Dissociation Between Hepatic Steatosis and Paraspinal Myosteatosis on Quantitative MRI

Hepatic steatosis and paraspinal myosteatosis are metabolically distinct ectopic fat depots. Although paraspinal fat is elevated in diabetes, it does not enhance metabolic risk prediction beyond BMI. These findings support organ-specific lipid pathways and highlight the need for longitudinal and volumetric analyses to clarify their independent clinical roles.
