High-resolution MR lymphography using ultrasmall superparamagnetic iron oxide (USPIO) in the evaluation of axillary lymph nodes in patients with early stage breast cancer: preliminary results

Abstract: 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.

“…The characteristics of the nine 41,42,64,[108][109][110][111][112][113] included studies of MRI for assessment of the axilla are described in Table 8. There were five studies of USPIO-enhanced MRI, [108][109][110][111][112] two studies of dynamic gadolinium-enhanced MRI, 41,113 one study of (non-dynamic) gadolinium-enhanced MRI, 42 and one study of in vivo proton MR spectroscopy.…”

“…The highest mean sensitivity and specificity was recorded for ultra-small paramagnetic iron oxide (USPIO) enhanced MRI, with values of 98 (95 % CI 61-100 %) and 96 % (95 % CI 72-100 %), respectively. Kimura et al [32] found that MRI lymphangiograhy with USPIO, performed on 10 patients with breast cancer, was able to accurately predict all metastatic and normal nodes pre-operatively. However, only Motomura et al [26] performed a breakdown of their identification of metastatic axillary lymph nodes according to micro or macrometastases.…”

“…The ct used in radiotherapy planning has known limitations with respect to lymph node identification and delineation. When added to preoperative diagnostic ct, complementary imaging modalities such as mri and mri with novel lymphotrophic contrast agents such as ultrasmall particles of iron oxide may help to ensure more accurate staging and nodal volume delineation 12 . However, both of the latter modalities are limited, because the positioning of the patient during the scans is different from that used for radiotherapy treatment.…”
