Figure 11. (a) T₂* weighted axial scan prior to the administration of USIOP showing a 5 mm external iliac lymph node. (b) T₂* weighted axial scan following USIOPs administration showing the node in Figure 11a with persistent high signal suggesting a nodal metastases and the absence of normal iron laden macrophages. (c) Axial non-contrast enhanced CT scan. A fine-needle aspiration of the lymph node demonstrated in Figure 11a was performed under CT guidance. This confirmed nodal metastases from cervical cancer.
