问题 A.强回声 B.高回声 C.等回声 D.低回声 E.无回声 瘢痕多呈
选项
答案 B
解析 :此题为记忆题,病理组织中,结石、钙化回声最强;纤维化、血管瘤、血管平滑肌脂肪瘤次之,典型的淋巴瘤回声最低,甚至接近无回声血液常是无回声的,但是新鲜的出血和新鲜血栓常呈低回声,而陈旧血栓由于凝血块中有大量纤维蛋白或机化、钙化,使回声增强

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.
