摘要
目的探讨腹膜后原发肿瘤及肿瘤样病变的影像学诊断价值。方法对20例经术后病理证实的腹膜后肿瘤的X线、CT、MRI表现特点进行分析。结果 CT及MRI的定位诊断准确率较高,为85%和100%。良恶性肿瘤的大小无明显差异。CT与MRI可显示肿瘤的大小形态与周围组织的关联。结论 CT、MRI定位价值较高,对明确肿瘤的境界和质地,有其重要的诊断价值。
Objective To discuss imaging diagnostic value of retroperitoneal primary tunor and tumor-like lesion.Methods To analyse 20 cases characteristic imagings of X-ray and CT and MRI and uitrasound of retroperitoneal tumor which had been confirmed by pathology after the surgical operation.Results The accurate location rate of CT and MRI is higher,which was 85% and 100%.There was not obvious differential size between benign and malignant tumor.The CT and MRI can display the size,shape of tumors and the relevance of the surrounding tissue of tumors.Conclusion The CT,MRI migth have the higher location value.The CT and MRI could manifest the qualities and boundary of tumors,and could have important diagnostic value.
