Abstract:
Objective To evaluate the diagnostic value of gray scale contrast-enhanced ultrasonography(CEUS) in the diagnosis of active hemorrhage of the kidney.Methods Forty-six active hemorrhage animal models were created within the kidney of 23 New Zealand rabbits heparinized under general anesthesia,rabbit kidneys were examined by routine two dimensional ultrasonography and CEUS.Results Routine ultrasonography showed 26 traumas with irregular and poorly defined margins.CEUS showed all active bleeding sites,contrast agents overflowed from injured blood vessel and formed irregular remarkable enhanced parts.After average 85s for contrast agent was injected,the intensity of the enhanced regions in the kidneys were significantly higher than those of normal renal parenchyma.Conclusions CEUS could clearly demonstrate the active hemorrhage in traumatic kidney and could significantly improve the diagnostic level of ultrasonography.
