Glioma is the most common primary cerebral tumor. Accurate glioma grading is crucial for treatment planning and prognosis. Regular medical examination technology such as histopathologic assessment or Conventional MR imaging examination has their limitations. In this research, we used the T1ρ examination at 3.0T to explore the correlation of the T1ρ value with pathological grades of glioma in 29 patients. Our results suggested that the T1ρ values are negatively correlated with the grade of gliomas.In conclusion, the T1ρ values could potentially serve as non-invasive predictors for the preoperative grading of gliomas.
