Anatomy of picture archiving and Communications systems: nuts and bolts--image acquisition: getting digital images from imaging modalities.

abstract：:A study was conducted to evaluate the sensitivity of computer-aided detection (CAD) with full-field digital mammography in detection of breast cancer, based on mammographic appearance and histopathology. Retrospectively, CAD sensitivity was assessed in total group of 152 cases for subgroups based on breast density, ma...
