Optimized Diffusion-Weighted Imaging for the Evaluation of Post-Treatment Squamous Cell Carcinoma in the Neck: Comparative Study With FDG PET/CT

The investigators propose a longitudinal study evaluating post-treatment changes in patients with squamous cell carcinoma (SCC) of the neck using an innovative optimized diffusion-weighted imaging (DWI) pulse sequence to identify more accurately recurrent tumors as well as early non-responders to therapy.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: DWI MRI; -The patients will undergo an optimized research neck DWI MRI, up to 3 weeks post-treatment and then a standard-of-care 3-month post-treatment FDG PET/CT examination.	Device: Diffusion-weighted imaging magnetic resonance imaging; The research MRI study of the head and neck will be performed on a Siemens 3T MRI Scanner system; Other Names: DWI MRI

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Apparent diffusion coefficient mean (ADCmean)	ADC=measure of the magnitude of diffusion (of water molecules) within tissue; The primary tumor, suspicious lesion, and/or area of post-treatment change will be identified in anatomical images & then outlined in the ADC sequence, excluding areas of cystic change and necrosis. If there are multiple lesions, only the dominant lesion with the lowest ADC will be used for analysis; A histogram analysis method will examine the distribution of ADC values within each region of interest (ROI); ADCmean will describe distribution of ADC measurements in tumor/non-tumor tissues & independent sample t-test will compare ADC measurements between the 2 groups	2-3 weeks post-standard of care treatment
Apparent diffusion coefficient lowest value in a tumor (ADCmin)	ADC=measure of the magnitude of diffusion (of water molecules) within tissue; The primary tumor, suspicious lesion, and/or area of post-treatment change will be identified in anatomical images & then outlined in the ADC sequence, excluding areas of cystic change and necrosis. If there are multiple lesions, only the dominant lesion with the lowest ADC will be used for analysis; A histogram analysis method will examine the distribution of ADC values within each region of interest (ROI); ADCmin will describe distribution of ADC measurements in tumor/non-tumor tissues & independent sample t-test will compare ADC measurements between the 2 groups	2-3 weeks post-standard of care treatment

Secondary Outcome Measures

Outcome Measure	Time Frame
Number of non-responders to treatment as measured by DWI MRI as compared to the number of non-responders to treatment as measured by FDG PET/CT	2-3 weeks post-standard of care treatment
