Criteria for shunt vascularity
Criteria for shunt vascularity
Which of the following is a criteria for shunt vascularity
[A] Right asending pulmonary artery diameter > 17 mm
[B] Right descending pulmonary artery diameter > 15 mm
[C] Right descending pulmonary artery diameter > 17 mm
[D] Left descending pulmonary artery diameter > 15 mm
Criteria for shunt vascularity
Criteria for shunt vascularity include
- (1) Uniformly distributed vascular markings with absence of the normal lower lobe vascular predominance
- (2) Right descending pulmonary artery diameter that exceeds 17 mm
- (3) Pulmonary artery branch that is larger than its accompanying bronchus (best noted in the right parahilar area)
