From the Research
The normal dimensions of the liver in adults are approximately 20-22.5 cm in width, 15-17.5 cm in its anteroposterior dimension, and 10-12.5 cm in height, with a normal liver span being 6-12 cm in the midclavicular line, as supported by the most recent study on liver size assessment using ultrasonography 1.
Factors Affecting Liver Size
The liver size can vary based on several factors including:
- Body size
- Age
- Gender
- Body habitus
- Fatty liver
- Metabolic syndrome
- Waist-to-hip ratio
Assessment of Liver Size
The liver size can be assessed clinically by measuring liver span during percussion, with a normal span being 6-12 cm in the midclavicular line. Radiologically, liver size is more accurately determined using ultrasound, CT, or MRI.
Importance of Normal Liver Dimensions
Understanding normal liver dimensions is important for detecting hepatomegaly (enlarged liver) or atrophy, which can indicate various pathological conditions including fatty liver disease, hepatitis, cirrhosis, or malignancy.
Recent Studies
A recent study published in 2021 found that ursodeoxycholic acid treatment can improve liver enzymes and hepatic steatosis in patients with nonalcoholic fatty liver disease 2. Another study published in 2016 found that ursodeoxycholic acid treatment can reduce liver cyst volume growth in patients with autosomal dominant polycystic kidney disease 3. However, these studies do not provide information on normal liver dimensions.
Conclusion Not Applicable
Instead, the most relevant information is that the normal liver dimensions are crucial for detecting liver diseases, and the liver size can be assessed using various methods, including ultrasonography, which is a simple and non-invasive method 1.
