Randomized Controlled Trial Comparative Study Clinical Trial
A prospective randomized clinical trial comparing two film-screen systems for chest radiography.
To compare conventional and asymmetric film-screen chest radiography systems in a prospective, randomized trial. ⋯ In general, the asymmetric system was superior for assessing mediastinal features and inferior for assessing the lateral subpleural zones in the posteroanterior radiographs. The asymmetric system was superior for assessing retrosternal lung markings and inferior for assessing fissures in the lateral radiographs. The results for the posteroanterior radiographs were consistent with the results of nonblinded studies reported elsewhere.
