Synopsis

Keywords: MSK, Nerves, 7T, DESS, peripheral nervesThis study investigated the feasibility of DESS sequence to assess the knee peripheral nerve structures in healthy subjects and patients. The results showed that the nerve imaging quality of DESS sequence was superior to PD sequence in healthy adults. Further, only the isotropic 3D-DESS protocol could clearly visualize the distal peroneal nerve branches and their anatomical course. In patient with peripheral nerves damages, combining the PD and DESS imaging could provide more pathological and anatomical information about the knee peripheral nerve. This suggests that DESS sequence can reliably image the knee peripheral nerves and effectively provide precise knowledge about it.
