[Diagnostic reliability and economic profitability of 105 mm photography in digestive radiology].
A strict methodology using data-processing programmes was employed to compare diagnostic reliability and economic profitability of 105 mm photography and conventional radiography during 500 radiological examinations of the digestive tract. Films were evaluated twice on two separate occasions to determine correlation with predicted diagnosis and the amount of film exposed during the two investigational methods. Results demonstrated that a reliable diagnosis could be established with 105 mm photography (sensitivity: 97, 4 p. cent; specificity: 90 p. cent; diagnostic precision: 94 p. cent), that it was economically profitable (economy of 1 m2 of sensitized film surface at each examination), and that productivity was improved by the use of this method.
