【摘要】 目的 探讨MDCT在诊断、鉴别诊断肝小静脉闭塞病(HVOD)及评价其临床疗效中的的价值。方法 对10例HVOD住院患者行MDCT肝脏三期扫描,在工作站中对原始数据进行多平面重组(MPR)及肝脏血管成像,分析HVOD在MDCT上的表现。10例MDCT诊断为HVOD患者中,1例肝穿证实,9例结合临床和MDCT表现得出诊断结果。结果 10例患者均有不同程度的胸腹水、胆囊壁增厚、肝大但尾状叶大小形态正常;肝静脉均未显影而门静脉通畅;肝实质强化不均匀,门静脉期呈“地图样”强化;6例门静脉周围水肿;下腔静脉各段显示通畅。结论 MDCT结合MPR和血管成像在诊断和鉴别诊断HVOD及评价其临床疗效中有较高价值。更多还原

【Abstract】 Objective To evaluate the value of MDCT in diagnosis and evaluation of the clinical therapeutic effect of hepatic venoocclusive disease(HVOD).Methods Ten patients with HVOD were scanned with MDCT(including three phases).The data were processed using multi-plane reformation(MPR) and liver CT angiography(CTA)at workstation.Of the ten patients,one was diagnosed with HVOD by liver biopsy,while the other nine patients were diagnosed by clinical examinations and combined with imaging findings.Imaging findings of HVOD were analysed.Results MDCT showed that all patients had ascites and hydrothorax,gallbladder walls thickened,hepatomegaly except the caudate lobe,hepatic veins(HV)obstructed but portal veins(PV) and inferior vena cava(IVC) not.Edema surrounding the portal veins was shown in six patients.Conclusion MDCT,especially,MPR and liver CTA can be helpful in diagnosing HVOD and evaluate the clinical therapeutic effect.更多还原
