Background: The research was performed to check examination time and artifact vulnerability of whole-body computed tomographies (wbCTs) for trauma sufferers utilizing standard or optimized affected person positioning.
Sufferers and strategies: Examination time was measured in 100 sufferers scanned with standard protocol (Group A: arms positioned alongside the physique for head and neck imaging and over the top for trunk imaging) and 100 sufferers scanned with optimized protocol (Group B: arms flexed on a chest pillow with out repositioning). Moreover, affect of two completely different scanning protocols on picture high quality in probably the most related physique areas was assessed by two blinded readers.
Outcomes: Whole wbCT length was about 35% or three:46 min shorter in B than in A. Artifacts in aorta (27 vs 6%), liver (40 vs eight%) and spleen (27 vs 5%) occurred considerably extra typically in B than in A. No incident of non-diagnostic picture high quality was reported, and no important variations for lungs and backbone had been discovered.
Conclusion: An optimized wbCT positioning protocol for trauma sufferers permits a major discount of examination time whereas nonetheless sustaining diagnostic picture high quality.
