Texture analysis (TA) combined with dedicated gradient echo magnetic resonance imaging (MRI) at high field provides specific parametric $T_{2}^{*}$ maps of connective tissue and allows statistical analysis of the resulting texture. The present study clearly demonstrates that MRI‐TA of bovine meat can discriminate between muscle types Gluteo biceps and Pectoralis profundus, and between genotype origins corresponding to the mutation on the myostatin gene: normal +/+, heterozygous mh /+ or homozygous double‐muscled mh / mh Belgian White Blue bulls. Values of interclass separations reflect the significantly different collagen and fat contents in these genotypes. To our knowledge, no previous study has demonstrated such a correlation between MRI texture and genetics‐related modifications. Copyright © 2004 Society of Chemical Industry
