Simplified selective renal angiography.

Trends in angiographic techniques over the last 20 years since Odman first developed selective angiography of the branches of the aorta have been to take multiple or serial radiographs rapidly with the aid of various mechanical serial changers. The majority of these move X-ray film (either cut or roll film) between a pair of fluorescent screens, though others (commonly locally-made devices) move cassettes at intervals into the radiographic position. All of these systems use a stationary grid.
