Additional file 2 of Definitive-intent uniform megavoltage fractioned radiotherapy protocol for presumed canine intracranial gliomas: retrospective analysis of survival and prognostic factors in 38 cases (2013–2019)

Additional file 2: Figure a. Right frontal glioma. A, B: Pre-treatment T2-WI (A), T1-WI + (B). C,D: Two months post-RT. T2-WI (C), T1-WI + (D). These images show complete response with disappearance of contrast-enhancement. Figure b. Right piriform glioma. A,B: Pre-treatment T2-WI (A), T1-WI+ (B). Absence of contrast enhancement. C,D: 2 months post-RT. T2-WI (C), T1-WI+ (D). These images show PR/SD with decreased T2-WI hyperintensity, according to RECIST criteria for non-enhancing tumour. Figure c: Left piriform glioma. A,B: Pre-treatment T2-WI (A), T1-WI+ (B). C,D: Four months post-RT. T2-WI (C), T1-WI + (D). These images show partial response with persistent diffuse contrast enhancement (dotted arrow).
