Difficulties in the preoperative assessment of tumor size and extent result in a positive
pathologic margin in up to 70% of patients undergoing breast conservation surgery.
Although positive margins usually require reexcision, the location and extent of surgery
required are often difficult to establish by current imaging techniques. We investigated the
accuracy of three-dimensional rotating delivery of excitation off resonance (3D RODEO) MR
imaging of the breast in revealing the presence and extent of residual tumor within the …

In their article on detecting residual breast tumors after surgery F1], Soderstrom et al.
describe their experience using MR imaging to determine the extent oftumor in patients who
have newly diagnosed breast cancer. However, the authors include patients who have not
yet had reexcision or definitive treatment as well as patients who have undergone radiation
therapy. The authors interchange the terms“residual tumor” and “recurrent tumor.”
Presumably, for all of these patients imaged within 10 months, tumor in the breast is …
