Abstract：Objective: To study the value of MSCT in the diagnosis of small intestinal calculi. Methods: The clinical features and CT findings of 5 cases of small stones confirmed by surgery pathology were retrospectively analyzed and summarized. Results: In the 5 cases, 2 cases of calculus obstruction occurred in jejunum, which are caused by gallbladder stones; 3 cases of calculus incarcerated in the ileum, among which two cases are caused by gastric stone down, one case of duodenal diverticulum stones down inside. They are characterized by oval nodes within the lumen, density of high and low range, the boundary clear, no reinforcement, visible lumen inside the oval filling defect, visible “rim”, “tap” sign, follow-up inspections, visible “walk” sign. Conclusion: Small stone image performance has a certain characteristic. Compared with the conventional abdominal plain film, ultrasound and barium meal examination, MSCT has obvious diagnostic advantage. Through the image post-processing technology, characteristics of stones in the intestine and the surrounding anatomic relationship can be showed clearly. MSCT may be a useful tool in the qualitative, positioning diagnosis of lesions.
