Abstract

PURPOSE
To measure the magnetization transfer ratio(MTR) of intracranial tumors and to evaluate the difference of the character and the border of tumors on magnetization transfer image.
MATERIALS AND METHODS
We prospectively reviewed magnetization transfer imaging(MTI) findings of intracranial tumors of 13 patients. 1.0T MRI machine was used. T1 weighted image(TRITE=700/14) and T1 weighted magnetization transfer image were obtained. The offset and bandwidth of magnetization transfer pulse were 1000 Hz and 250Hz, respectively. Postcontrast images were also obtained. MTR was measured at lesion area.
RESULTS
The mean of normal MTR of white matter and gray matter in 7 normal volunteers were 37% and 29%, respectively. The MTR of each tumor was as follows;metastatic tumors(mean 16.3%), meningioma(mean 27.3%), oligodendroglioma(mean 20.2%), glomus jugulare tumor(mean 17.3%), gliomatosis cerebri(mean 27. 0%). The contrast of lesions were better at magnetization transfer image than at T1 weighted image.
CONCLUSION
The MTR of the intracranial tumors is lower than normal tissue. Measurement of MTR at muirpie areas within the tumor can be useful for evaluation of indistinct border of the tumor.
