Paper Abstract

Controlled in vitro studies of breast microcalcification detectability were accomplished using a wide variety of standard and state-of-the-art mammography techniques (conventional and microfocal spot x-ray tubes, screen-film and xeroradiographic recording systems, contact and magnification techniques). Results confirm previous observations that geometric unsharpness is the limiting factor in microcalcification detectability for most conventional mammography systems. Results also indicate superior microcalcification detection for: xeroradiographic > screen-film recording systems, positive-mode > negative-mode xeroradiography, microfocal spot contact > conventional contact techniques, microfocal spot magnification > contact techniques, and 2X magnification > 1.5X magnification techniques. Clinical applications of these findings are discussed.
