From the Guidelines
No, the liver's inferior marginal angles are normally blunt, not sharp, on ultrasound [ 1 ]. Sharp angles may indicate liver pathology, such as cirrhosis or metastasis, and warrant further evaluation. In a normal liver, the inferior margin is typically smooth and rounded.
Key Points
- The liver's inferior margin is usually visualized using a subcostal or intercostal approach [ 1 ].
- The liver margin should be maintained within the field of view on the screen [ 1 ].
- A combination of subcostal and intercostal windows may be necessary to visualize the liver and surrounding structures [ 1 ].
- The appearance of the liver's inferior marginal angles can be an important indicator of liver health, with sharp angles potentially indicating underlying pathology [ 1 ].
From the Research
Liver Inferior Marginal Angles on Ultrasonography
- The provided studies do not directly address the sharpness of liver inferior marginal angles on ultrasonography 2, 3, 4, 5, 6.
- However, the studies discuss the use of ultrasonography in evaluating liver morphology and function 2, 5, 6.
- One study notes that ultrasonography can be used to evaluate liver segments and anatomy 5, but it does not specifically mention the inferior marginal angles.
- Another study discusses the agreement between clinical measurements of liver size and ultrasound findings 4, but it does not address the sharpness of liver inferior marginal angles.
- Overall, there is limited information available on the sharpness of liver inferior marginal angles on ultrasonography based on the provided studies 2, 3, 4, 5, 6.
