A series of ultrasound strain images of a breast lesion are acquired along with corresponding B-mode images using a real-time ultrasound strain imaging system and a free-hand technique. A visual assessment of the lesion is made by the sonographer after image acquisition. A conspicuity metric is calculated from the strain images based on the weighted sum of lesion contrast values in each strain image. The weighting of each lesion contrast value is based on observed characteristics of malignant lesions in a series of strain images. Diagnosis is made based on the visual assessment and the conspicuity metric
