Abstract

Background The purpose of this study was to examine the utility of high-resolution magnetic resonance (MR) lymphography using ultrasmall superparamagnetic iron oxide (USPIO) in the evaluation of axillary lymph nodes in patients with early stage breast cancer.Methods Ten women with breast cancer without swollen axillary lymph nodes were enrolled in this study. High-resolution MR lymphography was performed 24 h after administration of USPIO. On the MR examination, a 3-inch surface coil was placed on the sentinel lymph node (SLN) parts as defined by a radioisotope (RI) scintigraphy method, and T2*-weighted (T2*W) and T1-weighted (T1W) images were obtained. Detected nodes were differentiated as normal or diseased nodes by the enhancement patterns. The day after MR examination, SLN biopsy (SNB) was performed. The imaging results were compared to the histopathologic findings.Results On MR images, the mean number of detectable nodes was 7.9 per patient. Eight patients who histopathologically had no metastatic lymph nodes were diagnosed as nonmetastatic and two patients who had 3- and 6-mm metastatic areas in the node, respectively, were diagnosed as metastatic preoperatively. No side effects were noted.Conclusions High-resolution MR lymphography using USPIO enabled us to obtain good axillary lymph node evaluation results. These results suggest that this method of imaging may contribute to better preoperative lymph node staging.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
