Partial SI decrease in metastatic lymph node in a woman aged 45 years with primary stage pT2N1 tumor. Sagittal nonenhanced (A) and ultra‐small superparamagnetic iron oxide (USPIO)–enhanced (B) T2‐weighted fast spin echo magnetic resonance (MR) images (7,600/120) as well as nonenhanced (C) and USPIO‐enhanced (D) T2*‐weighted fast field echo MR images (683/14) of left axilla show a 1.4 × 0.9 cm metastatic lymph node (large arrow) with partial signal intensity (SI) decrease after USPIO administration. Adjacent nonmetastatic node (small arrow) shows homogeneous SI decrease after USPIO administration. Primary tumor is seen.
