简要总结
Low grade gliomas (LGGs) are malignant, infiltrative and incurable brain tumours that typically present in the younger population. This project proposes to use non-contrast metabolic "Saturation Transfer" (ST)-MRI to evaluate LGG tumour progression and aims to predict early changes in LGG. Early identification of LGG patients whose tumours will progress will permit early interventions. ST-MRI does not involve any intravenous injection of contrast and which acquires metabolic information not seen by standard MRI.

研究组 & 干预措施
ST-MRI scans
All patients will undergo Saturation Transfer (ST)-MRI during their standard of care imaging visits (or within 14 days of their standard MRI).
干预措施: Saturation Transfer (ST)-MRI (Diagnostic Test)
结局指标
主要结局
The time-to-progression as measured by Saturation Transfer (ST)-MRI (based on a change in volume or parameter value of over 10%) relative to the time-to-progression as measured by standard MRI using RANO-LGG.
时间窗: Up to 6 years, from date of initial (ST)-MRI scan until the date of progression
Time-to-progression refers to clinical progression of a low-grade glioma to a higher tumour grade.
次要结局
- Accuracy of Saturation Transfer (ST)-MRI for detecting progression (based on a change in volume or parameter value of over 10%).(Up to 6 years, from date of initial (ST)-MRI scan until the date of progression)
