T1W\u2010SE, T2W\u2010FSE, and 3D\u2010PSIF were used before and 24\u201336 hours after MRI with ultra small particles of iron oxide (USPIO) was performed. A total of 52 lymph nodes (LNs) in nine patients (25 benign, 27 malignant) were evaluated by two readers who were visually and quantitatively blinded to the histology. Combinations of the following diagnostic parameters were compared using logistic regression analysis: the short\u2010axis diameter of the LN, the signal distribution of the LN on postcontrast agent MRI (homogeneous or heterogeneous), and qualitatively and quantitatively determined signal changes of the LN following administration of contrast agent in the three evaluated sequences.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Using pre\u2010 and postcontrast data, the optimized accuracy based on the statistically most significant parameters (LN diameter &gt; 6 mm, visual assessment of signal change on T2W\u2010SE) was 87% (81% sensitivity, 92% specificity). Precontrast data alone yielded 75% accuracy (63% sensitivity, 86% specificity). Postcontrast data alone yielded 75% accuracy (56% sensitivity, 96% specificity).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Based on our results, USPIO\u2010MRI improved the diagnosis of metastatic axillary LNs compared with precontrast MRI alone. Both pre\u2010 and postcontrast studies are needed. T1W\u2010SE and T2W\u2010PSIF did not yield significant additional information. This study may help to further improve the technique of USPIO imaging. J. Magn. Reson.
