PURPOSE: To characterize intra-abdominal adipose tissue changes in HIV patients with clinical lipodystrophy using a reproducible imaging technique. Materials and methods. 89 HIV patients with clinical lipodystrophy were included. A single axial T1W image was acquired at the mid L4 vertebral level. Two radiologists measured subcutaneous (SAT) and visceral (VAT) adipose tissues using a semi-automated method. Measurements were compared to a matched population (race, sex, age and BMI).
RESULTS: Measurements of abdominal adipose tissue on MRI are reproducible. Three clinical types of lipodystrophy are described in males with increased visceral (VAT) and reduced subcutaneous (SAT) adipose tissues compared to control subjects. Two clinical types of lipodystrophy are described in females with increased visceral (VAT) and unchanged subcutaneous (SAT) adipose tissues.
CONCLUSION: MRI with comparison between HIV patients and normal control subjects is a reproducible method to characterize adipose tissue changes of lipodystrophy and evaluate its severity. Evaluation of a adipose tissue distribution in a large control population would be helpful to the study of metabolic disorders.
