Meta-Analysis of Teleradiology in Supporting Interventional Radiology: Outcomes, Accuracy, and Workflow Efficiency

Abstract

Background:
Teleradiology has emerged as a transformative tool in interventional radiology (IR), enhancing diagnostic accuracy, workflow efficiency, and patient outcomes. This meta-analysis evaluates the impact of teleradiology on decision-making, procedural success, and healthcare accessibility in IR settings.
Methods:
A systematic review and meta-analysis of ten studies were conducted, assessing diagnostic accuracy, workflow optimization, and clinical outcomes. Effect sizes were calculated using odds ratios (ORs) and 95% confidence intervals (CIs). Publication bias was evaluated using a funnel plot.
Results:
Teleradiology significantly improved diagnostic accuracy (e.g., STRokE DOC trial: OR = 4.2, 95% CI: 1.69–10.46, p = 0.002) and workflow efficiency by reducing interhospital transfers and treatment delays. The DEFUSE 3 trial demonstrated that remote imaging-guided thrombectomy improved procedural success (OR = 2.3, 95% CI: 1.5–3.6, p = 0.01). Clinical outcomes were also favorable, with lower mortality rates observed in teleradiology-supported interventions (Handschu et al.: 1.3% vs. 6.8%). The funnel plot indicated minimal publication bias (Asymmetry Score = 0).
Conclusion:
Teleradiology enhances diagnostic precision, streamlines workflows, and improves patient outcomes in IR. Despite logistical challenges, advancements in AI-driven diagnostics and telecommunication infrastructure will further establish teleradiology as a standard component of modern IR practice.
