Reliability and Repeatability of Diffusion Tensor Imaging in Healthy and Pathological Patellar Tendons.

ABSTRACT: Patellar tendinopathy and bone-patellar tendon-bone autograft harvest for anterior cruciate ligament reconstruction are tendon injuries that impact long-term knee health. Diffusion tensor imaging (DTI) is a non-invasive magnetic resonance imaging (MRI) based approach with the potential to assess tendon microstructure. This study aimed to determine the inter-rater reliability of segmentations and test-retest repeatability of DTI metrics in pathological and contralateral patellar tendons. Ten participants received two bilateral knee MRI scans within a 7-day period. 3D CUBE proton density weighted images and DTI were acquired. Two raters segmented each of the first scans, and one rater segmented the second scans. Tendon masks were then bisected into proximal and distal regions of equal length
