摘要
目的分析肝脓肿诊断中128层螺旋CT的应用价值。方法方便选取2015年1月-2018年12月来该院诊治的73例肝脓肿患者为研究对象,对其128层螺旋CT表现行回顾性分析,对脓肿数目、形态、部位以及增强之后的CT表现进行重点观察,同时与临床资料进行充分结合,对其加强分析。结果①73例肝脓肿患者中,45例为单发,构成比为61.64%,28例为多发,构成比为38.36%;73例肝脓肿患者共检出病灶126个。②经CT平扫之后,可观察到126个病灶均呈现为不均匀或者均匀状态,出现在低于正常肝实质的区域,呈现为不规则形的病灶共有6个,呈现为花瓣状或者多房状的病灶共有20个,呈现为椭圆形或者圆形的病灶共有6个;呈现为等密度的病灶共有6个,呈现为低密度的病灶共有120个;边缘不清楚的病灶共有114个,边缘清楚的病灶共有12个。③增强扫描显示动脉期:肝内低密度病灶周围的肝组织出现明显强化现象,病灶中心主要呈现为低密度,有轻度或者极轻多环状、环状强化现象伴随出现,病灶本身及其周围并未明显强化;静脉期有45例患者出现环靶征,呈现为双环、单环的患者分别有21例、24例;18例呈现为花瓣征;延迟期共有12例患者出现"肿块缩小征"。结论肝脓肿诊断中128层螺旋CT的应用价值理想。
Objective To analyze the application value of 128-slice spiral CT in the diagnosis of hepatic abscess. Methods Convenient selected a total of 73 patients with hepatic abscess who were admitted to the hospital from January 2015 to December 2018 were enrolled in the study. The 128-slice spiral CT findings were retrospectively analyzed. The number, morphology, location, and CT appearance of the abscess were retrospectively analyzed. Focus on observation, and fully integrate with clinical data to strengthen the analysis. Results 1. Of the 73 patients with hepatic abscess, 45 case were single-shot,with a composition ratio of 61.64%, 28 case with multiple doses, and a composition ratio of 38.36%. A total of 126 lesions were detected in 73 patients with hepatic abscess. 2.After CT scan, 126 lesions were observed to be uneven or uniform, appearing in areas below normal liver parenchyma, and there were 6 lesions with irregular shape, showing petal or multi-room.There were 20 lesions in total, and there were 6 lesions with oval or round shape. There were 6 lesions with equal density,120 lesions with low density, and 114 lesions with unclear margins. There are 12 clear lesions. 3.Enhanced scanning showed arterial phase: the liver tissue around the low-density lesions in the liver showed obvious enhancement. The center of the lesion mainly showed low density, with mild or extremely light multi-ring, ring-enhanced phenomenon accompanied by the lesion itself and there were no obvious enhancements around the circumference;there were 45 patients with ring target in the venous phase, 21 patients and 24 patients in the double-ring and single-ring, respectively;18 patients presented with petal signs;12 patients in the delayed phase showed "tumor reduction sign". Conclusion The application value of128-slice spiral CT in the diagnosis of hepatic abscess is ideal.
