Detection of Breast Cancer With Addition of Annual Screening Ultrasound or a Single Screening MR I to Mammography in Women With Elevated Breast Cancer Risk.

The article discusses a substudy undertaken to assess the rate and stage of cancers detected with a single screening magnetic resonance imaging (MRI). Participants to the study included women who were asymptomatic and presented for routine annual mammography with heterogeneously dense or extremely dense breast tissue with at least one other risk factor for breast cancer. It suggests that the addition of screening MRI rather than ultrasound to mammography in a population of women at intermediate risk with dense breast may not be proper specially when the current high false-positive rates, cost and reduced tolerability of MRI are considered.
