Diagnostic Accuracy of PET/CT and Diffusion-weighted MRI in Detecting Residual Oropharyngeal Carcinoma after Chemoradiotherapy

Key Points

• Evaluate the diagnostic accuracy of PET/CT and diffusion-weighted MRI for detecting residual oropharyngeal carcinoma post-chemoradiotherapy.
• Assess sensitivity and specificity of PET/CT and diffusion-weighted MRI
• Focus on local-regional residual disease detection
• Evaluate in the context of oropharyngeal squamous cell carcinoma
• Both imaging techniques demonstrated 100% sensitivity.
• Diffusion-weighted MRI exhibited higher specificity compared to PET/CT.
