Diagnostic performance of abbreviated gadoxetic acid-enhanced magnetic resonance protocols with contrast-enhanced computed tomography for detection of colorectal liver metastases

Figure 4 An 86-year-old woman with a colorectal liver metastasis in segment 3, measuring 2. 8 mm in diameter (arrows). A: The metastasis (arrow) appears indistinct on single-shot fast spin echo T2-weighted imaging; B: The metastasis (arrow) appears indistinct on fat-suppressed fast spin echo T2-weighted imaging; C: The metastasis (arrow) is clearly depicted as an area of hyperintensity on diffusion-weighted imaging; D: The metastasis (arrow) is clearly depicted as an area of hypointensity on hepatobiliary-phase imaging. The lesion was scored 4 or 5 by one reader in each abbreviated enhanced magnetic resonance imaging (Ab-MRI) protocol, and was missed by the other reader in Ab-MRI protocol 1 and 2.
