title: Westermark's sign in the diagnosis of pulmonary emboli in patients with the adult respiratory distress syndrome.
abstract: Two patients with adult respiratory distress syndrome (ARDS) are described in which the development of localized areas of increased lucency on chest roentgenogram, Westermark's sign, aided in the rapid diagnosis of concurrent pulmonary emboli. Recognition of this radiological sign represents a noninvasive technique for diagnosing this complication.
