Figure 8.

Value of dynamic high-resolution T1w imaging with ferucarbotran for depicting small metastases. Multiple small metastases (many not visible on unenhanced images) are highly conspicuous on 3D FS T1w GRE imaging (effective slice thickness 2.5 mm) obtained 45 s after bolus injection of ferucarbotran ((a) and (b)). Note the relatively weak T1 effect resulting in isointensity of the background liver and vessels. The lesions are also well seen on corresponding T2w GRE images (c–e) obtained 10 minutes after (a) and (b).
