| 目的 探讨多层螺旋CT(MSCT)半自动法测量右半肝体积准确性及在活体肝移植(LDLT)中的应用价值。方法 对50例供体术前行MSCT四期增强扫描,用半自动法(IQQA-liver肝脏诊断辅助分析系统)于门静脉期测量右半肝体积与术中水测法所测体积进行相关分析及student's t检验。结果 半自动法和术中水测法所测肝体积分别为(770.36±151.19)cm3和(669.84±144.77)cm3;半自动法与术中水测法所测肝体积呈正相关(r＝0.86,P<0.05);半自动法所测肝体积与术中水测法所测肝体积差值为101.36 cm3(95%可信区间为79.06~123.66 cm3)。结论 半自动法测量LDLT右半肝体积有较高准确性和可重复性,具有可靠的临床应用价值。 |

| Objective To evaluate the accuracy of multi-detector spiral CT (MSCT) semi-automated volumetric measurement of right lobes and its value in living donor liver transplantation (LDLT). Methods Fifty donors underwent 4 phases MSCT. Pre-operative liver volumes of IQQA-liver semi-automated measurement (Vauto) in portal vein phase were compared with intra-operative measurement (Voper) by means of water displacement. Correlation co-efficient and student's t tests were used for statistical analysis. Results Pre-operative and intra-operative measurements of grafts resulted in a mean volume of (770.36±151.19)cm3 and (669.84±144.77)cm3, respectively. Corresponding pre- and intra-operative data correlated significantly with each other. There was positive correlation between liver volume measured according to Vauto and Voper (r=0.86, P<0.05). The mean difference between Vauto and Voper was 101.36 cm3, and 95% confidence interval was 79.06—123.66 cm3. Conclusion Semi-automated method can accurately and reliably measure the liver volume of right lobes. |
