摘要
目的:探讨99mTc-MIBI亲肿瘤显像在头颈部肿瘤定性诊断中的应用价值。方法:91例临床初诊为头颈部肿瘤的患者和20例正常志愿者行早期和延迟99mTc-MIBI头颈部断层显像。结果:99mTc-MIBI早期/延迟显像诊断头颈部恶性肿瘤的总体敏感度、特异度、准确度及阳性预测值分别为78.7%/72.3%、72.1%/88.4%、75.6%/80.0%和75.5%/87.2%;鼻咽癌、非霍奇金淋巴瘤显像效果优于上颌窦癌9。9mTc-MIBI显像对于鼻咽癌复发/残留以及鼻腔非霍奇金淋巴瘤定性诊断价值明显优于CT和MRI。结论:99mTc-MIBI亲肿瘤显像在头颈部肿瘤的定性诊断中有较好的应用前景。
Objective：To investigate the value of ^99mTc-MIBI scintigraphy in the diagnosis of head and neck tumor. Methods： 91 patients with malignant and benign head and neck lesions underwent ^99mTc-MIBItomography, 20 volunteers served as control. Results.. The overall sensit ivity, specificit y, accuracy and positive predictive accuracy of early/delay ^99mTc-MIBI scintigraphy in diagnosing head and neck tumor were 78.7%/72. 3%,72. 1%/88.4%,75.6%/80.0% and 75.5%/87.2% respectively. The results in nasopharyngeal cancer and non-Hodgkin＇s lymphoma were much better than that in paranasal sinus cancer. Conclusion：^99mTc-MIBI scintigraphy is a very useful tool in diagnosing the head and neck tumors.
