Pantopaque was an oil-based positive contrast media used in central nervous system imaging before the use of water-soluble contrast agents. It is no longer used due to side effects, including arachnoiditis. Prior studies have indicated that remnants of pantopaque can be seen in modern radiographic imaging, including CT and MRI. With its use obsolete, these remnants have been increasingly mislabeled from "tumor" to "shot gun pellets". An understanding of this historic modality will usually lead to the correct diagnosis.
碘苯酯是一种油基阳性造影剂，在水溶性造影剂使用之前用于中枢神经系统成像。由于包括蛛网膜炎在内的副作用，它已不再使用。先前的研究表明，在现代放射成像（包括CT和MRI）中可以看到碘苯酯的残留。随着其不再使用，这些残留越来越多地被错误地标记为“肿瘤”而非“霰弹丸”。了解这种历史上的检查方法通常会得出正确的诊断。
