目的 :比较正电子发射计算机断层显像 (PET)和 CDFI在实质脏器肿瘤 HIFU疗效判断中的作用。方法 :30例中晚期实质脏器肿瘤经 HIFU治疗后 ,分别行 PET检查和 CDFI前后对照检查 ,其中 8例患者 HIFU后行穿刺活检。结果 :CDFI对照检查结果和 PET检查结果基本一致。结论 :PET和 CDFI均可用来判断实质脏器肿瘤HIFU疗效 ,PET较为准确但费用昂贵 ,CDFI简单易行 ,值得推广。
Objective: To compare the effect of positron emission computed tomography (PET) and CDFI in the evaluation of HIFU efficacy in parenchymal organ tumors. Methods : Thirty patients with advanced parenchymal organ tumors were treated with HIFU after PET and CDFI before and after the follow-up. Among them, 8 patients were followed by needle biopsy after HIFU. RESULTS : The CDFI control test results were basically consistent with the PET test results. Conclusion : Both PET and CDFI can be used to judge the efficacy of HIFU in parenchymal organ tumors. PET is more accurate but expensive. CDFI is simple and easy to use and worthy of promotion.
