To evaluate the effects of using CO(2) as negative contrast agent in decreasing the overlapping on the pancreaticobiliary system from intestinal fluids.
We evaluated the magnetic resonance cholangiopancreatography (MRCP) images in 117 patients divided into two groups (group 1, without taking gas producing crystals to produce CO(2), n = 64; group 2, with CO(2), n = 53) in a 1.5T unit using MRCP sequence. Anatomic locations of intestinal fluids distribution, overlapping with common bile duct (CBD) and pancreatic duct (PD), were evaluated.
In the group with CO(2), the decrease in distribution of intestinal fluids was significant in the gastric antrum (P = 0.001) and duodenal bulb (P < 0.001), but not in the gastric fundus and body and in the second portion of the duodenum (P = 1.000, P = 0.171, and P = 0.584 respectively). In the group with CO(2), the decrease in overlapping with CBD was significant (P < 0.001), but the decrease in overlapping with PD was not (P = 0.106).
MRCP with carbon dioxide as negative contrast agent would decrease intestinal fluids in the gastric antrum and duodenal bulb, thereby decreasing overlapping with the CBD.
评估使用二氧化碳作为阴性对比剂减少肠道液体对胰胆管系统重叠的效果。
我们在1.5T设备上使用磁共振胰胆管造影（MRCP）序列评估了117例患者的MRCP图像，这些患者被分为两组（第1组，未服用产气晶体产生二氧化碳，n = 64；第2组，使用二氧化碳，n = 53）。评估肠道液体分布的解剖位置，以及与胆总管（CBD）和胰管（PD）的重叠情况。
在使用二氧化碳的组中，胃窦（P = 0.001）和十二指肠球部（P < 0.001）的肠道液体分布减少显著，但胃底和胃体以及十二指肠第二部未减少（分别为P = 1.000、P = 0.171和P = 0.584）。在使用二氧化碳的组中，与CBD的重叠减少显著（P < 0.001），但与PD的重叠减少不显著（P = 0.106）。
以二氧化碳作为阴性对比剂的MRCP可减少胃窦和十二指肠球部的肠道液体，从而减少与CBD的重叠。
