Diagnostic Performance of the Ultra Low-Dose (ULD) Scanner vs. Diagnostic Performance With Standard X-rays in the Emergency Department Compared With Performance of the Standard Classical-dose Scanner for Trauma of the Dorsolumbar Spine, Pelvis and Extremities (ULD-Traumato)
Study Overview
Status
Conditions
Detailed Description
The main purpose of this study is to compare the diagnostic performances of the ULD scanner with those of the standard X-ray when looking for fractures of the dorsolumbar region, the pelvis, proximal femur or the extremities, in an emergency situation in adults, once the diagnosis of fracture has been ascertained by the classical standard-dose scanner (gold standard). The statistical analyses will be performed with the help version 9.4 or subsequent versions of SAS software (SAS Institute, Cary, NC, USA) and/or version 3.5.1 or subsequent versions of R software (R Development Core Team (2018). R Foundation for Statistical Computing, Vienna, Austria).
The secondary objectives of this study are to:
A. Compare the diagnostic performances of the two examination methods under study (ULD scan vs. standard X-ray) in the search for bone structure anomalies, damage to the soft tissues, damage to the joints and/or discopathies at the site(s) involved.
B. Compare the diagnostic performances of the two examination methods under study) (ULD scan vs. standard X-ray) in the search for fractures of the site involved. C. Evaluate the diagnostic agreement between two readers (senior radiologist and junior radiologist) for each of the two examination methods under study (ULD scan vs. standard X-ray).
D. Compare the radiologist's self-declared impression of each of the two examination methods under study (ULD scan vs. standard X-ray) in terms of subjective quality: overall image quality, diagnostic quality of the examination method and the level of confidence in the diagnosis made, overall and for each of the two readers (senior and junior).
E. Compare the doses of X-rays administered for each of the two examination methods under study (ULD scan vs. standard X-ray).
F. Compare the interpretation time for each examination method under study (ULD scan vs. standard X-ray), globally and for each of the two readers (senior and junior).
For the evaluation of the diagnostic performances (main objective and secondary objectives A et B), only the senior radiologist's interpretation will be considered.

Image quality of the ULD scanner and standard X-ray
Time Frame: Day 0
|
By means of a 4-point Likert scale, both the senior and junior radiologists can give their subjective impression of the overall image quality of each of the two examination methods under study (ULD scan vs. standard X-ray) by saying how much they agree or disagree that the overall quality of the image is good enough to detect a fracture.
On the Lickert scale, 1- Uninterpretable, 2- Interpretable in spite of a slight technical problem (centering, movement, constant), 3-Completely interpretable in spite of a slight technical problem.
4- No technical problem.
