目的 :探讨超声 (US)与CT对肝脓肿的诊断及介入治疗的价值。方法 :先行US检查后再作CT扫描 ,两者最短间隔 30min ,最长 2 4h ;4例仅作了平扫 ,13例作了平扫及增强扫描 ,其中 9例采用动态扫描。结果 :14例经US或CT导引下穿刺抽吸及细菌学证实肝脓肿 ,3例经临床大剂量抗生素治疗、US与CT随访证实肝脓肿 ;US确诊 10例 ,疑诊 2例 ,漏误诊 5例 ;CT确诊 14例 ,疑诊 1例 ,误诊 2例。结论 :US与CT对肝脓肿的诊断均很敏感且价值很高 ,对不典型肝脓肿诊断CT价值优于US。
Objective: To investigate the value of ultrasonography (US) and CT in the diagnosis and interventional treatment of hepatic abscess. Methods: CT scan was performed before the US examination. The shortest interval between the two was 30 minutes and the maximum was 24 hours. Only 4 cases underwent plain scan and 13 cases underwent plain and enhanced scanning. Among them, 9 cases underwent dynamic scanning. Results: Fourteen cases of liver abscess were confirmed by aspiration or bacteriological examination under the guidance of US or CT. Three cases were treated with high-dose antibiotics. US and CT were followed up to confirm liver abscess. US was diagnosed in 10 cases, suspicious in 2 cases, misdiagnosis 5 cases; 14 cases were diagnosed by CT, 1 case was suspected and 2 cases were misdiagnosed. Conclusion: Both US and CT are sensitive and valuable in the diagnosis of liver abscess. The diagnostic value of CT in diagnosing atypical liver abscess is better than that of US.
