A magnetic resonance imaging technique based on susceptibility‐induced contrast was used to visualise the spatial distribution of connective tissue in meat. Magnetic resonance imaging of bovine meat samples was carried out with a high‐field 4.7 T imager. Magnetic resonance images obtained with spin‐echo and gradient‐echo sequences were compared to elucidate the role of connective tissue in the additional signal losses observed in the gradient‐echo images. $T_{2}^{\ast}$ maps were reconstructed from the multiple gradient‐echo images, which provide quantitative information. Comparison with histological pictures indicates that these $T_{2}^{\ast}$ maps exhibit the overall organisation of the primary perimysium at the scale of the whole muscle. The distinct perimysial organisation shown between the Gluteo biceps and Pectoralis profundis muscles illustrates the potential of magnetic resonance imaging for characterising the muscle connective tissue structure. © 2000 Society of Chemical Industry
