title: An assessment of intravenous urogram imaging using 100 mm and conventional films.
abstract: A clinical trial was designed to compare the amount of useful diagnostic information obtained from the ten-minute (24 x 30 cm) film of an IVU when using either indirect (100 mm) or conventional radiography. The films for 50 patients were independently examined by ten radiologists. Eight observers considered conventional radiography to be significantly better than indirect (100 mm) radiography, P less than 0.05, and two observers considered that there was no significant difference. Possible applications of indirect radiography are briefly described.
