Computerized detection of clustered microcalcifications: evaluation of performance on mammograms from multiple centers.

摘要: To investigate the performance of a computerized method for automated detection clustered microcalcifications in digitized mammograms from variety screening centers, authors invited 118 radiologists to bring up five their scientific exhibit at 1993 meeting Radiological Society North America (RSNA). Forty-three 14 sites were brought exhibit, where they and analyzed. Results analysis on RSNA cases compared with those obtained standard database 39 collected two centers. The algorithm images was lower than that achieved database. This due part higher fraction very subtle cases, as well apparent dependence image characteristics (eg, contrast noise), which varied center center. conclude i...
