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

Figure 5 A 59-year-old man with a colorectal small liver metastasis (arrows) and a small simple hepatic cyst (arrowheads) that were 4. 1 mm and 5.5 mm, respectively. A: The metastasis (arrow) appears indistinct, whereas the cyst (arrowhead) is clearly depicted as an area of hyperintensity on single-shot fast spin echo T2-weighted imaging; B: The metastasis (arrow) is depicted as mild hyperintensity, and the cyst (arrowhead) is clearly depicted as an area of hyperintensity on fat-suppressed fast spin echo T2-weighted imaging; C: The metastasis (arrow) is clearly depicted as an area of hyperintensity, and the cyst (arrowhead) is not depicted on diffusion-weighted imaging; D: The metastasis (arrow) and the cyst (arrowhead) are clearly depicted as an area of hypointensity on hepatobiliary-phase imaging. The metastasis (arrows) was scored 5 by all four readers. The cyst (arrowheads was scored 1 or 2 by all four readers.
