Value Of ^99mTc-MIBI SPECT And SPECT/CT Fusion Imaging In Diagnosis Of Tumor In The Oral And Maxillofacial Region

[Objective]To study the value of ^99mTc-MIBI SPECT imaging and SPECT/CT fusion imaging in oral and maxillofacial tumor,to provide a reference of preoperative differential diagnosis and treatment.[Methods]The first part:40 patients with maxillofacial masses were enrolled.After intravenous administration of ^99mTc-MIBI,static planar imaging and fusion imaging of head and neck were obtained,their results compared with CT and pathology.The second part:30 patients with maxillofacial tumor were enrolled.After intravenous administration of ^99mTc-MIBI,static planar imaging and fusion imaging of head and neck were obtained.Compared static planar imaging with fusion imaging,to investigated the clinical value of SPECT/CT in parotid gland masses.[Results]1 There was significant difference in ^99mTc-MIBI SPECT static planar imaging to differention diagnosis of benign and malignant maxillofacial tumor.The diagnosis of parotid gland tumor were better than the other areas in maxillofacial tumor.2 The sensitivity,specificity and accuracy of ^99mTc-MIBI SPECT/CT fusion imaging to differention diagnosis of benign and malignant parotid gland tumor;Ratio of SPECT ^99mTc-MIBI T/N of two groups were 1.42±0.62,2.32±0.58,there was signification differention to two groups.[Conclusion]1 SPECT'S sensitivity was higher than CT,it could be looked as a routine method to differention diagnosis of benign and malignant oral and maxillofacial tumor,diagnosis of parotid gland tumor were better than the other areas in oral and maxillofacial tumor,if necessary,SPECT combined with CT may play an important role in diagnosis of the maxillofacial tumor.2 ^99mTc-MIBI SPECT/CT fusion imaging is a very useful tool in diagnosing the parotid gland tumor.
