A sonographic-anatomic correlation study was undertaken to define the sonographic appearance of regenerating nodules in cirrhotic livers. Three cirrhotic livers with multiple regenerating nodules were obtained from patients undergoing liver transplantation. Sonograms of the resected livers were made and correlated directly with the anatomic specimens. Using a 3-MHz transducer, no discrete alterations in the echo texture of the livers were seen to correspond to the regenerating nodules. With a 7.5-MHz transducer, discrete islands of liver parenchyma were identified corresponding to regenerating nodules anatomically. The nodules were recognized because of visualization of thin, slightly more echogenic borders, which corresponded pathologically to fibrous and fatty connective tissue surrounding and separating the nodules.
进行了一项超声解剖相关性研究，以确定肝硬化肝脏中再生结节的超声表现。从接受肝移植的患者中获取了三个有多个再生结节的肝硬化肝脏。对切除的肝脏进行超声检查，并将其与解剖标本直接关联。使用3兆赫换能器时，未观察到肝脏回声纹理有与再生结节相对应的离散改变。使用7.5兆赫换能器时，在解剖学上确定了与再生结节相对应的离散肝实质岛。这些结节可被识别是因为可见薄的、回声略增强的边界，在病理上这对应于围绕并分隔结节的纤维和脂肪结缔组织。
