Abstract:

Objective

To analyze the clinical value of three-dimensional arterial spin labeling(3D-ASL)combined with dynamic contrast enhanced magnetic resonance imaging(DCE-MRI)in the diagnosis of recurrence of glioma and radiation brain necrosis.

Methods

Retrospective study was conducted on the clinical data of 60 patients with glioma who received postoperative adjuvant radiotherapy in Zhuozhou City Hospital from January 2019 to December 2021.The new abnormal enhancement lesions were found by routine MRI examination, and they were divided into postoperative recurrence group of glioma(n=38)and radiation brain necrosis group(n=22)after confirmed by secondary surgical pathology.The patients in both groups received MRI, 3D-ASL and DCE-MRI to obtain the quantitative parameters of 3D-ASL and DCE-MRI.The parameters of the two groups were compared and the clinical value of 3D-ASL combined with DCE-MRI in the diagnosis of postoperative recurrence and radiation brain necrosis of glioma was analyzed.

Results

The rCBF and Ktrans values of glioma recurrence group were higher than those of radiation brain necrosis group(P<0.05). The accuracy of 3D-ASL combined with DCE-MRI was higher than that of single examination(P<0.05). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of 3D-ASL combined with DCE-MRI were higher than those of single examination(P<0.05).

Conclusion

3D-ASL combined with DCE-MRI can be used clinically to distinguish the recurrence of brain glioma from radiation brain necrosis.The combined examination of the two has extremely high diagnostic value and can improve the diagnostic accuracy.
