摘要 目的探讨慢性胰腺炎、胰腺癌鉴别诊断中联合应用计算机X射线断层扫描(computed tomography,CT)与磁共振成像(magnetic resonance imaging,MRI)增强扫描的临床意义。方法选取2020年1月—2022年3月在吉水县人民医院接受治疗且由手术病理活检结果确诊的30例慢性胰腺炎患者、33例胰腺癌患者作为研究对象,所有患者均应用CT与MRI增强扫描,记录2种疾病患者的胰腺病变性质占有情况、不同检查方式的诊断准确率、胰腺癌病灶直径的对比噪声比(contrast-noise ratio,CNR)情况。结果胰腺癌患者的胰腺体积增大、胰腺周围组织与大血管侵犯、胰腺周围淋巴结肿大、动脉期强化不明显与胰胆管不规则扩张症状占比较慢性胰腺炎患者高(P<0.05),而慢性胰腺炎患者病变及病变周围囊肿、病变钙化、胰胆管平滑状扩张占比较胰腺炎患者高(P<0.05)。在胰腺癌、慢性胰腺炎患者诊断中,与单一CT检查、MRI检查对比,CT联合MRI检查的诊断准确率明显更高(P<0.05);胰体癌患者的病灶直径、不同时期(动脉期、静脉期、延迟期)CNR信号明显大于胰头癌患者(P>0.05)。结论CT联合MRI增强扫描在慢性胰腺炎、胰腺癌患者病情诊断中的准确性相对较高。
