Table 2.
Differences between pulmonary imaging artifact and pulmonary artery dissection.
| Baseline data | Pulmonary artifact | pulmonary artery dissection |
|---|---|---|
| Incidence rate | high | rare |
| age | mostly children | mostly adults |
| Medical history | Mostly seen in PDA | chronic IPAH |
| Pulmonary pressure | normal or little high | high |
| Dilation of PA | normal or little wide | Yes |
| Echo view | mainly left high parasternal | Mainly aortic short-axis and pulmonary artery long-axis view |
| Location | changing with views | Fixed |
| CDFI | No interruption | Interruption with flow |
PA: pulmonary artery; PDA: patent ductus arteriosus; IPAH: idiopathic pulmonary artery hypertension; CDFI: color Doppler flow imaging
