[Figure7](http://jnm.snmjournals.org/content/46/8/8a/F7) ON THE COVER Assessment of regional alveolar volume and ventilation is crucial to understanding the pathophysiology of lung injury. Measurement of 13N-N2 washout using PET has been shown to be accurate in assessing these parameters during experimental acute lung injury. This method can now systematically be used to investigate how the distribution of lung ventilation can be changed by interventions such as positive end-expiratory pressure, prone positioning, or recruitment maneuvers and how these changes may affect ventilator-induced lung injury.
