Bovine and human mensicus specimens were examined at
11.7T in order to demonstrate the vasculature of the
meniscus. Multiple spin echo and gradient echo sequences
showed high signal branching structures consistent with
blood vessels and separable from radial ties or fibers.
The vessels were generally interposed between radial and
circumferential fibers and did not involve the more
cartilaginous regions. The results are consistent with
previous angiographic and microscopic studies and show
that it may be possible to demonstrate vascular features
at higher fields using clinical systems.
