Five thousand acute care/emergency department chest radiographs: comparison of requisitions with radiographic findings.

Five-thousand portable or posterior-anterior-lateral radiographs of acute care emergency department patients were interpreted. They revealed serious disease in 35% of patients with chest symptoms, in 27% of all patients examined, and in 18% of patients with noncardiorespiratory symptoms. The highest incidence of abnormal radiographs (42%-79%) occurred in patients with symptoms of congestive heart failure, dyspnea, hemoptysis, dysrhythmia, and hypertension.

Cooperative study of radiologic aspects of renovascular hypertension. Bilateral renovascular disease.

Abnormal urographic features were present in 60.7% of 250 patients with bilateral diseases. The urogram was relatively insensitive in the minority of patients whose lesions were of approximately equivalent severity bilaterally.
