There are many species or tissue components which have very short T2 relaxation times and so cannot be detected with conventional magnetic resonance imaging (MRI) sequences. These include cortical bone, meniscus, ligaments, aponeuroses, the Achilles tendon, etc. High resolution in vitro imaging has been reported, together with in vivo imaging with moderate resolution and especially limited short T2 image contrast. Here we report 3D high resolution and contrast imaging of these short T2 species in vivo on a clinical 3T MR scanner.
