Interest in Using Ultrasound Fusion in Percutaneous Interventional Radiology

University Hospital, Strasbourg, France25 enrolled

Overview

The investigators want to evaluate the accuracy of an ultrasound fusion guiding system in the positioning of a needle (here the accuracy is evaluated with a 22G spinal needle), by comparing the path indicated by the ultrasound fusion (virtual line) and the path actually obtained on the control CT scan (real line). Compared with ultrasound guidance alone or CT scan alone, the results are expected to be more accurate, saving time and irradiation (not evaluated here).

Outcomes

Primary Outcomes

Measure of the averages (m) errors of the coordinates in the three planes of space, between the virtual and the real line of the spinal needle (comparison of ultrasound fusion data with control CT scan data achieved once the spinal needle is placed)

Time frame: time of the procedure

Secondary Outcomes

distance between the center of the target and the extension of the spinal needle (perpendicular line to this projection through the center of the lesion)

Time frame: time of the procedure

overall satisfaction score

Time frame: time of the procedure
