Text Appearing Before Image:

ppearance of thorax insemi-lateral position. is almost entirely masked by thecentral opacity formed by the spinebehind and the sternum in front,with the exception of the leftlateral aortic bulge, which is notevident in all cases. In the case of aortic aneurismsthere will be seen shadows of varying density and size, projecting to theright or left of the central shadow, limited by rounded, sharply defined, andoften pulsating borders. The direction which the bulge takes may give anindication of the position of the aneurism. A shadow projecting to theright and lying nearer to the front than the back indicates an aneurismof the ascending aorta, whereas a similar bulge to the left, and lying nearerthe back than the front, indicates the presence of an aneurism of thedescending aorta. There are other methods of detecting the position and origin of an aorticaneurism : (1) The tube may be moved from side to side or up and down. (2) The patient may be rotated, and observations made of the change
