Soleus muscle spectra from

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. 

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.

Fig. 16.79 a-c. Partial rupture of the Achilles tendon. Longitudinal 12-5 MHz US images demonstrate a spectrum of appearances of partial-thickness tears of the Achilles tendon in three different cases, all surgically proven, a The echotexture of the posterior half of the Achilles tendon is abnormally hypoechoic (asterisks) with loss of the fibrillar pattern, b A hypoechoic interstitial defect (asterisks) in the longitudinal direction is visible within the tendon substance. C, calcaneus c The anterior border of the Achilles tendon is wavy (arrows) and the echotexture appears diffusely hypoechoic. In this case, there wis discontinuity of the anterior fibers from the soleus muscle...
