目的 探讨慢性乙型肝炎(简称慢乙肝)CT征象与肝炎严重程度之间的相关性,评价CT检查在慢乙肝中的应用价值。 方法 收集慢乙肝120例,其中慢乙肝轻度34例,中度22例,重度26例,重型肝炎38例。全部病例均经标准化的螺旋C T增强双期扫描,观察肝脏、胆囊、脾脏、淋巴结、胸腹腔改变。将慢乙肝CT征象与临床及实验室指标作相关分析。 结果 不同分度慢乙肝CT表现之间有一定差异。随着肝炎严重程度的加重,血清白蛋白水平逐渐降低,血清丙氨酸氨基转移酶水平逐渐升高,肝脏内血管周围“晕环征”、胆囊窝水肿、腹腔淋巴结肿大增多、腹腔积液和继发胸部改变的发生率也逐渐升高,两者存在相关性。 结论 肝脏内血管周围“晕环征”、胆道改变、腹腔淋巴结肿大、腹腔积液和继发胸部改变等C T征象可在一定程度上反映慢乙肝的严重程度。螺旋CT检查对于评价慢乙肝严重程度有重要的参考价值。
Objective To investigate the correlation between the CT signs of chronic hepatitis B (CHB) and the severity of hepatitis and evaluate the value of CT in the diagnosis of chronic hepatitis B. Methods 120 cases of chronic hepatitis B were collected, including 34 mild chronic hepatitis B patients, 22 moderate patients, 26 severe patients and 38 severe hepatitis patients. All cases were enhanced by double helical CT scanning with normalized spiral CT, and the liver, gallbladder, spleen, lymph nodes and thoracic and abdominal cavity were observed. CT signs of chronic hepatitis B and clinical and laboratory indicators for related analysis. The results of different degrees of chronic hepatitis B CT showed some differences. With the aggravation of hepatitis, serum albumin levels gradually decreased, serum alanine aminotransferase levels gradually increased, around the blood vessels around the liver “halo sign”, gall bladder edema, abdominal lymph node enlargement, abdominal cavity The incidence of effusion and secondary thoracic changes also gradually increased, the two are related. Conclusions The signs of C T, such as “halo sign”, biliary changes, abdominal lymph nodes, peritoneal effusion and secondary thoracic changes, may reflect the severity of chronic hepatitis B to a certain extent. Spiral CT examination for the evaluation of the severity of chronic hepatitis B has important reference value.
