超声和计算机断层扫描测量活体肝脏体积。将获得的数据与原位肝移植时手术切除的相同肝脏的重量和体积进行比较。肝脏重量和体积之间的关系被发现在16倍的重量范围和19倍的体积范围内是线性的。超声结果与直接获得的结果更接近。这些数据表明，在可接受的范围内，两种方法都可以确定肝脏的体积或重量。然而，超声技术比计算机断层扫描方法更准确，因为它允许使用肝脏的矢状面扫描，这优于计算机断层扫描仪所需的横向扫描技术。此外，这些结果表明，这些方法可能会在未来应用，以更好地匹配原位肝移植的供受者。
Ultrasonography and computed tomography were used to determine hepatic volume in vivo. The data obtained were compared with the weight and volume of the same livers after surgical removal at the time of orthotopic hepatic transplantation. The relationship between hepatic weight and volume was found to be linear over a 16-fold range of weights and a 19-fold range of volumes. The sonographic results more closely paralleled the results obtained directly. These data demonstrate that both methods can determine, within acceptable limits, hepatic volume or weight. The sonographic technique, however, is more accurate than the computed tomography scan method as it allows the use of sagittal scanning of the liver, which is superior to the transverse scanning technique required by the computed tomography scanner. In addition, these results demonstrate that these methods might be applied in the future for better matching of donors and recipients of orthotopic liver transplants.
