Fig. 2E —61-year-old woman with breast cancer. Because of low
lesion-to-liver contrast and interfering high signal intensity of intrahepatic
vessels, 7- and 11-mm metastatic lesions (arrows) were frequently
missed by observers on T2-weighted turbo spin-echo images (A–E).
F and G clearly show both lesions. Diffusion gradient with b
value of 600 s/mm2 (G) induces increased background noise
but suppresses signal intensity of bile ducts. Thus metastatic lesions remain
only hyperintense structures within hepatic parenchyma. T2-weighted
respiration-triggered STIR MR image.
