问题 常用于慢流静脉及静脉窦成像的技术是
选项 A.3D-TOF-MRA B.2D-CK-MRA C.2D-PC-MRA D.3D-PC-MRA E.3D-CE-MRA
答案 C
解析 :2D-PC-MRA常用于慢流静脉及静脉窦成像,由于2D-PC-MRA能够准确反映流动自旋的流速和方向,结合ECG同步技术,常用于流体的流量分析。3D-PC-MRA的流动背景抑制较好,但其采集时间较TOF_MRA约长一倍。

错误啦!

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.
