Improved detection of small metastases with optimised SPIO-enhanced T2w GRE imaging. In a patient with colorectal metastases and a fatty liver, right and left lobe lesions (arrows) are well seen on HASTE (a) and IPT1w (b) images. The lesions are isointense against the reduced signal of the adjacent fatty liver on OPT1w (c). Additional small metastases (arrows) not seen on (a–c) are clearly seen on SPIO-enhanced T2w GRE images (d) acquired with a 6 mm slice thickness and fat suppression.
