Objective: To investigate the value of MR perfusion imaging in evaluating the curative effect of intervention treat-ment 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 time-intension 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 PWI on detection of residuary or recurrent tumor were 0.89 and 0.73 respectively. Conclusion: PWI 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.
