MRCP was performed for 17 patients with MPT (main duct type; 7 and branch duct type; 10) using HASTE and single shot RARE with a body phased array coil on a 1.5 T unit. The findings of MRCP were compared with those of endoscopic retrograde cholangiopancreatography (ERCP). In all cases, MRCP completely disclosed all dilated ducts and cysts, some of which were not seen by ERCP due to mucinous accumulation. In five of seven patients with main duct type, an excrescent nodle was more clearly visualized by ERCP than by MRCP. Mucinous accumulation was not confirmed by MRCP in all cases except one case, in which the dilated branch duct was revealed as lower intensity compared with the main duct using single shot RARE. Therefore MRCP and ERCP are complementary methods in diagnosis for the mucin producing pancreatic tumor.
对17例黏液性胰腺肿瘤患者（主胰管型7例，分支胰管型10例）采用快速自旋回波（HASTE）序列和单次激发快速自旋回波（single shot RARE）序列，使用体部相控阵线圈在1.5T磁共振成像设备上进行磁共振胰胆管造影（MRCP）检查。将MRCP的检查结果与内镜逆行胰胆管造影（ERCP）的结果进行比较。在所有病例中，MRCP均能完整显示所有扩张的导管和囊肿，其中一些因黏液积聚ERCP未能发现。在7例主胰管型患者中的5例中，ERCP比MRCP更清晰地显示出异常结节。除1例病例外，MRCP在所有病例中均未证实有黏液积聚，在该病例中，使用单次激发快速自旋回波序列时，扩张的分支胰管相对于主胰管显示为低信号强度。因此，MRCP和ERCP在诊断黏液性胰腺肿瘤方面是互补的方法。
