Table 4. Benefits of hepatobiliary contrast agents and diffusion-weighted imaging.

MRI with hepatobiliary contrast agents • Higher sensitivity than CT for liver metastases, especially for lesions < 10 mm58 59 • Superior to CT for detecting liver metastases in setting of hepatic steatosis60

MRI with diffusion-weighted imaging • Improved sensitivity and specificity for liver metastases, relative to standard MRI62 63 • Increased accuracy for diagnosis of focal liver lesions, relative to standard MRI64

Abbreviations: CT, computed tomography; MRI, magnetic resonance imaging.
