Role of PET/MRI in Head and Neck Cancer

PET/CT and PET/MRI Based Treatment Modalities in the Modern Oncology

Study aim was to investigate the diagnostic role of Positron Emission Tomography / Magnetic Resonance Imaging (PET/MRI) in head and neck cancer.

This study was assessed the role of Diffusion weighted imaging (DWI) in discriminating between benign and malignant lesions in Head and neck cancer as well as studying the relationship between glucose metabolism (18F-FDG) and Apparent diffusion coefficient (ADC) for better tumor assessment.

Inclusion Criteria:

• Proved Head and neck cancer
• Underwent PET/CT and PET/MRI
• Lymph nodes due to primary Head and neck cancer.

For healthy subject:

• No previous history of malignancy.
• no inflammation or infection in the neck region.
• lymph node size <10mm.

Exclusion Criteria:

• patients treated before by radiotherapy / chemoradiotherapy
• patients underwent surgery
• artifacts
