Abstract:
Objective To explore the value of enhanced T2 weighted angiography (ESWAN) in displaying the characteristic of intracranial tumors and estimating the preoperative grading diagnosis of glioma.Methods Totally 68 patients with intracranial mass detected by CT scanning were selected.All patients were conducted with ESWAN scanning and conventional MR scan (T1WI,T2WI,T2-flair) plus T1 enhanced scan by 3.0T magnetic resonance scanner.ESWAN images was compared to conventional MR images,and their differences in displaying tumor morphological characteristics such as border of tumor,peritumoral edema,hemorrhage vascular structure and internal structure were evaluated.The ESWAN sequence was used to evaluate the size and ratio of magnetic sensitive signals in glioma,and the relationship between the magnetic sensitive signal and the benign and malignant glioma was analyzed.Results There was no significant differences among the five sequences in showing the bound of the tumors.Significant differences among the five sequences were founded in displaying peritumoral edema,hemorrhage and vascular structure,internal characteristics.The T2-flair and T2WI showed peritumoral edema well.Enhanced T1WI showed internal characteristics best.ESWAN displayed intra-tumoral hemorrhage and vascular structure best.High grade gliomas had a higher magnetic sensitive ratio than low grade gliomas.Conclusion ESWAN can better show bleeding and vascular structure of intracranial tumor than the routine MR sequence.It can provide important supplementary information for preoperative grading of the cerebral gliomas through assessment of hypointensity ratios in the gliomas.
