ABSTRACT:
A mammographic medical diagnostic radiographic element is disclosed that produces sharp images and is capable of being processed in less than 60 seconds. Each of imaging and antihalation fully forehardened hydrophilic colloid layer units are coated on the opposite sides of a transparent film support at a hydrophilic colloid coating coverage of less than 55 mg/dm.sup.2. The radiation-sensitive silver halide grains contained in the imaging layer unit are provided by a tabular grain emulsion coated at a coverage capable of providing a maximum density on processing of greater than 3.6. To provide a mid-scale contrast of greater than 3.0 and a lower scale contrast of greater than 2.2, the radiation-sensitive grains (a) exhibit an equivalent circular diameter coefficient of variation grain of less than 15 percent and (b) contain rhodium in a normalized molar concentration of less than 1.times.10.sup.-6 based on silver.
