Chronic kidney disease (CKD) is associated with reduction in skeletal muscle quality from the interplay of inflammation and malnutrition, resulting in reduced exercise capacity. Muscle quality can be assessed by texture analysis of images acquired by 1H-Magnetic Resonance Imaging (MRI). The study objective is to compare muscle quality using MR images between healthy controls, CKD, hemodialysis (HD) and peritoneal dialysis (PD) patients. We hypothesize that progressive CKD and dialysis therapy are associated with muscle quality changes that can be detected by texture analysis.


1H T1-weighted images of the calf were acquired on control, CKD, HD, and PD patients. Mid-slice was used to delineate the gastrocnemius and soleus muscle. Heterogeneity of the muscle was quantified by the standard deviation (SD) within the regions. One-way ANOVA was used to assess significance between groups. Pearson correlation analysis was completed between estimated glomerular filtration rate (eGFR) and SD of the muscles at CKD stages 1-5 (HD and PD cohort excluded).


Refer to Figures 1 and 2.


Homogeneous characteristics seen in CKD cohort may be indicative of muscle wasting and fibrosis. MRI based quality assessment may provide potential non-invasive evaluation of the uremic state on skeletal muscle structure and function.
