Sponsor's own description

Gliomas are the most common primary brain tumor. Gliomas with different grades have different clinical behaviors that determine treatment planning and patient prognosis in clinical practice. In the 2021 World Health Organization (WHO) classification of tumors for the central nervous system, glioma genotyping was considered the most relevant information for neuroradiologists. The isocitrate dehydrogenase (IDH) genotype and 1p/19q codeletion status are two essential molecular markers that divide glioma into three groups: IDH wild-type, IDH mutant with 1p/19q non-codeletion, and IDH mutant with 1p/19q codeletion. MRI contrast clearance analysis (CCA) is based on T1 delayed-contrast subtraction map, Blue/tumor regions in CCA represent efficient clearance of contrast from the tissue (delayed signal\<early signal), while red/nontumor regions in CCA represent contrast accumulation (delayed signal\>early signal). However, there are not any reports on the role of MRI CCA in glioma grading and genotyping, Thus, We hypothesized that the proportion of blue/red region and their histogram analyses, which could be acquired for predicting IDH genotypes and 1p/19q codeletion in gliomas, and to assess the application of CCA in glioma grading.
