| 目的 探讨MSCT后处理技术在胰腺导管内乳头状黏液瘤(IPMN)中的诊断价值.方法 对18例经手术病理或超声内镜引导下细针穿刺证实的IPMN患者的临床、病理及MSCT检查资料进行回顾性分析,对MSCT双期增强扫描的原始数据均行MPR、MinIP及CPR,观察病变本身及其与胰管、周围结构的关系.结果 18例IPMN患者中,病变与扩张胰管相通18例(18/18,100%),胰管扩张 >1.0 cm 7例(7/18,38.89%),囊性病变17例(17/18,94.44%),囊实性病变1例(1/18,5.56%).主胰管型6例(6/18,33.33%)、分支胰管型9例(9/18,50.00%)、混合型3例(3/18,16.67%).MPR图像能清晰显示IPMN病变的大小、边界、有无强化的壁结节,也可较好显示病变与扩张胰管间的关系以及病变与周围结构之间的关系;MinIP图像在显示扩张胰管的全貌及病变与扩张胰管间关系等方面优于MPR图像及CPR图像;CPR图像有助于显示主胰管扩张的全貌.结论 利用MSCT多种后处理技术可整体显示病变、扩张胰管以及周围结构,在IPMN诊断方面具有重要价值. |

| Objective To explore the value of MSCT post-processing techniques in diagnosis of intraductal papillary mucinous neoplasm (IPMN). Methods The clinical, pathological and MSCT examination data of 18 cases of IPMN confirmed by operation or endoscopic ultrasound guided fine-needle aspiration (EUS-FNA) were retrospectively analyzed. The original data of MSCT were processed with MPR, MinIP and CPR, and the lesions, and its relationship with the pancreatic duct and surrounding structures were assessed. Results For 18 cases, lesions communicated with dilated pancreatic duct in 18 cases (18/18, 100%), pancreatic duct dilatation >1.0 cm were in 7 cases (7/18, 38.89%), cystic lesions were in 17 cases (17/18, 94.44%), cystic solid lesion was in 1 case (1/18, 5.56%). Six cases (6/18, 33.33%) were the main duct type IPMN; 9 cases (9/18, 50.00%) were the branch duct type; 3 cases (3/18, 16.67%) were mixed type. MPR images clearly showed the size and boundary of cystic lesions, whether there were enhanced wall nodules, which also showed the relationship of lesions with dilated pancreatic duct and surrounding structures. MinIP images were superior to MPR images and CPR images in showing the dilated pancreatic duct, and the relationship between the lesions and dilated pancreatic duct. CPR images were helpful for displaying the whole course of main pancreatic duct dilatation. Conclusion With MSCT post-processing techniques, the reconstructive images can show the lesions, dilated pancreatic duct and the surrounding structures integrally that has important value in diagnosis of IPMN. |
