In brief
Retrospective study of 151 pediatric CLM cases demonstrates that semi-automated MSCT volumetric measurements—particularly lesion volume and lesion-to-lobe ratios—correlate with surgical approach selection. Larger lesions and higher proportional volumes predict lobectomy over lung-sparing procedures, suggesting quantitative imaging may guide preoperative planning.

Abstract
Purpose
To examine the association between the MSCT quantitative measurements of congenital lung malformations (CLM) and the selection of surgical approaches (lobectomy vs. lung-sparing surgery).
Methods
This retrospective study evaluated CLM surgical cases at our institution from 2016 to 2018. MSCT quantitative measurements were generated by a semi-automated approach: the volume of the lesion (Vlesion), the volume of the lesion-involved lobe (Vlobe), the volume of the lesion-involved lung (Vlung) and the volume of the total lung (Vtotal lung). The proportions of Vlesion to Vlobe (Plesion/lobe), Vlesion to Vlung (Plesion/lung), and Vlesion to V total lung (Plesion/total lung) were calculated. We used Logistics regression to examine whether quantitative measurements were associated with the selection of surgical approaches.
Results
151 patients were included (median age at surgery 6 months). 82 patients underwent lung-sparing surgery, and 69 patients underwent lobectomy. Vlesion (OR 1.51, 95% CI 1.09–2.07), Plesion/lobe (OR 1.78, 95% CI 1.16–2.72), Plesion/lung (OR 1.63, 95% CI 1.13–2.35), and Plesion/total lung (OR 1.58, 95% CI 1.12–2.22) were positively associated with the selection of lobectomy.
Conclusion
The application of quantified MSCT analysis may provide insight into the quantitative characteristics of CLM, which could be potentially useful for surgical approach selection.
