Baseline fluorodeoxyglucose PET/computed tomography volumetric parameters predict response to transarterial radioembolization in primary and metastatic liver tumors

Key Points

• To evaluate how baseline volumetric metabolic parameters predict treatment response to transarterial radioembolization in liver tumors.
• Assessed baseline volumetric metabolic parameters using PET/CT scans.
• Focused on parameters like MTV and TLG.
• Compared the predictive value in primary versus metastatic liver tumors.
• MTV and TLG showed significant association with treatment response.
• Stronger predictive value observed in primary liver tumors compared to metastatic tumors.
