目的 通过比较与分析MRI与CT用 于诊断胰腺实性假乳头状瘤的价值，从而 为临床胰腺实性假乳头状瘤的诊断提供重 要参考价值，提高疾病检出率，改善患者 预后。方法 选取本院14例胰腺实性假乳 头状瘤患者采用MRI与CT检查，并与临床 病理检查进行比较。结果 与手术病理检 查结果比较，其中MRI检查4例均与手术病 理结果一致，诊断正确率为100.0%；CT检 查10均与手术病理结果一致，诊断正确 率为100.0%。二者检查正确率比较，无 统计学意义，P>0.05。MRI临床检查诊断 时间平均为(32.5±6.2)min明显长于CT对 照组(17.6±3.4)min，具有统计学意义， P<0.05。结论 相比MRI检查来说，采用CT 检查胰腺实性假乳头状瘤与其诊断正确率 相当，并因CT检查所需时间较短，从而提 高了临床诊断效率，为患者及时治疗和尽 早选择治疗方案提供了一定时间。

Objective Through comparison and analysis of application values of MRI and CT to diagnose solid pseudopapillary tumor of the pancreas, this thesis aims to provide important reference value for clinical diagnosis of solid pseudopapillary tumor of the pancreas, so as to improve the detectable rate and the prognosis. Methods 14 patients with solid pseudopapillary tumor of the pancreas of our hospital are selected for MRI and CT scan and their scan results are taken for comparison with clinical pathological examinations. Results After comparison with the results of pathological examination for operations, it is found that MRI scan results of 4 patients are completely consistent with pathological examination results and the rate of correct diagnosis is 100.0%; the results of 10 patients' CT scan are completely consistent with the results of pathological examination for operations and the rate of correct diagnosis is 100.0%. The comparison of the correct rates of MRI and CT diagnoses has no statistical significance, P>0.05. The average time of MRI clinical diagnosis is (32.5±6.2)min, which is apparently longer than that of CT control group (17.6±3.4)min; this is of statistical meaning, P<0.05. Conclusion In comparison with MRI diagnosis, the correct rate of using CT to diagnose the solid pseudopapillary tumor of the pancreas is equivalent; besides, the time required for CT diagnosis is relatively shorter, this can enhance the clinical diagnosis efficiency and save certain time for patients' early selection of treatment program and early treatment.
