Radiology:胰腺导管内乳头状粘液性肿瘤恶性潜能

2019-12-18 shaosai MedSci原创

背景:胰腺导管内乳头状粘液性肿瘤(IPMNs)临床管理国际指南2017版中更新了一些内容。然而,其诊断价值尚未明确。本研究旨在评估修订版指南预测胰腺IPMN恶性潜能的价值,比较对比增强CT和MRI的诊断价值和设备间一致性。

背景:胰腺导管内乳头状粘液性肿瘤(IPMNs)临床管理国际指南2017版中更新了一些内容。然而,其诊断价值尚未明确。本研究旨在评估修订版指南预测胰腺IPMN恶性潜能的价值,比较对比增强CT和MRI的诊断价值和设备间一致性。

本研究为回顾性研究,由两名放射科医师分析经手术切除证实的胰腺IPMN的增强扫描CT和MRI图像。利用ROC曲线分析CT和MRI的诊断价值。利用加权κ和ICC评价设备间一致性。

结果为,本研究共纳入了86例胰腺IPMN患者。在CT和MRI图像中,恶性IPMN肿增强粘膜结节、主胰管径口节段性变化、淋巴结病变、主胰管管径扩大和囊性病变明显扩大的发生率要明显高于良性IPMN。无论检查类型,增强粘膜结节不小于5mm具有最高的OR值。CT和MRI诊断恶性IPMN的ROC曲线下面积无明显差异,分别为0.83 [95% CI: 0.75, 0.92]) 、 0.86 [95%CI: 0.77, 0.95]),设备间一致性κ = 0.70。

本研究表明,综合修订的CT指标,≥5mm增强粘膜结节与恶性导管内乳头状粘液性肿瘤(IPMN)具有显着相关性,对比增强CT和MRI两种预测恶性IPMN的诊断能力相当。
