Quantification of fractional tumor burden for the early detection of post-treatment glioblastoma progression

Key Points

• The aim is to quantify fractional tumor burden (FTB) for better detection of glioblastoma progression after treatment.
• Utilized MRI for imaging glioblastoma patients.
• Created FTB maps to visualize brain lesion heterogeneity.
• Performed quantitative analysis to differentiate tumor growth from treatment effects.
• Achieved reasonable accuracy in distinguishing between tumor growth and treatment effect.
• Demonstrated that FTB maps are effective in identifying tumor changes over time.
