Bone marrow changes on STIR MR images of asymptomatic feet and ankles


Zubler, Veronika; Mengiardi, Bernard; Pfirrmann, Christian W A; Duc, Sylvain R; Schmid, Marius R; Hodler, Juerg; Zanetti, Marco (2007). Bone marrow changes on STIR MR images of asymptomatic feet and ankles. European Radiology, 17(12):3066-3072.

Abstract

The purpose of this study was to evaluate the prevalence, pattern and size of bone marrow changes on short-tau inversion recovery (STIR) magnetic resonance (MR) images of asymptomatic feet and ankles. In 78 asymptomatic volunteers (41 women, 37 men; median age 47years; range 23-83years) sagittal STIR MR images of hindfoot and midfoot were reviewed for various patterns of high signal changes in bone marrow. The size of these bone marrow changes was measured, and signal intensity was rated semi-quantitatively using a scale from 0 (=normal) to 10 (=fluid-like). Fifty percent (39/78) of all volunteers had at least one bone marrow change. Thirty-six percent (28/78) of all volunteers had edema-like changes, 26% (20/78) had necrosis-like changes, and 5% (4/78) had cyst-like changes. The long diameters of all changes varied between 4mm and 16mm (median 7.5mm). The median signal intensity for all changes was 5.0 (range 1-10). Bone marrow changes on STIR MR images are commonly detected in asymptomatic feet and ankles. However, such changes tend to be small (<1cm) or subtle
