title: Low dose urography with a low osmolar contrast medium.
abstract: In a double blind study of 100 consecutive patients routinely referred for urography, a conventional contrast medium (Isopaque cerebral) was compared at a dose of 180 mg I/kg body weight with a low osmolar contrast medium (Hexabrix 160) at a dose of 90 mg I/kg body weight. In spite of 50 per cent dose reduction, equally good diagnostic effect was achieved with Hexabrix as with the conventional contrast medium.
