【摘要】 目的:探讨肝癌射频消融(radiofrequency ablation,RFA)手术前后,对比增强计算机体层摄影术(contrast-enhanced computed tomography,CECT)和对比增强超声检查(contrast-enhanced ultrasonography,CEUS)在判断肿瘤病灶中的应用价值。方法:对2008年5月-2010年9月接受RFA的90例肝癌患者(原发性肝癌65例,转移性肝癌25例)的临床资料进行回顾性分析。共104个肝内肿瘤病灶在B超或CT引导下行RFA。RFA术前1周及术后1个月行CECT和CEUS,评价CECT和CEUS在术前肿瘤病灶检出及术后疗效评价中的作用。结果:RFA治疗前,CECT共检出93个肝内肿瘤病灶,CEUS共检出96个肝内肿瘤病灶,CECT结合CEUS共检出104个肝内肿瘤病灶。RFA治疗后1个月,CECT显示90个病灶无增强表现,CEUS显示91个病灶无增强表现,CECT结合CEUS显示86个病灶无增强表现;CECT检出5个肝内新发肿瘤病灶,CEUS检出8个肝内新发肿瘤病灶,CECT结合CEUS检出11个肝内新发肿瘤病灶。结论:CECT结合CEUS可提高RFA治疗前肝内肿瘤病灶检出率及RFA治疗后肝内残留肿瘤和新发肿瘤病灶的检出率。更多还原

【Abstract】 Objective:To investigate the values of CECT(contrast-enhanced computed tomogramphy) and CEUS(contrast-enhanced ultrasonography) in the diagnosis of cancerous lesions in the liver before and after RFA(radiofrequency ablation) for liver cancer.Methods:The clinical records of 90 patients with liver cancer(65 primary liver cancer and 25 metastatic liver cancer) undergoing RFA between May 2008 and September 2010 were retrospectively analyzed.A total of 104 cancerous lesions in the liver were treated with CT-or ultrasound-guided RFA.Each patient underwent CEUS and CECT one week before RFA and one month after RFA.The diagnostic abilities of CEUS and CECT before RFA and the values of CEUS and CECT in the evaluation of therapeutic effect of RFA were assessed.Results:Before RFA,93 and 96 cancerous lesions in the liver were detected by CECT and CEUS,respectively.However,CECT combined with CEUS found 104 lesions.One month after RFA,90 lesions showed no enhancement on CECT,and 91 lesions showed no enhancement on CEUS.CECT combined with CEUS found that 86 lesions showed no enhancement.CECT,CEUS and the CECT combined with CEUS found 5,8 and 11 recurrent lesions in the liver,respectively.Conclusion:CECT combined with CEUS can increase the detection rates of cancerous lesions in the liver before RFA and the residual lesions and recurrent lesions after RFA.更多还原
