Evaluation of Tumor Motion Management Strategies in Radiotherapy Using 4D-MRI
This research is being done to understand the movement of tumors in the chest as a person breathes using 4D MRI imaging. Precision in radiation treatment is limited by the ability to detect and predict the possible locations of the tumor in the breathing cycle. Other methods are available to detect a tumorâ??s movement, but these alternatives have limitations and risks. A better understanding of tumor motion will enable doctors to better target chest tumors with radiation.
Participants are eligible for this trial if they have a histologically-confirmed primary lung cancer (non-small cell OR small cell) and plan to undergo external radiation treatment for their lung cancer. Participants who cannot undergo MRIs, have a a cardiac device or other electronic or metal implant and/or are pregnant are not eligible for this study.
As a part of this study partipants will be asked to undergo two research MRIs performed at different times during standard radiation therapy treatment. The first MRI will be done just before the start of radiation treatment and is considered research. The second MRI will be done about halfway through radiation treatment and is also considered research. Participants will be a part of this study for about 2 months. There is no follow-up for this trial.
