Methods 24 patients known to suspect of having pulmonary embolism underwent MCTPA with 20 ml contrast medium. Scanning delay time was adjusted by using a test bolos. Contrast medium injection rate was 5.5 ml/s. The time of imaging data acquisition was 2-3 s. In addition 24 patients undergoing MSCTPA with 50 ml contrast medium were included in control group. Imaging quality was evaluated by five degree with blind method.

应用多层螺旋CT对24名疑似肺栓塞的病人行CTPA检查，对比剂总量为20 ml(300 mgI/ml)，以单层动态增强扫描所测时间－密度曲线的峰值时间为扫描延迟时间，对比剂注射速率5.5 ml/s，数据采集时间2~3 s；另随机选择24例常规对比剂剂量(50 ml) CTPA检查影像作为对照组，影像质量按5级行盲法评价。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
