探讨多层螺旋CT联合磁共振成像（MRI）在腹壁疝患者中的诊断效果及临床治疗指导价值。

选择2018年1月至2019年11月，文昌市人民医院腹壁疝患者80例作为对象，所有患者均经手术检查确诊，并采用手术治疗；术前所有患者均拟行多层螺旋CT及MRI检查，并将多层螺旋CT及MRI结果与手术结果进行比较；绘制受试者工作特征（ROC）曲线，分析多层螺旋CT、MRI在腹壁疝患者中的诊断效能（敏感性、特异性）及临床治疗指导价值。

CT检查最终确诊67例，临床诊断符合率为83.75%（P<0.05）；MRI检查确诊76例，临床诊断符合率为95.00%（P>0.05）；多层螺旋CT确诊患者疝环直径在2～13 cm，脐疝较小，内容物多为大网膜、小肠；外伤性腹壁疝、切口疝疝环较大，内容物为大网膜、小肠、子宫或膀胱；造口疝内容物多为大网膜、肠袢等；MRI确诊患者疝环直径在1.5～8.5 cm，疝入缺损三角区内容物多为脂肪或合并系膜，影像学上为脂肪及索条影，且疝出内容物大小与疝环不成比例；ROC曲线结果表明：MRI联合多层螺旋CT在腹壁疝患者中的诊断敏感性、特异性均高于单一MRI、CT（P<0.05）。

多层螺旋CT联合MRI用于腹壁疝患者中能获得较高的诊断敏感性、特异性，能为临床治疗提供影像学指导，值得推广应用。

To investigate the diagnostic effect of multi-slice spiral CT combined with MRI in patients with abdominal wall hernia and the value of clinical treatment guidance.

80 patients with abdominal wall hernia from January 2018 to November 2019 were selected as the objects. All patients were confirmed by operation (gold standard) and treated by operation; all patients planned to have multi-slice spiral CT and MRI examination before operation, and the results of multi-slice spiral CT and MRI were compared with the gold standard; ROC curve was drawn to analyze the diagnostic efficacy of multi-slice spiral CT and MRI in patients with abdominal wall hernia (sensitivity, specificity) and clinical treatment guidance value.

67 cases were finally diagnosed by CT, and the coincidence rate of clinical diagnosis was 83.75% (P<0.05); 76 cases were confirmed by MRI, and the coincidence rate of clinical diagnosis was 95% (P>0.05). The diameter of hernia defect was 2 to 13 cm, the size of umbilical hernia and inguinal hernia was smaller, and the contents were mostly greater omentum and small intestine; the diameter of traumatic abdominal wall hernia and incisional hernia were larger, and the contents were greater omentum, small intestine, uterus, or bladder; the contents of stomal hernia were greater omentum and intestinal loop. The diameter of hernial defect in MRI was 1.5 to 8.5 cm, and the contents of the herniated triangle were mostly fat or fat with mesentery. The imaging findings were fat and cord shadow, and the size of the herniated contents was not proportional to the hernia ring. The results of ROC curve showed that MRI combined with MSCT was sensitive and specific in the diagnosis of abdominal wall hernia, and it was superior to single MRI and CT (P<0.05).

MSCT combined with MRI in patients with abdominal wall hernia can obtain high diagnostic sensitivity and specificity, can provide imaging guidance for clinical treatment, and it is worth popularizing.
