Procedural CT images were analyzed using a deterministic tract-planning system implemented in 3D Slicer with AI-assisted whole-thorax segmentation (TotalSegmentator) and predefined anatomic and geometric constraints. Literature-reported odds ratios for pneumothorax and pulmonary hemorrhage were encoded as fixed coefficients to characterize procedural burden across feasible trajectories. No model training, outcome-based fitting, or patient-specific adverse-event prediction was performed. Operator-used skin entry sites were identified on procedural CT images and compared with system-derived feasible entry locations under identical geometric assumptions. Concordance was assessed using Euclidean distance and patient-position agreement.</p><p><strong>Results: </strong>Diagnostic samples were obtained in 169 of 199 procedures (84.9%). Any adverse event occurred in 125 procedures (62.8%), including clinically relevant adverse events in 25 (12.6%). The median Euclidean distance between operator-used skin entry sites and the nearest tract among the 10 lowest-burden system-derived trajectories was 15.2 mm (IQR, 6.34-30.85 mm; range, 0.3-181.4 mm). Positioning agreement was moderate (κ = 0.534; 95% CI, 0.432-0.632; p < .001).</p><p><strong>Conclusion: </strong>A deterministic tract-planning framework generated anatomically feasible entry locations spatially concordant with operator-selected skin entry sites. These findings support reproducible visualization of feasible access alternatives within a case-specific decision space for planning review, case review, and operator training.</p>","PeriodicalId":49962,"journal":{"name":"Journal of Vascular and Interventional Radiology","volume":" ","pages":"108944"},"PeriodicalIF":3.1,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148399897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
