鼻咽纤维血管瘤的^(99m)-TcMIBI显像

^(99m)Tc-MIBI imaging of nasopharyngeal angiofibroma

目的 :为鼻咽纤维血管瘤寻找无创而有效的术前定性诊断方法。方法 :采用99mTc MIBI对 3例鼻咽纤维血管瘤患者进行头颈部亲肿瘤显像检查。结果 :3例鼻咽纤维血管瘤的早期显像均呈弱阳性 ,延迟显像均表现为放射性分布缺损 ,与恶性肿瘤的阳性显像结果及良性肿瘤的阴性显像结果有明显区别。结论 :99mTc MIBI头颈部亲肿瘤显像对患者无创 ,其显像结果具有一定的特征 ,可作为鼻咽纤维血管瘤术前无创而有效的定性诊断方法。

Objective:To explore a noninvasive, effective and preoperative method of diagnosis for nasopharyngeal angiofibroma.Method:The craniocervical examination oncotropic by 99m Tc-MIBI imaging was performed in 3 patients with nasopharyngeal angiofibroma.Result:Early 99m Tc-MIBI imaging was weakly positive and late its imaging was radioactively defective in 3 cases of nasopharyngeal angiofibroma. 99m Tc-MIBI imaging of the angiofibroma was significantly different from that of malignant and benign tumors.Conclusion: 99m Tc-MIBI oncotropic imaging is of qualitatively diagnostic value for nasopharyngeal angiofibroma before operation, because 99m Tc-MIBI imaging was of certain features.
