Surgeon peer network characteristics and adoption of new imaging techniques in breast cancer: A study of perioperative MRI

Perioperative MRI has disseminated into breast cancer practice despite equivocal evidence. We used a novel social network approach to assess the relationship between the characteristics of surgeons’ patient‐sharing networks and subsequent use of MRI.
