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.
