Moderator: Dr Angela Waweru

Speakers & Topics:

• Dr Harish Nagaraj: Radiologic Imaging of Head & Neck Cancers
• Dr Solomon Mutua: Role of PET/CT Scan in Head & Neck Imaging

Dr. Solomon Mutua emphasized the value of PET/CT in radiotherapy planning:
– PET/CT allows for biologic imaging of tumors, identifying hypoxic and metabolically active subvolumes.
– Integration improves accuracy in delineating gross tumor volume (GTV), allowing for dose escalation while minimizing toxicity.
– Particularly beneficial in cases with occult primaries, equivocal CT/MRI, and in adaptive RT strategies.
– PET/CT-based contouring can reduce geographical misses and optimize nodal staging and treatment response.
– Hypoxia imaging and dose painting are under investigation to further personalize radiotherapy protocols.
