120 chest films with and without nodules were digitized with matrices of 1024 and 2048 pixel and analyzed on a 1024-CRT by 5 radiologists. A significant deterioration in diagnostic performance was observed for the digitized images compared with the original films. Detection rate was influenced by contrast of the lesion against the surroundings and unaffected by lesion size. A strong relationship was noted between detection rate, reporting time and the location of the lesion.
