Summary

Glioma is the most common primary intracranial tumor in adults, with high-grade gliomas accounting for more than 50% of all gliomas and having the highest mortality rate. The molecular characteristics of gliomas are closely associated with the selection of treatment regimens, therapeutic efficacy, and patient prognosis. Mutations in isocitrate dehydrogenase (IDH) are an important diagnostic marker for diffuse gliomas and a key component in distinguishing and defining glioma subtypes. Furthermore, the advent of IDH-targeting inhibitors has brought hope to patients with IDH-mutant gliomas. Therefore, accurately assessing the IDH mutation status of gliomas is a prerequisite and key to precision diagnosis, targeted therapy, and prognostic evaluation. This study explores the application value of targeted IDH PET/MRI imaging in glioma subtype diagnosis, tumor grading, and prognostic evaluation. It aims to establish a non-invasive in vivo tracing technology platform and evaluation system for accurately assessing glioma IDH mutation status, subtype diagnosis, and prognostic evaluation. This will provide a basis for the precise diagnosis of gliomas, the selection of targeted treatment regimens, and prognostic assessment, and promote future research and development of therapeutic drugs using labeled therapeutic radionuclides.

Detailed description

1. Clinical and biological data: The records include all patients' general clinical information, disease course, and other imaging findings. 2. PET image analysis: Record and assess lesion location, size, maximum standardized uptake (SUVmax), and target-to-species ratio (TBR), where the TBR value is calculated by dividing the SUVmax of the lesion by the background SUVmean. 3. Pathological analysis: Hematoxylin and eosin staining and immunohistochemical analyses will be performed. Immunohistochemical analysis will be used to investigate the status of isocitrate dehydrogenase (IDH).
