Assessment of image quality of a radiotherapy-specific hardware solution for PET/MRI in head and neck cancer patients.

ABSTRACT:

Background and purpose

Functional PET/MRI has great potential to improve radiotherapy planning (RTP). However, data integration requires imaging with radiotherapy-specific patient positioning. Here, we investigated the feasibility and image quality of radiotherapy-customized PET/MRI in head-and-neck cancer (HNC) patients using a dedicated hardware setup.

Material and methods

Ten HNC patients were examined with simultaneous PET/MRI before treatment, with radiotherapy and diagnostic scan setup, respectively. We tested feasibility of radiotherapy-specific patient positioning and compared the image quality between both setups by pairwise image analysis of ¹⁸F-FDG-PET, T1/T2-weighted and diffusion-weighted MRI. For image quality assessment, similarity measures includin
