摘要
目的 旨在胰腺肿瘤性病变的诊断过程中对比分析多层螺旋CT与磁共振成像技术各自不同的应用价值，方法 在2020年9月至2023年1月期间在我院对120例经手术病理证实为胰腺肿瘤性病变的患者进行了影像学研究，其中，60例患者接受了多层螺旋计算机断层扫描（MSCT）检查，另外60例则接受了磁共振成像（MRI）检查，以手术切除后所做病理检查得出的结果作为衡量标准，对两种医学检查手段在辨识胰腺恶性病灶方面的精确性、反应灵敏度以及区分特异性进行对比分析。结果 MSCT 和 MRI 对胰腺肿瘤性病变的诊断准确率分别为 86.7%（52/60）和 90.0%（54/60），两者之间的差异在统计学上并无显著性（P＞0.05）；MSCT 和 MRI 对胰腺肿瘤性病变的灵敏度分别为 75.0%（45/60）和 83.3%（50/60），两者之间的差异在统计学上并无显著性（P＞0.05）；MSCT 和 MRI 对胰腺肿瘤性病变的特异度分别为 70.0%（7/10）和 81.8%（9/11），两者之间的差异在统计学上并无显著性（P＞0.05）。结论 MSCT 和 MRI 对胰腺肿瘤性病变的诊断价值相当，两者各有优势，可互为补充。但在某些情况下，MRI 可能更具优势，如对于小胰腺癌、胰腺囊腺瘤等的诊断。

Abstract
Objective To compare the value of multi-slice spiral CT (MSCT) and magnetic resonance imaging (MRI) in the diagnosis of pancreatic neoplastic lesions. Methods The imaging data of 100 patients with pancreatic neoplastic lesions confirmed by surgery and pathology in our hospital from January 2019 to December 2022 were retrospectively analyzed. Among them, 50 cases received MSCT examination and 50 cases received MRI examination. The accuracy, sensitivity and specificity of the two methods in the diagnosis of pancreatic neoplastic lesions were compared with the surgical pathological results as the gold standard. Results The diagnostic accuracy of MSCT and MRI for pancreatic neoplastic lesions was 86.7%(52/60) and 90.0%(54/60), respectively, with no statistical significance (P > 0.05). The sensitivity of MSCT and MRI for pancreatic neoplastic lesions was 75.0% (45/60) and 83.3% (50/60), respectively, with no statistical significance (P > 0.05). The specificity of MSCT and MRI for pancreatic neoplastic lesions was 80.0% (8/10) and 81.8% (9/11), respectively, with no statistical significance (P > 0.05). Conclusion MSCT and MRI are equally valuable in the diagnosis of pancreatic neoplastic lesions. Both have their own advantages and can complement each other. However, in some cases, MRI may be more advantageous, such as for the diagnosis of small pancreatic cancer, pancreatic cystadenoma, etc.
