Diffusion-weighted MRI in a liver protocol: Its role in focal lesion detection

Figure 4 Metastasis in the IV segment. A: A metastatic lesion in colon carcinoma is depicted in the most caudal area of the IV liver segment, it was well depicted in the fat-suppressed fast spin-echo T2-weighted sequence (arrow); B: In the gadolinium-enhanced acquisition (arrow); C: The lesion is poorly represented in the diffusion-weighted imaging, covered by magnetic susceptibility artifacts due to the adjacent intestinal loop (arrows); D: Delayed imaging after gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid confirmed the metastatic lesion (arrow).
