16层螺旋CT对上颌窦病变的诊断价值

Evaluation of the accuracy of 16 slices spiral CT in diagnosing maxillary sinus diseases

目的:探讨16层螺旋CT对上颌窦病变的诊断价值。方法:对58例临床诊断为上颌窦病变的患者行16层螺旋CT扫描,然后将扫描数据传入工作站进行后处理成像,并对16层螺旋CT图像结合临床进行分析,所有病例均经手术证实。结果:58例患者中,炎性病变30例;良性肿瘤6例;恶性肿瘤8例;上颌窦骨折14例。16层螺旋CT定位诊断正确率达100%,定性诊断正确率达91.38%。结论:16层螺旋CT能较好地显示上颌窦病变的范围、骨质改变的程度及与周围组织的关系,但定性诊断还需密切结合临床和病理学表现。

PURPOSE： To investigate the diagnostic value of 16 slices spiral CT in maxillary sinus diseases. METHODS： 16 slices spiral CT findings of 58 cases with maxillary sinus diseases confirmed clinically were analyzed, postprocessing of images was performed by using the software package at the workstation. All the cases were proved by surgery. RESULTS： Among 58 cases, there were 30 cases with inflammatory diseases; 6 cases with benign tumors; 8 cases with malignant tumors and 14 cases with fractures. The correct rate of CT diagnosis for location was 100%, and for the nature of the disease was 91.38%. CONCLUSIONS： 16 slices spiral CT was proved to be a good way to show the range of maxillary sinus diseases, the degree of bony change and the relation to surrounding tissues, but determination of the nature of the diseases should be incorporated with clinical and pathological findings.
