[Magnification mammography using 0.1 mm microfocus. Comparison of grid and spot-view magnification].

Phantom measurements of resolution and dosimetry of 0.1 mm microfocus spot magnification mammography and 0.3 mm grid technique using different film-screen systems form the basis of this study. The diagnostic efficiency of spot views with these methods is evaluated according to the detection and analysis of microcalcifications, and the assessment of tumor margins.
