The spleen‐liver model, as a predictor for contrast‐to‐noise ratio (C/N) in liver metastases, was verified for seven sequences in 22 patients with 70 colorectal metastases. Optimization of conventional spin‐echo, T1‐magnetization‐prepared gradient‐echo and fat frequency‐selective presaturation inversion‐recovery fast spin echo can be done using the spleen‐liver model. C/N of liver‐spleen and liver‐metastases, however, differed significantly on our T1 gradient‐echo and T2‐weighted fast spin‐echo images, with and without fat‐selective saturation. J. Magn. Reson.
