Ion Robotic Bronchoscopy-Guided Microwave Ablation Under Augmented Fluoroscopy: An Initial Case Series and Comparative Procedural Workflow Analysis.
Article in Cardiovascular and interventional radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeBronchoscopic microwave ablation (MWA) is an emerging therapy for peripheral pulmonary lesions. Clinical cohorts evaluating the Ion robotic-assisted bronchoscopy (RAB) system for MWA remain lacking. We report our initial prospective experience with Ion RAB-guided MWA using an augmented fluoroscopy (AF) workflow, benchmarked against a historical electromagnetic navigation bronchoscopy (ENB) cohort. MATERIALS AND
methodsThis prospective single-center cohort study evaluated 21 consecutive patients prospectively enrolled to undergo microwave ablation (MWA) for peripheral pulmonary lesions using the Ion RAB system (25 lesions) between January 1, 2025, and January 1, 2026, and benchmarked these outcomes against a retrospectively established historical cohort of 42 consecutive ENB-guided MWA procedures (51 lesions) performed at the same center under an augmented fluoroscopy (AF) strategy. The primary endpoint was postoperative day 1 (POD1) technical success. Secondary endpoints included 6-month treatment success, navigation/total workflow times, cone-beam CT (CBCT) acquisitions, radiation dose, and complications.
resultsPOD1 technical success was 100% (21/21) for RAB and 92.9% (39/42) for ENB (p = 0.545). At 6 months, treatment success was 100% (21/21) vs. 90.5% (38/42), respectively (p = 0.292). Benchmarked against ENB, RAB significantly reduced median navigation time (2 vs 28.5 min, p < 0.001), total workflow time (75 vs 128 min, p < 0.001), and CBCT acquisitions (2 vs 4, p < 0.001). Consequently, median radiation dose was significantly lower for RAB (118 vs 215 mGy, p < 0.001). Complication rates were 4.8% and 7.1%.
conclusionIon RAB-guided MWA under AF is feasible and safe. This RAB workflow ensures precise ablation while offering superior efficiency and substantially reducing patient radiation exposure.
