Brief Summary
This clinical trial studies diffusion-weighted magnetic resonance imaging (MRI) in identifying and localizing tumors in patients with non-small cell lung cancer undergoing radiation therapy. Diagnostic procedures such as diffusion weighted MRI may help identify where active cancer is to improve the targeting accuracy of radiotherapy. Comparing results of diagnostic procedures done before, during, and after radiation therapy may help determine how the location and volume of tumors changes over time and predict how the tumor will respond to therapy.

Outcome Measures
Primary Outcomes (4)
Measurement of gross tumor volume and involved lymph nodes
A paired sample t-test could be applied to test the difference between MRI, CT, and PET-CT contours. Parameters used for comparison will include volume size, volume overlap, such as Dice similarity coefficients and Jaccard index, and surface distance maps including Hausdorff distance.
Up to 3 months
Change in functional response
Patients will be classified into responders and non-responders based on their PET signal which will serve as the reference method for response assessment. Although this is a little different from the three group analysis of variance (ANOVA) used in the power calculation, it is expected that there will be similar high power when the partial responders and non-responders are combined. Receiver operating characteristic (ROC) analysis will be used to define a threshold of apparent diffusion coefficient (ADC) change to stratify between metabolic responders vs. non-responders.
Baseline to 3 months
Spatial concordance of multimodality imaging for whole image registration
A paired sample t-test will be used.
Up to 3 months
Temporospatial registrations of radioresistant sub-volumes
A paired sample t-test will be used. ROC analysis will be performed only for radioresistant sub-volumes to identify which diffusion weighted-MRI functional signal thresholds correlate with levels of tumor activity defined on PET.
Up to 3 months
Secondary Outcomes (1)
Change in ADC
Baseline to 4 weeks
Study Arms (1)
Diagnostic (diffusion-weighted MRI, 4D CT, FDG-PET)
EXPERIMENTALPatients undergo 15 imaging studies: 5 chest CT scans, 5 chest MRI scans, 5 PET scans. Each scan will be obtained before treatment begins, weeks 2 and 4 during radiation therapy, 3 months and 1 year following radiation therapy. THe chest CT obtained pre-treatment, at 3 months post treatment and 1 year post treatment are considered routine and would be obtained regardless of study participation. The pre-treatment PET scan is also considered routine. All other scans are being done for the purposes of this research.
