Dynamic Magnetic Resonance Imaging (MRI) for Lung Tumor Motion and Lung Function (GCC 0943)
Radiation treatment for each patient with cancer is designed based on CT scans. We know that tumors in the chest and abdomen move when you breathe. Because of this, there can be differences between planned treatment and the treatment actually delivered to the body. Usually with radiation a safety margin is added to ensure that radiation hits the entire tumor. This can damage healthy parts of the body because the exact location of the tumor is unknown.
Magnetic resonance imaging (MRI) is a painless and safe diagnostic procedure that uses a powerful magnet and radio waves to produce detailed images of the body's organs and structures, without the use of X-rays or other radiation.
The research doctors are studying to see if the position of a tumor can be tracked using MRI scans and tracking sensors placed on the skin. MRI scans and the tracking system used to calculate the location and position of the tumor are both FDA approved technologies.
The research doctors will also use the MRI scans to evaluate any changes in your lung function during and following your radiation treatments.
In this study the participant will undergo a series of MRI scans with and without contrast dye.
This study is being funded through grants from the National Institutes of Health (NIH).
|Study Design:||Time Perspective: Prospective|
|Official Title:||Dynamic MRI for Lung Tumor Motion and Lung Function|
- To assess whether dynamic MRI without contrast and external surrogates can be used to determine real-time lung tumor position. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To assess whether lung perfusion after radiation therapy measured using dynamic MRI with contrast can be associated with radiation dose. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
|Study Start Date:||November 2009|
|Estimated Study Completion Date:||November 2017|
|Estimated Primary Completion Date:||November 2015 (Final data collection date for primary outcome measure)|
This is a pilot study and there is only one group.
In this protocol, we seek to assess whether tumor motion can be inferred using dynamic MRI and external surrogates. We propose to (1) investigate the feasibility of tracking the real-time tumor position using dynamic MRI and inferring tumor position using external surrogates placed on the skin of the subject and (2) determine lung function during and following radiation by assessing lung perfusion maps obtained via dynamic MRI with dose maps in order to determine image-based biomarkers for lung toxicity following radiation therapy.
