【摘要】 目的:比较CT平扫与增强扫描对肝脾肾钝性损伤的诊断能力。方法:回顾性分析临床疑似钝性肝脾肾损伤,并经手术和临床观察证实的CT平扫和增强扫描的患者84例。结果:平扫确定的损伤:肝12例,脾25例,肾5例;平扫可疑损伤:肝22例,脾15例,肾5例。增强确定的损伤:肝32例,脾40例,肾12例(全肾梗塞1例,局限性梗塞3例);对比剂外溢(活动性出血)3例;无可疑损伤。平扫无异常而增强确定有损伤:肝10例,脾5例,肾2例。增强显示的损伤灶比平扫范围明显大、病灶多、界限清楚。结论:CT增强扫描显示肝脾肾损伤明显优于平扫,延时扫描有助于发现活动性出血,应常规增强扫描。更多还原

【Abstract】 Objective:To determine which one between plain and contrast-enhanced CT was better for detecting injuries of liver,spleen and kidney after blunt abdominal trauma.Methods:A retrospective review of plain and contrast-enhanced CT films was performed for 84 patients,whose liver,spleen and kidney were suspected of injuries by the clinical and other examinations.Results:On plain CT,injuries of 12 livers,25 spleens and 5 kidneys were confirmed,and injuries of 22 livers,15 spleens and 5 kidneys were suspected.On contrast-enhanced CT,contrast material extravasation(or active bleeding) 3 case,liver injruy 32 cases,splenic injury 40 cases and renal injury 12 cases(including global infarction of kidney 1 case and local renal infarction 3 cases) were confirmaed.The injury foci found were more,lager,and more distinct on contrast-enhanced CT than plain CT.Conclusion:Contrast-enhanced CT scans is far better than plain CT.Delayed CT scans through the injury foci is helpful to detect active bleeding.Contrast-enhanced CT scans should be a routine examination.更多还原
