Image-guided microwave thermoablation of hepatic tumours using novel robotic guidance: an early experience

Objective To evaluate and compare novel robotic guidance and manual approaches based on procedural accuracy, procedural time, procedural performance, image quality as well as patient dose during image-guided microwave thermoablation. Method The study was prospectively performed between June 2013 and...

Description
Summary:Objective To evaluate and compare novel robotic guidance and manual approaches based on procedural accuracy, procedural time, procedural performance, image quality as well as patient dose during image-guided microwave thermoablation. Method The study was prospectively performed between June 2013 and December 2013 using 70 patients. Forty randomly selected patients (group 1) were treated with manual guidance and 30 patients (group 2) were treated using a novel robotic guidance. Parameters evaluated were procedural accuracy, total procedural time, procedural performance, quantitative/qualitative image quality and patient dose. Two-sided Student’s t test and Wilcoxon rank-sum test were used to test the significance of the data and p values less than 0.05 were considered statistically significant. Result Accuracy parameters were significantly higher in group 2 (all p   group 1; p  = 0.0008). Volume CT dose index and dose–length product were significantly lower for group 2 compared to group 1 (all p
