UTE T2* mapping of tendinopathic patellar tendons: an MRI reproducibility study
There is currently a lack of imaging modalities that can be used as a sensitive measure in tendinopathy.
Tendinopathy, also called tendinosis, refers to the breakdown of collagen in a tendon. This causes burning pain in addition to reduced flexibility and range of motion. While tendinopathy can affect any tendon, it’s more common in the: Achilles tendon. rotator cuff tendons.
As newer imaging becomes available, it is important to assess its sensitivity and reproducibility of the measurements.
Recent findings suggest the applicability of ultra-short echo time (UTE) magnetic resonance imaging (MRI) T2* mapping in tendons.
These data demonstrate a small bias between repeated measurements for UTE T2*, but with a very low associated mean difference (3.7%) between the two tests.
The high ICC values and low typical error % demonstrate reproducibility of repeated T2*-mapping sessions.
The method showed substantial intra- and inter-observer reproducibility for T2* values proving feasibility for use of UTE T2* mapping in research and clinical practice.
