Increase in perceived case suspiciousness due to local contrast optimisation in digital screening mammography.

Objectives: To determine the influence of local contrast optimisation on diagnostic accuracy and perceived suspiciousness of digital screening mammograms.

Methods: Data were collected from a screening region in the Netherlands and consisted of 263 digital screening cases (153 recalled,110 normal). Each case was available twice, once processed with a tissue equalisation (TE) algorithm and once with local contrast optimisation (PV).

Breast cancer screening results 5 years after introduction of digital mammography in a population-based screening program.

Purpose: To compare full-field digital mammography (FFDM) using computer-aided diagnosis (CAD) with screen-film mammography (SFM) in a population-based breast cancer screening program for initial and subsequent screening examinations.

Materials And Methods: The study was approved by the regional medical ethics review board. Informed consent was not required.
