Effect of varying patient positions on liver visualization in a 61-year-old man with chronic HCV infection. Transverse gray-scale US images of the right lobe obtained with the patient in the supine (a) and left posterior oblique (b) positions show severe limitations in liver visualization in the supine position owing to rib shadow (arrow in a), with significant improvement in visualization of the liver parenchyma and diaphragm in b, such that the visualization score improved from C to B.
