[High-grade direct roentgen magnification--a new possibility in skeletal diagnosis?]

High-grade direct X-ray magnification represents a new technique. Its possibilities are demonstrated taking as example a comparison between histological and directly X-ray magnified images of bone tumour specimens. With its method, which has previously not been introduced, it is possible to obtain images of anatomical structures the display of which was previously the preserve of histological techniques. The still high local radiation exposure currently limits use in the main to basic research.
