Abstract:
Objective To observe the value of dual-energy CT bone marrow analysis technology for distinguishing different stages of rib fracture.Methods Totally 273 ribs with fractures in 60 patients who underwent dual-energy CT scanning were retrospectively enrolled and divided into hematoma inflammation stage group(n=166),fibrous callus stage group(n=35)and bony callus-plastic stage group(n=72)according to the stage of rib fracture.The increment 1 and 2 of standardized CT value were calculated based on original CT images and virtual noncalcium color coded maps,respectively,and then were compared among 3 groups and between each 2 groups,and their values for distinguishing different stages of rib fracture were analyzed.Results Significant differences of increment 1 and 2 of standardized CT value were found among 3 groups(both P＜0.05).Increment 1 of standardized CT values were significantly different between fibrous callus stage group and bony callus-plastic stage group(P＜0.05),while increment 2 of standardized CT values were significantly different between each 2 groups(all P＜0.05).Taken 81.575 HU as the cutoff value,the area under the curve(AUC)of increment 1 of standardized CT value for distinguishing fibrous callus stage and bony callus-plastic stage rib fracture was 0.652.Taken 55.700 and 37.625 HU as the cutoff values,AUC of increment 2 of standardized CT value for distinguishing hematoma inflammation stage and fibrous callus stage rib fracture,and fibrous callus stage and bony callus-plastic stage rib fracture was 0.668 and 0.905,respectively.Conclusion Increment of standardized CT value based on dual-energy CT bone marrow analysis technology was helpful for distinguishing different stages of rib fracture,especially fibrous callus stage and bony callus-plastic stage rib fracture.
