Locetamic acid (Cholebrine) and ipodate sodium (Oragrafin) were compared in a double blind study of 503 patients. The radiographs were evaluated for contrast density, visualization of common duct, gallstones, residual in the intestinal tract, and side effects. Cholebrine demonstrated better opacification, fewer repeat examinations, slightly greater common duct opacification, and more frequent visualization of gallstones. Oragrafin had less residue. Side effects were minimal with both contrast agents.
在一项针对503名患者的双盲研究中，对洛塞他酸（胆影酸）和碘番酸钠（碘奥酮）进行了比较。对X光片进行了对比度密度、胆总管显影、胆结石、肠道残留以及副作用等方面的评估。胆影酸显示出更好的造影效果、更少的重复检查、胆总管显影略好以及胆结石显影更频繁。碘奥酮的残留较少。两种造影剂的副作用都很小。
