Overview
Brief Summary
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.
Investigators
Eligibility Criteria

- •At least 18 years of age
- •Patient must be able to understand and willing to sign a written informed consent document.
Exclusion Criteria

- •Pregnant and/or breastfeeding, with women of childbearing potential having a negative urine or serum pregnancy test
Outcomes
Primary Outcomes
Apparent Diffusion Coefficient Mean (ADCmean)
Time Frame: 2-3 weeks post-standard of care treatment
* 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
Apparent Diffusion Coefficient Lowest Value in a Tumor (ADCmin)
Time Frame: 2-3 weeks post-standard of care treatment
* 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
Secondary Outcomes
- Number of Participants That Were Non-responders to Treatment on Both the DWI MRI and the Standard of Care FDG PET/CT(2-3 weeks post-standard of care treatment)
