The aim of this study was to determine the usefulness of MR cholangiopancreatography (MRCP) of intraductal papillary-mucinous tumors.
Thirteen patients with intraductal papillary-mucinous tumors were examined by breath-hold MRCP using a half-Fourier acquisition single-shot turbo spin echo (HASTE) sequence with a body phased-array coil.
Endoscopic retrograde cholangiopancreatography (ERCP) and MRCP completely imaged the entire main pancreatic duct in 12 and in all 13 patients, respectively. ERCP demonstrated the whole opacification of the cystic lesion in only one patient. MRCP depicted the whole of the cystic lesion in all 11 patients who had cystic lesions. ERCP and MRCP source images depicted a communicating duct between the main pancreatic duct and the cystic lesion in 8 and in all 11 patients, respectively. ERCP depicted papillary projections in the main pancreatic ducts in two patients. MRCP source images depicted papillary projections in the main pancreatic ducts or cystic lesions in five patients.
MRCP may be more useful to reveal the main pancreatic duct, cystic lesion, communicating duct between the main pancreatic duct and cystic lesion, and papillary projections than ERCP in patients with intraductal papillary-mucinous tumors of the pancreas.
本研究旨在确定磁共振胰胆管造影（MRCP）对导管内乳头状黏液性肿瘤的诊断价值。
13例导管内乳头状黏液性肿瘤患者采用体部相控阵线圈，运用半傅里叶采集单次激发快速自旋回波（HASTE）序列进行屏气MRCP检查。
内镜逆行胰胆管造影（ERCP）和MRCP分别使12例和全部13例患者的主胰管完全显影。ERCP仅使1例患者的囊性病变完全显影。MRCP使全部11例有囊性病变的患者的囊性病变完全显影。ERCP和MRCP原始图像分别使8例和全部11例患者的主胰管与囊性病变之间出现交通支显影。ERCP使2例患者的主胰管内出现乳头状突起显影。MRCP原始图像使5例患者的主胰管或囊性病变内出现乳头状突起显影。
对于胰腺导管内乳头状黏液性肿瘤患者，MRCP在显示主胰管、囊性病变、主胰管与囊性病变之间的交通支以及乳头状突起方面可能比ERCP更具优势。
