Which value represents a typical spatial resolution for screen-film mammography?

Explanation:
Spatial resolution is about how finely details can be distinguished in an image, measured in line pairs per millimeter. In screen-film mammography, resolving small features like microcalcifications is essential, so the system is described by its ability to separate about 15 line pairs per millimeter. This level of detail reflects the balance between film screening, screen speed, and geometric factors to produce sharp, diagnostically useful images. Values significantly lower would blur tiny calcifications, while a much higher number isn’t typical for standard screen-film equipment. Therefore, 15 lp/mm best represents the usual capability.
