多层螺旋CT多平面重建后处理技术应用于阑尾黏液性肿瘤病症诊断中的效果

Multi-Layer Spiral CT Multiplanar Reconstruction Post-Processing Technique Applied to the Diagnosis of Appendiceal Mucinous Neoplasm Disease

目的:研究多层螺旋CT多平面重建后处理技术应用于阑尾黏液性肿瘤病症诊断中的临床价值。方法:采用回顾性分析方法,以2017年1月至2022年1月入院的60例阑尾黏液性肿瘤患者为观察对象,所有患者均接受多层螺旋CT多平面重建检查与腹部CT平扫检查,比较两种检查方式的诊断准确率,并分析多层螺旋CT多平面重建表现。结果:60例阑尾黏液性肿瘤患者经多层螺旋CT多平面重建检查的准确率为98.33%,。60例阑尾黏液性肿瘤患者经腹部CT平扫检查的准确率为85.00%。多层螺旋CT多平面重建检查诊断阑尾黏液性肿瘤的准确率明显高于腹部CT检查,差异有统计学意义(P<0.05)。多层螺旋CT多平面重建表现:25例患者肿瘤病灶呈卵圆形,底部、口部变小,中间膨大;13例患者肿瘤病灶呈茄子状,底部、中部膨大,口部变小;13例患者肿瘤病灶呈花生状,囊性肿块整体膨大,底部、口部较中部膨大更为显著,且呈束腰征;9例患者肿瘤病灶呈不规则长管状。多平面重建之后不仅能够清晰显示肿块外形,还可于3个方位(上下径、左右径、前后径)予以测量,以此测量不同形态肿块的狭窄处及膨大处,进而提高肿块大小测量精准性。结论:多层螺旋CT多平面重建后处理技术应用于阑尾黏液性肿瘤病症的诊断中效果显著,可有效提升诊断准确性,且此技术对显示肿瘤形态学上表现具有一定特征,可为临床治疗方案的制定提供参考依据。

Objective:To study the clinical value of multislice spiral CT multiplane reconstruction in the diagnosis of appendicitis mucinous tumor.Methods:A retrospective analysis was conducted,and 60 patients with mucinous tumor of the appendix admitted from January 2017 to January 2022 were selected as the observation subjects.All patients received multislice spiral CT multiplane reconstruction examination and abdominal CT plain scan examination.The diagnostic accuracy of the two examination methods was compared,and the manifestations of multislice spiral CT multiplane reconstruction were analyzed.Results:The accuracy of multislice spiral CT multiplane reconstruction was 98.33%in 60 patients with mucinous tumor of the appendix.The accuracy of abdominal CT plain scan in 60 patients with appendiceal mucinous tumor was 85.00%.The accuracy of multislice spiral CT in the diagnosis of appendiceal mucinous tumor was significantly higher than that of abdominal CT,and the difference was statistically significant(P<0.05).Multislice spiral CT multi-plane reconstruction showed that the tumor lesions in 25 patients were oval,small at the bottom and mouth,and enlarged in the middle.In 13 patients,the tumor lesions were aubergine-like,enlarged at the bottom and middle,and small at the mouth.In 13 patients,the tumor lesions were peanut-shaped,the cystic mass was overall enlarged,and the expansion at the bottom and mouth was more significant than that in the middle,and the tumor showed bunched waist sign.The tumor lesions of 9 patients were irregular and long tubular.After multi-plane reconstruction,not only the shape of the tumor can be clearly displayed,but also the three directions(upper and lower diameters,left and right diameters,front and rear diameters)can be measured,so as to measure the stenosis and enlargement of different shapes of the tumor,thus improving the accuracy of the measurement of the tumor size.Conclusion:The application of multi-slice spiral CT multi-plane reconstruction post-processing technology in the diagnosis of mucinous tumors of the appendix has significant effects,which can effectively improve the diagnostic accuracy.Moreover,this technology has certain characteristics in the morphologic manifestations of tumors,and can provide reference for the formulation of clinical treatment plan.
