Follow-up design of unexpected enhancing lesions on preoperative MRI of breast cancer patients

Abstract

We correlated enhancing lesions on MRI with the previously obtained US. SLUS was performed after an average of seven days following the MRI by the same radiologists who had inter- preted the results of MRI. Radiologists carefully scanned breast tissue with the knowledge of enhancing lesions. We considered location, size, and shape of lesions and the relationship between the lesion and other breast landmarks, such as the nipple, subcutaneous fat, glandular tissue and subglandular fat. We also used 3D MR reconstruction images and multiplanar views for po- sition changes between US and MRI. The location of additionally detected enhancing lesions with the index can
