Interruption of the contrast column during inspiration can lead to non-diagnostic CT pulmonary angiograms. The importance of this artefact will increase with more CT studies being performed for pulmonary embolism on multidetector row CT. We describe here an instance of such an artefact and discuss its aetiology.
吸气时对比剂柱中断可导致CT肺动脉造影诊断不明确。随着在多排螺旋CT上对肺栓塞进行更多的CT检查，这种伪影的重要性将会增加。我们在此描述这样一个伪影的实例并讨论其病因。
