MRI radiomics analysis of molecular alterations in low-grade gliomas.

International journal of computer assisted radiology and surgery Dec 21, 2017
PURPOSE: Low-grade gliomas (LGG) are classified into three distinct groups based on their IDH1 mutation and 1p/19q codeletion status, each of which is associated with a different clinical expression. The genomic sub-classification of LGG requires tum...
