Fig. 4 —
67-year-old man with prostate cancer (serum prostate-specific antigen level, 56.76 ng/mL).
A, Axial T2*-weighted MR image obtained before ferumoxytol injection shows left iliac chain adenopathy (arrow).
B and C, T2*-weighted MR images obtained 24 (B) and 48 (C) hours after ferumoxytol injection show lack of ferumoxytol uptake within left iliac chain adenopathy (arrows). D, Follow-up CT image obtained 6 months after diagnosis and after androgen deprivation therapy shows significant decrease in size of left iliac chain adenopathy (arrow) to current size of 1 × 0.6 cm compared with size on baseline image (A) (1.8. x 1.3 cm). Findings are consistent with metastatic disease within this left iliac chain adenopathy.
