Accurate noninvasive measurement of the volume of the liver has many potential clinical applications and is an important element in the preoperative evaluation of the liver transplant recipient. Helical (or spiral) computed tomography (CT) has theoretical advantages over conventional CT in this application because the entire liver can be imaged in a single breath-hold, limiting inaccuracies related to patient motion and respiratory variation.
We compared liver volumes measured by conventional CT and helical CT in 22 patients undergoing preoperative evaluation for liver transplantation.
The mean volume for helical CT is 1328 ml (SD 405) and conventional CT is 1323 ml (SD 417).
We found no significant difference between the helical CT and conventional CT volumes for each patient.
准确无创地测量肝脏体积有许多潜在的临床应用，并且是肝移植受者术前评估的重要因素。在这项应用中，螺旋（或容积）计算机断层扫描（CT）相较于传统CT具有理论优势，因为整个肝脏可以在一次屏气过程中成像，从而限制了与患者运动和呼吸变化相关的不准确性。
我们比较了22例接受肝移植术前评估患者的传统CT和螺旋CT测量的肝脏体积。
螺旋CT测量的平均体积为1328毫升（标准差405），传统CT测量的平均体积为1323毫升（标准差417）。
我们发现每位患者的螺旋CT和传统CT测量的肝脏体积之间无显著差异。
