目的探究核磁共振成像(MRI)与 电子计算机断层扫描(CT)诊断胰腺囊性病 变的临床应用效果。方法 回顾性分析68 例胰腺囊性病变患者临床资料，以细针 穿刺病理学活检结果为诊断金标准，比 较MRI与CT鉴别诊断胰腺囊性病变的特异 性、灵敏性、准确性及影像特点差异。结 果 MRI鉴别诊断胰腺囊性病变特异性明 显高于CT检查结果(P＜0.05)，但两者灵 敏性及准确性比较均无统计学意义(P＞ 0.05)。MRI对胰腺囊性病变多囊与微囊 变、实性结节、囊液成分检出率均明显高 于CT检查(P＜0.05)；CT对其钙化情况检 出率明显高于MRI检查(P＜0.05)。结论 MRI与CT均可对胰腺囊性病变作出较为准 确的鉴别诊断，其中MRI因特异性较强而 更具优势。

Objective To explore the clinical application effects of magnetic resonance imaging (MRI) and computed tomography (CT) in the diagnosis of pancreatic cystic lesions. Methods The clinical data of 68 cases of patients with pancreatic cystic lesions were retrospectively analyzed. The pathological biopsy results of fine needle aspiration were the gold standards for diagnosis, and the specificity, sensitivity, accuracy and imaging features of MRI and CT were compared in the differential diagnosis of pancreatic cystic lesions. Results The specificity of MRI was significantly higher than that of CT in the differential diagnosis of pancreatic cystic lesions (P<0.05), but there was no significant difference in sensitivity and accuracy between the two methods (P>0.05). The detection rates of polycystic and microcapsular changes, solid nodules and cyst fluid of pancreatic cystic lesions by MRI were significantly higher than those by CT (P<0.05). The detection rate of calcification by CT was significantly higher than that by MRI (P<0.05). Conclusion Both MRI and CT can make relatively accurate differential diagnosis of pancreatic cystic lesions, and MRI has more advantages because of its stronger specificity.
