In plain language
In 45 patients undergoing liver and prostate embolization at one German center, robotic catheter navigation from the control room was feasible in about 89% of cases and the remote operator recorded no measurable dose; in-room staff dose was not measured.

What it found
Operator dose was lower with remote robotic operation from the control room than with conventional manual procedures.
Key figures: 0.000 mSv (IQR 0.000) vs. 0.005 mSv (IQR 0.005); p < .001
Robotic visceral interventions were technically successful in most cases, with two conversions to manual navigation.
Key figures: 16/18 (88.9%; 95%-confidence interval (CI) (Wilson) 67.3-96.7%)
Patient procedural dose did not differ significantly between robotic and conventional procedures.
Key figures: 107.85 Gycm2 vs. 128.00 Gycm2; p = .286
Procedure duration and total examination time were similar, attributed to parallel preparation of the robot.
Key figures: 65 vs. 59 min, p = 0.711; 100 vs. 100 min, p = 0.853
Robotic procedures were performed remotely by a pregnant interventionalist without lead gear; staff in-room dose was not formally assessed.
Limits to keep in mind
Small, single-center, non-randomized pilot with different operators and suites for each arm; only operator dose was measured, not in-room staff dose, and manual access steps still required in-room staff.
