Volume of the Achilles tendon measured on magnetic resonance images before (MRI 0) and one week (MRI I) and one year (MRI IV) after the transverse core biopsy procedure
| MRI 0 | MRI I | Δ volume I | p Value | MRI IV | Δ volume II | p Value | |
|---|---|---|---|---|---|---|---|
| The tendon volume in five different sagittal MRI sequences is given in cm3. The percentage change in volume one week (Δ volume I) and one year (Δ volume II) after the biopsy is also shown. The non-parametric Wilcoxon matched pairs test was used. | |||||||
