Tissue
repair plays a key role in successful tissue regeneration and involves
various simultaneous processes. In bone regeneration, bone growth in a defect
occurs only in the absence of early fibrous scar formation or collapse of
surrounding tissues into the defect. In this study, a tissue-engineered
construct is inserted into a defect in the rabbit calvarium to provide a
3-dimensional resorbable scaffold that maintains a space for bone growth.
Multicomponent T2 measurements are performed to characterize and
differentiate tissue repair from normal construct resorption.
