Methods 　Eight patients with pathologically proved L SM were enrolled in this study. Eight healthy volunteers were recruited to compose the control group. The MRI appearances were evaluated. The values of PCr , 31 PP , ADP , Pi , PH were measured , and the ratios of Pi/ PCr , Pi/ A TP and PCr/ A TP were calculated using the PMRS spectrum. Results 　There were 2 types of the abnormalities in MRI T1WI : ①increased adipose tissue could be found within the subcuta neous tissue , the intermuscular and intramuscular spaces in 6 cases ; ②absence of normal adipose tissue within the subcutaneous 31 tissue and the intermuscular spaces in 2 cases. As the results of PMRS , the average value of PCr , PCr/ A TP and PP were signifi cantly lower than that of the control group ( P 0. 05) , whereas the average ADP value was signif
