周知,99mTc-亚锡亚甲基二磷酸(MDP)骨显像在诊断原发性和继发性骨肿瘤方面有很高的阳性率,已成为早期诊断原发性和转移性骨肿瘤重要的检查手段,但由于其特异性较差,对良恶性骨肿瘤的鉴别缺乏有力的佐证,特别对单发病灶易造成误诊。为此,本文对186例99mTc-MDP骨显像呈单发病 It is well-known that 99mTc-MDP bone imaging has a high positive rate in the diagnosis of primary and secondary bone tumors and has become an important tool in the early diagnosis of primary and metastatic bone tumors Check the means, but because of its poor specificity, the lack of strong evidence of the differential diagnosis of benign and malignant tumors, especially for single lesions easily lead to misdiagnosis. To this end, this article on 186 cases of 99mTc-MDP bone imaging was single disease
