Table 5 Comparison of average pressure drop and total energy loss in the branch PA in this study with physiological data

From: Non-invasive evaluation of energy loss in the pulmonary arteries using 4D phase contrast MR measurement: a proof of concept

    Pressure drop
Total energy loss
Normal RPA 4D PC MRI −0.09 −2.1
Physiological data −0.12 −3.7
Patient RPA 4D PC MRI −1.3 −96.9
  LPA Physiological data −3.7 −41.9
