The internal human morphology can be displayed in many formats. The task facing the radiologist is to interpret this information and make an accurate diagnosis. Errors can occur in this process and the interpretive problem facing the radiologist is well illustrated in mass surveys of lung cancer (Guiss and Kuenstler, 1960) and tuberculosis (Yerushalmy, 1969). In these studies experienced radiologists were asked to report on large numbers of chest radiographs and in so doing failed to report some 20–30 per cent of films which contained demonstrable evidence of disease. It is not known whether this error rate is in any way typical or due to the particular constraints of these studies. It is important to understand why such errors do arise so that steps can be taken to minimise them.
