Normal ct rv lv ratio plus readily obtained five clinical predictors were adequate to exclude rv strain or pe related short term mortality.
Neither rv lv diameter ratio nor embolic burden was associated with increased risk of death.

The rv lv ratio had poor specificity in detecting ph at rhc however suggesting that the rv lv ratio at ct imaging cannot be relied on to exclude ph.

The rv lv ratio had poor specificity in detecting ph at rhc however suggesting that the rv lv ratio at ct imaging cannot be relied on to exclude ph.
Quantitative cardiac ct measurements obtained on axial ct images namely the rv short axis the lv short axis and particularly the rv lv short axes ratio have shown a significant positive rv short axis rv lv diameter ratio or negative lv short axis correlation with the severity of pe 37 or with fatal outcome 38 39 fig 2.
