MRI和CT对急性阑尾炎各征象诊断的比较研究

Contrast Analysis of MRI and CT in the Diagnosis of Acute Appendicitis Various Signs

目的讨论CT和MRI在诊断急性阑尾炎各征象的优势和不足。方法对110例病理证实阑尾炎病人进行研究。其中69例患者使用GE公司Lightspeed Plus16层多排螺旋CT完成层厚1.25mm薄层扫描并进行重建观察;另外41例患者采用SsH/T2W-DR IVE序列、SsH/T2WI序列、STIR/TSE序列和B-SPIR-TFE序列进行MRI扫描。本研究分别对阑尾炎的各个征象进行比较。结果在阑尾炎的各征象中,阑尾壁厚度、粪石及周围渗出情况CT和MRI检查差异有统计学意义,而阑尾直径、阑尾积气、及结构清晰情况两者差异无统计学意义。结论 CT和MRI对急性阑尾炎各项征象的诊断中各有优势。

Objective Evaluation the advantages and disadvantages of the diagnosis of ap- pendicitis by CT and MRI. Methods The prospective study included 110 patients which been confirmed appendicitis by pathologically. 69 cases of CT patients used GE Lightspeed Plus 16 multi-slice spiral CT to complete 1.25mm thick TLC scanning and reconstruction： 41 cases of MRI patients used MRI SsH / T2W-DR IVE sequence, SsH/T2W I sequence, STIR / TSE sequence and B-SPIR-TFE sequence scanning. Various signs of appendicitis were compared respectively. Results According to the comparison between CT and MR1 findings of the appendicitis ,appendix on the appendiceal wall thickness, appendiceal fecalith, effusion around the appendix, the difference was not statistically significant. While the appendiceal diameter,pneumatosis, and the organization structure, the difference was not statistically significant. Conclusion CT and MRI have their own advantages in the diagnosis of various signs of the acute appendicitis.
