This study used 14 of our own patients and a review of the literature in order to determine the value of CT and sonography for investigating injuries to the liver. It appears that CT, with a sensitivity of 0.93, has a somewhat higher accuracy than sonography, which has a sensitivity of 0.83. We were also able to observe typical changes in the appearances, depending on the interval since the injury. Fresh injuries appeared as isodense or mildly hypodense areas, together with variable hyperdense portions on CT. Subsequently these areas become increasingly hypodense and may evolve into cystic lesions. Sonographically, recent injuries of the liver show echo-rich, non-homogeneous lesions which may contain smaller echo-free portions. Older lesions become increasingly devoid of echoes and become increasingly demarcated from normal liver parenchyma.
本研究纳入了我们自己的14例患者，并回顾了文献，以确定CT和超声检查在肝脏损伤检查中的价值。结果显示，CT的敏感性为0.93，其准确性似乎略高于超声检查，后者的敏感性为0.83。我们还能够观察到根据受伤后的时间间隔而出现的典型外观变化。新鲜损伤在CT上表现为等密度或轻度低密度区域，伴有不同程度的高密度部分。随后，这些区域逐渐变为低密度，并可能演变成囊性病变。在超声检查中，肝脏近期损伤表现为回声丰富、不均匀的病变，可能包含较小的无回声部分。陈旧性病变的回声越来越少，并与正常肝实质的界限越来越清晰。
