[单项选择]在造影期间进行两次曝光,一次是在对比剂到达兴趣区之前,一次是在对比剂到达兴趣区并出现最大浓度时。如果病人在曝光过程中保持体位不移动,则两图像之间的唯一差别是含有对比剂的血管,它们两者的差值信号就是DSA的信号。随着血管内碘浓度(PI)与血管直径(d)乘积的增加,DSA差值信号也增加。故DSA的信号由对比剂的投射浓度(PI)和血管直径(d)所决定。在DSA检查过程中,患者本身自主和不自主的移动、心脏搏动、吞咽、呼吸或胃肠蠕动等,可形成运动性伪影。为防止运动伪影,下列做法不正确的是()

[单项选择]I’ve been going home for lunch ever since I started school. I never liked eating in the cafeteria(自助食堂) although in tile seventh grade, because all the other boys were doing it and thought it was cool. I washed dishes in the junior high school lunchroom once in a while in exchange for a free lunch. But I like going back to my own house at once.
Mom is always there; she had soup ready in the breakfast room by the time that Ann and Jim and I get home. Ann and Jim have never gone in for the cafeteria, either. Our house in only about a ten-minute walk from the school building, so we can make it back in plenty of time.
There’s something about eating in the cafeteria--and not leaving the high school from morning until afternoon -- that feels a little like being in prison. By the end of the morning, I’ve got to get out of the building. And Mom never seems to mind fixing lunch for us; she never suggests that we eat in the cafeteria.

[单项选择] Some people would say that the Englishman’’s home is no longer his castle, that it has become his workshop. This is partly because the average Englishman is keen on working with his own hands and partly because he feels, for one reason or another, that he must do for himself many household for which, some years ago, he would have hired professional help. The main reason for this is a financial one. The high cost of labour has meant that builders’’ and decorators’’ cost have reach a level which makes them prohibitive for houseproud English-people of modest means. So, if they wish to keep their houses looking bright and smart, they have to tackle some of the repairs and decorating themselves. As a result, there has grown up in the post-war years what is sometimes referred to as the " do-it-yourself movement".
