Magnetic Resonance Imaging (MRI) Solely For Liver Stereotactic Body Radiation Therapy (SBRT)

There is a potential role to systematically implement MRI to establish appropriate workflow
of the implementation for tumor motion management in liver SBRT. Compared to CT, MRI has
many significant advantages for radiotherapy planning, including superior tumor and
soft-tissue contrast, flexible imaging orientation, freedom from radiation exposure and
real-time imaging. MRI solely based liver SBRT will allow for more precise delineation of
target volume, less uncertainties in treatment planning, better motion management, and
potentially better treatment outcome
