We evaluate the usefulness of MRCP using respiratory triggered HASTE technique in 68 patients. Eleven subsequent slices were obtained for MRCP. To determine the optimal trigger rate, MRCP with various trigger rates were compared in 25 patients. Respiratory triggered MRCP and breath hold MRCP were compared in 68 patients. Respiratory triggered MRCP was also performed in 3 infants. The optimal trigger rate was 10%. In 17 patients who could not stop their breath for 10 seconds, respiratory triggered MRCP were better than breath hold MRCP in 14 (82%) for the source images and in 17 (100%) for the MIP images. Respiratory triggered MRCP could depict cystic duct and main pancreatic duct even in 14 month infant. MRCP with high spatial resolution could be obtained with respiratory triggered HASTE technique in critically ill, or non-cooperative patients.
我们评估了采用呼吸触发HASTE技术的磁共振胰胆管造影（MRCP）在68例患者中的应用价值。获取了11层后续层面用于MRCP检查。为确定最佳触发率，对25例患者采用不同触发率的MRCP进行了比较。对68例患者的呼吸触发MRCP和屏气MRCP进行了比较。还对3例婴儿进行了呼吸触发MRCP检查。最佳触发率为10%。在17例无法屏气10秒的患者中，对于源图像，呼吸触发MRCP在14例（82%）患者中优于屏气MRCP，对于最大密度投影（MIP）图像，在17例（100%）患者中优于屏气MRCP。即使在14个月大的婴儿中，呼吸触发MRCP也能显示胆囊管和主胰管。采用呼吸触发HASTE技术，在危重症或不合作患者中可获得具有高空间分辨率的MRCP。
