This study was designed to determine the effects of intravenous fentanyl on magnetic resonance cholangiopancreatography image quality in the treatment of pancreaticobiliary disorders.
Forty consecutive patients referred for the evaluation of pancreaticobiliary disorders underwent magnetic resonance cholangiopancreatography in the coronal and oblique-coronal planes before and after fentanyl injection (every 2 up to 9 min). The images were analyzed qualitatively and quantitatively. Diameter and signal intensity were measured at the widest point and distal to the common bile duct and main pancreatic duct.
The mean common bile duct diameters at the widest and distal points and mean pancreatic duct diameter were measured 7.53, 4.72, and 2.14 and 8.33, 5.35, and 2.57 before and after fentanyl injection, respectively. Mean signal intensity at the widest and distal point of the common bile duct and mean pancreatic duct signal intensity measured 278, 199, and 113 and 296, 218, and 121 before and after fentanyl injection, respectively. Minor improvements in image quality were detected qualitatively.
Fentanyl injection improves images qualitatively and quantitatively. In agreement with previous studies, our results confirm the beneficial effects of fentanyl as a simple adjunct to traditional magnetic resonance cholangiopancreatography.
本研究旨在确定静脉注射芬太尼对胰胆管疾病治疗中磁共振胰胆管造影图像质量的影响。
40例连续转诊来评估胰胆管疾病的患者在注射芬太尼前及注射后（每2至9分钟一次）在冠状面和斜冠状面接受磁共振胰胆管造影检查。对图像进行定性和定量分析。在胆总管和主胰管最宽处及远端测量直径和信号强度。
注射芬太尼前后，胆总管最宽处和远端的平均直径以及主胰管平均直径分别为7.53、4.72和2.14以及8.33、5.35和2.57。胆总管最宽处和远端的平均信号强度以及主胰管信号强度在注射芬太尼前后分别为278、199和113以及296、218和121。定性检测到图像质量有轻微改善。
注射芬太尼在定性和定量方面均改善了图像。与先前研究一致，我们的结果证实了芬太尼作为传统磁共振胰胆管造影简单辅助手段的有益效果。
