^(99m)Tc—MDP骨显像对口腔颌面部肿瘤诊断的评价

(99m)~Tc-MDP Bone Imaging in Evaluation of Neoplasm of Oral and Maxillofacial Regions

本文对22例口腔颌面部肿瘤患者行^(99m)Tc—MDP骨显像检查,将骨显像结果与X线结果进行比较,结果发现:恶性肿瘤骨三相均有核素浓聚,骨病变范围较X线范围大;良性肿瘤,仅延迟相有核素浓聚。对其临床应用价值及良、恶性肿瘤的鉴别诊断进行了讨论。

22 cases with neoplasm of oral and maxillofacial regions were examined by 99mTc-MDP bone imaging, and bone imaging compared with those of X-ray. The results revealed; in malignant group, radionuclide uptake of the area of lesion increased in all three phases, and the lesion range of bone imaging was larger than the one of X-ray, but in the benign group, radionuclide uptake increased only in deley phase. The evaluation of clinical application and differential diagnosis of benign and malignant neoplasm were discussed.
