The Fat fraction and morphological features of lateral pterygoid muscle in normal position disk (NP) group, anterior disk displacement with reduction (ADDWR) group and anterior disk displacement without reduction (ADDWOR) group. (a) There is a significant difference of fat fraction between NP group and ADDWOR group. (b, c) There is no significant difference of length and width among three groups. (d) There is a significant difference of thickness between NP group and ADDWOR group, ADDWR group and ADDWOR group
