4D-MRI for Precision Medicine in Cancer Treatment
This study is developing a new way to create detailed images of the lungs and liver using a technique called four-dimensional magnetic resonance imaging (4D-MRI). This imaging method creates 3D movies of your chest and abdomen as you breathe, helping doctors see how tumors move. The goal is to improve radiation therapy for lung and liver cancer by providing more precise information about tumor size, shape, and location. Researchers will measure the quality of these images and how accurately they show movement in healthy volunteers and patients with liver or lung cancer. You may be eligible if you are an adult with lung or liver cancer that is less than 7 cm and you are scheduled for radiation therapy.

What this trial measures
- Image quality metrics in healthy volunteerssingle imaging session, lasting up to 2 hours
General 4D-MRI image quality will be assessed based on signal-to-noise ratio, number of distinct images per breathing cycle, total necessary imaging time, and image quality index.
- Image quality metrics in cancer patientssingle imaging session, lasting up to 2 hours
We hypothesize that our ultra-quality 4D-MRI methodology will outperform 4D-CT for motion management of radiotherapy in the lungs and the liver. We will test this hypothesis by comparing image quality based on tumor volume consistency, number of trackable landmarks, motion measurement accuracy, and image quality index.
- DVF errors in healthy volunteers and cancer patientssingle imaging session, lasting up to 2 hours
We hypothesize that our motion modeling method based on 4D-MRI will outperform current DIR algorithms for respiratory motion estimation. We will test this hypothesis by comparing our method to five existing DIR algorithms, based on the magnitude error (Em) and the angular error (Ea) of the calculated deformation vector field (DVF).
