Summary
Brief summary (as posted)
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.

- type
- EXPERIMENTAL
- label
- Diagnostic (diffusion-weighted MRI, 4D CT, FDG-PET)
- description
- Patients 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.

- Device: diffusion-weighted magnetic resonance imaging
- Device: 4-dimensional computed tomography
- Radiation: fludeoxyglucose F 18
- Device: FDG-PET
Primary outcomes (4)
- measure
- Measurement of gross tumor volume and involved lymph nodes
- timeFrame
- Up to 3 months
- description
- 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.
