Value of MR perfusion imaging after intervention treatment of hepatic cancer

目的将在评估肝的癌症的干预治疗的药品效果调查先生灌注成像的价值。36 个病人在干预治疗以后经历了先生灌注成像的方法。量子化结果在癌残余和良性的组织之间被不同。并且诊断精确性被判定。在那里的结果是在在在外科和良性的改进区域以后的残余肿瘤之间的吝啬的 MSI 的有效差量。残余肿瘤的时间目的曲线被观察很快上升到达山峰，而改进织物的慢慢地上升了到达山峰。察觉上的 PWI 的敏感和特性剩余或再发性瘤分别地是 0.89 和 0.73。结论 PWI 是能被用来在外科以后区分肝织物状况的一种很敏感的成像技术。早贡献的 PWI 上演诊断和动态监视后面的 HCC 外科。

Objective： To investigate the value of MR perfusion imaging in evaluating the curative effect of intervention treatment of hepatic cancer. Methods： 36 patients underwent MR perfusion imaging after intervention treatment. The quantization results were differed between carcinoma residue and benign tissue. And the diagnosis accuracy was judged, Results： There was a significant difference in mean MSI between residue tumor after surgery and the benign enhancement area. The timeintension curve of residue tumor was observed to ascend rapidly to reach the peak, whereas that of the enhancement tissue ascended slowly to reach the peak. The sensitivity and specificity of PWl on detection of residuary or recurrent tumor were 0.89 and 0.73 respectively. Conclusion： PWl is a very sensitive imaging technique that can be used to distinguish liver tissue condition after surgery. PWI contributed to early stage diagnosis and dynamic monitoring following HCC surgery.
