DLP, dose-length product; NB: Changed, changed to conventional freehand technique; PD, path deviation; TD, tip deviation; Time, total ‘door-to-door’ procedure time; US, ultrasound; mAS, total milliamp seconds.
Robotic procedures that were fully converted to freehand placement are in italics, with results in parentheses not contributing to calculation of medians.
