The development of cineroentgenographic methods for following changes in left ventricular, and other chamber volumes has been reviewed. Since injections of contrast media and repeated exposure to radiation are to some extent hazardous, and since cineroentgenographic methods can never provide data for more than a small number of consecutive cycles, they cannot be considered ideal. The ideal method would require no injection, would subject the subject to no hazard, and should be applicable for long periods of time, regardless of the position or activity of the subject. To date, no such system has been devised. For the foreseeable future, carefully designed multiplane cineroentgenographic methods, combined with scanning devices for digitizing data obtained from film images, offer the greatest promise despite inherent defects.
