Figure 4.
Relationship between IMCL and EMCL CH2 peak measured by 1H MRS and mean MA determined by CT in the soleus muscle (r = −0.64 for IMCL and −0.37 for EMCL; p < 0.01; n = 0.51). IMCL and EMCL are expressed in arbitrary units relative to a peanut oil phantom that is positioned external to the calf. A low mean MA reflects a higher fat content.
