Establishing Normative Hepatic Dimensions in Southern Libya: A Cross-Sectional Sonographic Study

Purpose: The aim of this study is to investigate and addresses the critical gap in normative hepatic measurements for Southern Libya. 
Materials and Methods: The study conducted a prospective cross sectional analysis of 101 outpatients (50 males, 51 females; age range 8–100 years) at Tasawah General Hospital between November 2025 and January 2026. Hepatic dimensions were quantified via standardized ultrasonography along the midclavicular line (MCL). Anthropometric parameters and demographic variables were simultaneously recorded. Pearson correlation coefficients assessed relationships between somatic and hepatic measurements. 
Results: Mean hepatic length demonstrated remarkable consistency across sexes: 13.8 cm (SD ±2.16) in males versus 13.96 cm (SD ±2.08) in females. Moderate-to-strong positive correlations emerged between hepatic size and body mass (males: r=0.66; females: r=0.54) and stature (males: r=0.56; females: r=0.49). The 20–40-year demographic represented the largest cohort (40.6%), with balanced sex distribution (49.5% male, 50.5% female). 
Conclusion: Sonographic evaluation provides reliable, non-invasive quantification of hepatic dimensions. Our findings establish the first documented reference intervals for this geographic region, emphasizing the necessity of incorporating somatic variables into hepatic assessment protocols. These data reduce diagnostic uncertainty and support early detection of hepatomegaly or parenchymal atrophy in clinical practice. (Open J Med Radiol 2026;1:3-8)
