Application of Magnetic Resonance Imaging (MRI) to Radiotherapy
Modern radiotherapy takes advantage of advanced imaging modalities (CT, MRI, PET, Ultrasound…) for tumor and normal tissue identification. With the improved targeting accuracy, highly conformed radiation fields can be used to avoid critical organs and minimize treatment complications. Among all imaging modalities used by modern radiotherapy, MRI is unique in that it can provide both anatomic and functional information of the tumors and normal tissues. In this chapter, we will focus on the use of MRI for radiotherapy treatment planning process and for monitoring the treatment outcomes.
