Tension‐Dependent Variability and Repeatability of Achilles Tendon UTE‐T 2 * Mapping Using Mono‐ and Bi‐Exponential Models

Key Points

• The study aims to assess the variability and repeatability of UTE-T2* mapping of the Achilles tendon under different tension states.
• Utilized mono- and bi-exponential models for UTE-T2* mapping analysis.
• Standardized tendon tension settings were applied during MRI imaging.
• Quantitative imaging markers were evaluated to relate to tendon integrity.
• UTE-T2* values showed significant variability depending on tendon tension levels.
• Bi-exponential modeling improved repeatability compared to mono-exponential modeling.
• Standardized tension is crucial for consistent quantitative tendon MRI results.
