The manner in which imaging patterns change over the disease course and with increasing disability in dysferlinopathy is not fully understood. In the study, fibroadipose infiltration of 61 muscles was scored based on whole-body MRI of 33 patients with dysferlinopathy.
Disease duration is related to infiltration of infraspinatus, teres major-minor and supraspinatus muscles. MFM-D1 decreases with higher infiltration of teres major-minor, triceps and sartorius.
