Fig. 2B —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 fat-suppressed breath-hold MR image.
