作者复习了26例原发性肝癌(HCC)或腺癌增生的32个病灶经PEI治疗前后的CT和CTAP表现。2例手术切除标本经组织学检查。以评价HCC或不明确恶性病灶经PEI治疗后病灶周围肝实质的变化。病灶大小在8～66mm之间,多数小于3cm,24个病灶为单独PEI治疗,8例为经肝动脉栓塞治疗后进行PEI治疗。 The authors reviewed CT and CTAP findings before and after PEI treatment in 26 lesions of 26 cases of primary liver cancer (HCC) or adenocarcinoma hyperplasia. Two surgical specimens were examined by histology. To assess the changes of hepatic parenchyma around the lesion after PEI treatment for HCC or indeterminate malignant lesions. The size of the lesions ranged from 8 to 66 mm, most of which were less than 3 cm. 24 lesions were treated with PEI alone, and 8 patients were treated with PEI after hepatic artery embolization.
