Tibialis anterior muscle spectra from

The first peculiarity of muscle spectra is the possibility to differentiate two lipid compartments. Furthermore, the characteristics of the lipid signals depend on the chosen particular muscle and its orientation with respect to the magnetic field. Figure 15 shows a typical spectrum of the tibialis anterior muscle (TA) in comparison with a spectrum from the fatty bone marrow of... 

Fig. 30. Thirteen-year-old boy with desmin storage myopathy, (a) The T weighted image shows an atrophy of the tibialis anterior muscle (with the volume element indicated) and a fatty degeneration of the soleus muscle (arrow), (b) The spectrum from the tibialis anterior muscle shows prominent EMCL. TMA is reduced as indicated in the area of the 5-fold magnification.

X 11 X 20) mm. (a) Cross-section of the human lower leg of a volunteer. Two volume elements in musculature and one voxel inside the tibial bone marrow are indicated, (b) Spectrum recorded from the tibialis anterior (TA) muscle shows low lipid content of approximately 1% volume fraction, (c) Spectrum from the soleus (SOL) muscle indicates higher lipid content than in TA. (d) Spectrum from yellow bone marrow with dominating signal from fatty acids in triglycerides.
