摘　　要：目的：探讨螺旋ＣＴ对食管癌临床应用价值，并与传统ＣＴ相比较。材料与方法：螺旋ＣＴ组食管癌１２例均行多平面重建，并与３５例行传统ＣＴ扫描者进行轴位图像比较；７例螺旋ＣＴ扫描后在工作站经软件处理行食管仿真内窥镜成像。结果：（１）１２例食管癌螺旋ＣＴ扫描与传统ＣＴ扫描轴位图像所见几乎完全一致，可以观察病变形态，侵及范围，了解有无转移情况等，与手术病理相符。而螺旋ＣＴ多平面重建可以沿食管走行进行曲面多平面重建，以最佳角度，不同方位来观察食管肿瘤位置、周围受浸范围。（２）７例食管癌ＣＴ仿真内窥镜可从头端或足端入路观察食管壁及肿瘤在腔内的改变等，与纤维食管胃镜所见一致。结论：螺旋ＣＴ与传统ＣＴ相比，除了可以轴位观察食管病变情况，还可以利用多平面重建及ＣＴ仿真内窥镜来观察食管病变特征，为诊断提供更多，更全面的信息。ＣＴ信真内窥镜也是纤维食管胃镜的重要补充方法。Objective: To evaluate the spiral CT in clinical application for esophageal neoplasm by comparing it with conventiona l CT. Materials and Methods:Spiral CT scanning and image process ing with MPR was performed in 12 cases. A comparison was made between the images from spiral CT and the images from conventional CT (35 cases). Virtual endoscop y was conducted on 7 cases scanned by spiral CT, and the findings were compared with fiberoptic esophagogastroscopy. Results:(1) On axial images with spiral CT, all lesions of 12 patients showed almost the same pictures as seen with conventional CT. MPR i n 12 cases could well display esophageal structure through different angle and d irection. (2) CT virtual endoscopy could let one view esophageal lumen and lesio n either cephalocaudad or caudocephalad, and the findings were quite consistent with that seen with fiberoptic esophagogastroscopy. Conclusion: Compared with conventional CT, spiral CT can n ot only display esophageal lesions axially, but also can precisely demonstrate t he morphological features of the lesions with MPR and virtual endoscopy techniqu e, providing clinicians with more useful information.
