Fig. 1B. 62-year-old woman with hypovascular liver metastases from
breast cancer and stable disease. Baseline contrast-enhanced transverse
T1-weighted spoiled gradient-echo images (150/4.1) were obtained immediately
(B), 45 sec (C), and 90 sec (D) after administration of
contrast material. Faint ring lesion enhancement is less intense than
enhancement of renal cortex and pancreas on immediate contrast-enhanced image
(B). Note that lesion becomes more conspicuous at 45- and 90-sec images
(C, D), which is characteristic of hypovascular metastases.
