Abstract
The effect of diaphragmatic attenuation on 231Ti images of the heart was studied by intermittent recording with patients in inspiration and expiration. These studies suggest that the commonly observed posteroinferior defects in the left lateral projection can be explained by this mechanism. Possible effects on the anterior view are also suggested.
摘要
通过让患者在吸气和呼气时进行间歇性记录，研究了膈肌衰减对心脏231Ti图像的影响。这些研究表明，在左侧位投照中常见的后下壁缺损可由此机制解释。还提出了对前位视图可能产生的影响。
