Answer

Delayed or inhomogeneous clearance of 133Xenon can be used to detect small-airway parenchymal injury. However, this study adds little to the clinical management and is not known to offer any particular therapeutic advantage. [44]

Likewise, increased clearance of aerosolized technetium-99m–labeled diethylenetriaminepentaacetate (99mTcDTPA) is a sensitive indicator of injury to the alveolar capillary membrane. However, its clinical use is not yet established.
