Pulmonary Arterial Blood Flow Imaging

Pulmonary arterial blood flow imaging was obtained by pulmonary artery angiography (AlluraXper FD20 Philips). 5–7 ml of contrast was injected for the pulmonary angiography with hand injection with a syringe. The pulmonary circulation time was measured as previously described, by calculating the time taken for the contrast medium to reach from the initiation site of the pulmonary artery trunk to the left atrium through the pulmonary artery trunk and branches, pulmonary capillary, and pulmonary vein. The pulmonary circulation time was calculated for all of the survived rabbits at 120 min after the moment of successfully modeling, which was designed as the study end [6 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
