To identify the different layers of the collateral ligaments of the ankle and to develop a dedicated sequence, using routinely in a 1,5 T.

After a pilot study in 2009, we started to realise systematically a 3D proton density weighted sequence without fat saturation, in case of an ankle ligamentary lesion suspicion (1,5T MRI, 8 channels coil). In overall, 127 ankles were explored during a period of 2 years. In about 1/3 of the cases, the complementary arthro-CT scans were realized.

We suggest a 3D sequence that permits to study, in an optimal way, the different ligamentary structures (collateral ligaments, tibiofibular syndesmosis and tarsal interosseous ligaments) and to avoid a systematic arthro-CT scan. Compared to arthro-CT scan, this sequence (in association of the routine sequences) lets a better visualisation of the different ligamentary structures, specially the tibiofibular syndesmosis without any irradiation or infectious risk (even though it’s rare). To better illustrate these points, we present the results of our 2 years experience, using various normal and pathological cases.

The 3D proton density weighted sequence without fat saturation offers a new perspective on MRI to clarify the ankle ligament damage and avoids the realization of a systematic arthro-CT scans.
