摘　　要：目的通过对造釉细胞瘤不同影像学检查的比较,提高对造釉细胞瘤的影像诊断水平。方法选择术前行口腔全景片、多层螺旋CT及MR检查,术后病理证实的造釉细胞瘤31例,从显示病变的位置、形态、内容物的性质、牙根的改变、病灶周围骨质的改变及对下颌管的侵犯等方面对各种影像学检查方法进行评价。结果 31例中,3种检查方法均能清楚显示病灶的位置,口腔全景片中有27例可清楚显示牙根的改变;CT检查中31例均能清楚显示病灶的形态及病灶周围骨质的改变,27例可清楚显示牙根的改变,25例可明确病灶内容物的性质,18例可显示下颌管的侵犯;MR检查中31例均能明确病灶的范围及病灶内容物的性质。结论不同的影像学方法对造釉细胞瘤影像学特征的显示能力不同,联合应用能提高造釉细胞瘤的诊断准确率。Objective To compare different imaging features of ameloblastomas of jaw bone in order to improve the im- aging diagnosis accuracy of ameloblastomas. Methods The preoperative panoramic X-ray, multi-slice spiral CT and MR imaging of 31 patients with patbologically-confirmed ameloblastomas were enrolled in this study. The location, shape and contents of the lesion, the changes of tooth root and adjacent bony structures, and the invasion of canalis mandibulae on the images obtained by different imaging techniques were analyzed. Results The lesion＇ s location could be clearly displayed by X-ray, muhi-slice spiral CT and MRI in all 31 patients. The changes of tooth root could be detected by panoramic X-ray in 27 patients. CT scanning could clearly show the lesion＇ s shape and adjacent bony structures in 27 cases, and could re- veal the lesion＇ s contents in 25 cases. The invasion of canalis mandibulae was detected in 18 cases. MRI could show the lesion＇ s extent and lesion＇ s contents in all 31 cases. Conclusion Different imaging modalities have different abilities in displaying the features of ameloblastomas. The combination use of panoramic X-ray, muhi-slice spiral CT and MRI can im- prove the diagnosis accuracy of ameloblastomas.
