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 search for a noninvasive and effective preoperative qualitative diagnostic method for nasopharyngeal fibrovascular tumors. Methods: Three patients with nasopharyngeal fibroadenoma were examined with 99mTc MIBI. Results: The nasopharyngeal angiofibroma was weakly positive in all the early stages of imaging, and the delayed imaging showed the radioactive defect. There was a significant difference between the positive results of malignant tumors and the negative findings of benign tumors. CONCLUSION: The 99mTc MIBI head and neck tumor-free tumor imaging is noninvasive to patients. The imaging results of the 99mTc MIBI have certain characteristics. It can be used as a noninvasive and effective qualitative diagnostic method for nasopharyngeal hemangiomas.
