@@@@64排螺旋CT后处理技术对回盲部病变的诊断价值

目的:分析回盲部良恶性病变64排螺旋CT成像特点及其后处理技术的诊断价值。方法:搜集手术病理证实的回盲部病变53例，所有病例均行CT平扫+增强扫描，分析回盲部良恶性病变的成像特点，比较原始轴位图像与后处理图像的诊断效果。结果:原始轴位图像联合MPR/CPR定位定性诊断准确性均高于原始轴位图像，并且差异具有统计学意义（P=0.03；P=0.04）。MPR、CPR能清晰完整地显示回盲部病变的内外结构与邻近器官的关系，提高对回盲部病变的诊断准确性。结论:64排螺旋CT可准确、直观地显示回盲部病变，原始轴位图像结合MPR/CPR图像可以提高对回盲部病变的诊断准确率。 

Diagnostic Value of 64-slice Spiral CT Post-processing on Ileocecal Lesions

Objective: Analyze the imaging characteristics of 64-slice spiral CT in benign and malignant ileocecal lesions and the diagnostic value of post-processing techniques.Methods: 53 cases of ileocecal lesions confirmed by operation and pathology were collected.All cases underwent CT plain scan and enhanced scan.The imaging characteristics of benign and malignant ileocecal lesions were analyzed and the diagnostic effects of original axial image and post-processing image were compared.Results: The accuracy of localization and qualitative diagnosis of original axial images combined with MPR/CPR was higher than that of original axial images, and the difference was statistically significant(P=0.03;P=0.04).MPR and CPR can clearly and completely display the relationship between internal and external structures of ileocecal lesions and adjacent organs, and improve the accuracy of diagnosis of ileocecal lesions.Conclusion: 64-slice spiral CT can display ileocecal lesions accurately and intuitively.The combination of original axial images with MPR/CPR images can improve the diagnostic accuracy of ileocecal lesions.
