Assessing adequacy of mammographic image quality.

High-quality mammographic images enhance the radiologist's ability to interpret mammograms with high sensitivity for detecting abnormalities and high specificity for classifying lesions suspicious for malignancy. In addition to proper exposure, contrast, resolution, compression, and positioning, high-quality mammographic images must be accompanied by pertinent history and available comparison images. To avoid negating the benefits of technically ideal images, mammograms must be viewed under optimal viewing conditions. Constant attention to quality control, with every image evaluated for adherence to strict technical standards, is essential for maintaining image quality.
