本帖为很不错的资源，加分鼓励！由于本版为讨论版，一周后移至资源版。 {MOD}，有没有ppt或者pdf格式分享？ 感谢楼主无私分享
其实核磁也不是万能的，核磁的分辨率有多少大家知道吗？理论上能达到1毫米，临床实践中能达到3-5个毫米的病变，才能显示出来。肛瘘的内口到底有多大，有谁知道？1厘米？1毫米？还是多少？有知道的吗？
这里我告诉大家，肛瘘的内口最小的仅有0.2个毫米，你没看错，是0.2个毫米！核磁能看到吗？我告诉你，不能！有人问了，你是怎么知道的？我们有高清的电子**镜，光学放大10倍以上，就是头发丝细小的病变都能看清楚，而且还是彩色的。核磁能做到吗？有一点，核磁能做切面检查，能查瘘管。其实高清的电子**镜，配合**指诊，一样可以查清瘘管，应该比核磁更准确！
好帖。。好帖。。好帖。。 请问指诊，彩超和MRI都没找出来的肛周脓肿应当怎么办呢
