The implantable loop recorder and its mammographic appearance: A case based approach.

The normal radiographic appearance of implantable loop recorders has been illustrated in the radiology literature; however, their mammographic appearance has not been described. Breast imagers should become familiar with the appearance of loop recorders in order to create an accurate report. In this paper we report 3 cases of patients with implantable loop recorders who underwent mammography. We describe the types and components of implantable loop recorders, indications for their placement, and their classic appearance on mammography.
