MSCT对主胰管型胰腺导管内乳头状黏液瘤良恶性鉴别的进展

Distinguishing benign from malignant main duct intraductal papillary mucinous neoplasms of the pancreas by multislice helical computed tomography

主胰管型胰腺导管内乳头状黏液瘤(main duct intraductal papillary mucinous neoplasms,MD-IPMNs)是一种位于扩张的主胰管内、伴大量黏液分泌的肿瘤,该病恶变程度高且缺乏临床特异性.多层螺旋CT(multisliecs helical computed tomography,MSCT)具有层厚薄、分辨率高、多期动态扫描及多种后处理技术等优势,可以对该病进行较为准确的诊断和良恶性鉴别,从而指导临床制定治疗方案、评估患者预后.本文就国内外近年来关于MSCT对MD-IPMNs的诊断及良恶性鉴别的研究现状作一综述.

Main duct intraductal papillary mucinous neoplasms （MD-IPMNs） of the pancreas are located in the dilated main pancreatic duct and associated with mucin overproduction. They may have a high degree of malignancy and lack specific clinical manifestations. With advantages of thin slice thickness, high resolution, multi-phase dynamic scan and multiple post-processing techniques, multislice helical computed tomography （MSCT） can accurately diagnose and differentiate malignant from benign MD-IPMNs. This paper will review the current advances in differentiating malignant from benign MD- IPMNs by MSCT.
