Abstract

Objectives: To evaluate the effect of slice thickness on multidetector computed tomography-based preoperative liver volumetry, and to compare the time consumed during volumetry between thin and thick slices.

Methods: The retrospective study was conducted at the Pakistan Kidney and Liver Institute and Research Centre, Lahore, Pakistan, and comprised data from September 2022 to January 2023 of patients who underwent donor hepatectomy. Liver volumetry was done on thick 5mm and thin 0.625mm slices, and the consumed time was calculated. The calculated volumes were then compared to the actual per-operative graft volume. Data was analysed using SPSS 20.

Results: Of the 30 donors, 20(66.7%) were males and 10(33.3%) were females. The overall mean age was 26±6.25 years (range: 19-44 years. The mean estimated graft volume on thick slices was 668.57±169.83g compared to 693.70±174.78g on thin slices (p>0.05). The time taken to calculate estimated graft volume on thick slices was 7.29±0.97 minutes compared to 44.07±4.78 minutes on thin slices (p<0.05). The mean actual per-operative graft volume was 632.40±160.03.

Conclusions: There was no significant difference between the volumes calculated on thick and thin slices, but there was significant difference in time taken for volumetry.

活体肝移植ct肝体积测量：切片厚度对体积计算的影响。

目的：评价多层计算机断层扫描对术前肝脏体积测量的影响，并比较薄、厚切片在体积测量中所花费的时间。方法：回顾性研究在巴基斯坦拉合尔的巴基斯坦肾脏和肝脏研究所和研究中心进行，包括2022年9月至2023年1月接受供肝切除术的患者的数据。分别对厚5mm和薄0.625mm切片进行肝脏体积测定，计算消耗时间。然后将计算的体积与实际的术前移植物体积进行比较。数据采用SPSS 20进行分析。结果：30例献血者中，男性20例（66.7%），女性10例（33.3%）。总体平均年龄26±6.25岁（范围19 ~ 44岁）。厚片移植体平均体积为668.57±169.83g，薄片移植体平均体积为693.70±174.78g （p < 0.05）。厚片计算移植物体积的时间为7.29±0.97 min，薄片计算移植物体积的时间为44.07±4.78 min (p结论：厚片与薄片计算移植物体积的时间无显著性差异，但体积测定的时间有显著性差异。

期刊介绍： Primarily being a medical journal, JPMA publishes scholarly research focusing on the various fields in the areas of health and medical education. It publishes original research describing recent advances in health particularly clinical studies, clinical trials, assessments of pathogens of diagnostic importance, medical genetics and epidemiological studies. Review articles highlighting importance of various issues in the domain of public health, drug research and medical education are also accepted. As a leading journal of South Asia, JPMA remains cognizant of the recent advances in the rapidly growing fields of biomedical sciences, it invites and encourages scholars to write short reviews and invited editorials on the emerging issues. We particularly aim to promote health standards of developing countries by encouraging manuscript submissions on issues affecting the public health and health delivery services.
