Purpose To assess the potential clinical utility of in vivo susceptibility‐weighted imaging and quantitative susceptibility mapping of growth cartilage in the juvenile human knee at 7 T. Methods High‐resolution gradient‐echo images of the knees of six healthy children and adolescents aged 6 to 15 were acquired with a 28‐channel coil at 7 T. Phase images from the coils were combined using a short echo‐time reference scan method (COMPOSER). Results Veins oriented perpendicular to the static B 0 field appeared doubled in susceptibility‐weighted imaging, but not quantitative susceptibility mapping. Veins and layers in the cartilage were visible in all children up to the age of 13. Conclusions Phase imaging using susceptibility‐weighted imaging and quantitative susceptibility mapping allows the in vivo visualization of veins and layers in human growth cartilage.
