右前斜位

结论：右前斜位升主动脉造影是诊断这一罕见先天性心脏病的最佳心血管造影体位。

Conclusion : The RAO view of ascending aortogram was the best view for angiocardiographic diagnosis of this rare congenital heart disease .

右前斜位20°～40°、正位适合观察右冠状动脉的主要分支；

The branches of RCA can be observed properly from right anterior oblique view with an angle of 20 °~ 40 ° or from posterior anterior view .

子宫动脉开口显示在左、右前斜位25°～30°头侧倾斜15°对子宫动脉显露最为理想。

The ideal demonstration of the uterine artery was on the projection of 25 ~ 30 degree toward left or right anterior obliquity with 15 degree at which the tube tilts the head .

目的：报告食道钡剂造影直立右前或左后斜位X相中食道上段钡影后方紧贴有一软组织密度带状影新征象，并探讨X线成像机理。

Objective : To report a new X-sign on esophagram which is a strip shadow of soft tissue density in the upper part of esophagus behind the barium and study its anatomical basis .

本组左冠状动脉常规位置投照总次数为304次，右冠状动脉为172次，右前斜位同左前斜位投照次数接近，正位较侧位略多。

In this series , total conventional projection in LCA was 304 , whereas the RCA was 172 . The frequency of RAO projection was almost the same as LAO , the number of AP projection was slightly higher than that of lateral .

在造影时可根据需要行右心房、下腔静脉双向同时造影，亦可补充右前斜位投照，以便使梗阻形态显示更清楚。

The radiocardiography of right atria and inferior vena cava ( IVC ) may be done at the same time if needed so that the shape of obstruction of IVC can be demonstrated clear .
