  • Abstract
    Objective: This study aimed to evaluate the dynamic contrast-en- hanced magnetic resonance imaging (DCE-MRI) in the experimental model of Achilles tendon injury. Methods: Twelve white male adults New Zealand rabbits were divided into two groups, a group with resec- tion of the central portion of the Achilles tendon (n = 8) and a control group (n = 4). Dynamic contrast-enhanced magnetic resonance im- aging (DCE-MRI) was performed 4 weeks after the surgical procedure, followed by histological analysis of the tendons. Results: The main finding of this study was the difference (p < 0.001) in peak contrast enhancement on DCE-MRI, which demonstrated that the operated group had greater contrast uptake. The operated tendons showed histological disruption of their architecture, and cluttered appear- ance of tendinous fibers, with vascular and fibroblast proliferations. Conclusion: DCE-MRI is a technique with a potential to demonstrate changes in the vascularity pattern of the Achilles tendon before and after operation. DCE-MRI has a potential to be used in studies of tendinosis diagnosis and surgical follow-up. Level of evidence II, Experimental Study.
