Abstract:
Objective:The purpose of this study is to locate and characterize splenic trauma with contrast-enhanced ultrasound(CEUS).Methods:A defined mild intraparenchymal lesion was done in 2 pigs.Ultrasound features after trauma were observed by baseline ultrasound,color Doppler flow images(CDFI) and CEUS with a contrast agent(Sono Vue),respectively.Results:In 2 pigs,focal intraparenchymal lesions on spleen with diameters ranging from 10.0 to 10.0 mm could be identified by CDFI and CEUS but not by the baseline ultrasound.Hyperechoic rift in spleen was visible along trauma area as enhancement in splenic parenchyma disappeared on CEUS.Hyperechoic line could be kept in a long time.The hyperechoic rift also appeared at the sub-capsular region beside a traumatic lesion.Hyperechoic rift in traumatic region could be seen even as CEUS was converted to conventional B-mode.Enhancement in the traumatic lesion was clearly seen in CDFI.Conclusion:Hyperechoic rift in spleen was visible along trauma area as a contrast agent is used.CEUS is useful in identifying the grade,range and location of splenic injury.
