Biointegration of massive bone allografts: imaging and histological studies in cat.
BIOMATERIALS(1990)
Abstract
A study was carried out in a cat model to compare three imaging methods (X-ray, bone scintigraphy (BS) and magnetic resonance imaging (MRI] in order to assess the healing of bone allografts. X-ray remains the first technique to proceed, for morphological information and control of devices. BS is very sensitive although unspecific and difficult to quantify in exploration of bone reconstruction. It may be a useful complement of X-ray methods in some pathological circumstances (stress fracture, infection, non union). MRI is a very sensitive exploration of the bone marrow, but not of the cortical bone. In its present state it is of little value in bone graft imaging because of its low specificity and because of metallic artefacts (material, micro particles).
