Fig. 1From: Cell-free DNA and circulating TERT promoter mutation for disease monitoring in newly-diagnosed glioblastomaCorrelations between cell-free DNA concentration at baseline and MRI characteristics. The cfDNA concentration is plotted against three tumor volumes: a T2-Flair; b T1-enhanced volume with necrosis; c T1 enhanced volume without necrosis (p = 0.018); and d rCBV (p = 0.03). rCBV had the highest association with cfDNA concentration. Gado: gadolinium; W/: with; W/O: without; rCBV: relative cerebral blood volumeBack to article page
