问题 下述哪一种情况可不拍摄颅脑CT的骨窗
选项 A.蝶鞍 B.脑萎缩 C.颅脑外伤 D.颅骨病变 E.内听道病变
答案 B

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
