    MRI has played a supportive role in radiation therapy for over two decades, and current observations and guidance suggest that this role will be increasing over the next several years. This symposium will explore some of the advances and questions related to using MRI as a key, if not solitary, imaging methodology in the planning of radiation therapy treatments. Both external beam radiation therapy as well as brachytherapy will be explored. Issues such as distortion, image quality, scanning time, optimization of MRI protocols, integration in the radiation therapy workflow, and knowledge and practice information of use to non-diagnostic physicists will be explored.

    Learning objectives:

    1. Understand the current and potential near future roles of MRI external beam radiation therapy
    2. Understand current recommendations and future directions for MRI in brachytherapy
    3. Understand the quality assurance and commissioning needs for MRI systems for the above uses
    4. Understand the characteristics of modern MRI systems and the modifications and additional features that may facilitate radiation therapy use

    Diagnostic Imaging is evolving from a modality where the emphasis is on the acquisition and interpretation of image data by radiologists to one where imaging devices may be used as measurement devices that are able to produce quantitative results. Some examples of quantitative measured values are already in clinical practice, including coronary artery calcium scores from CT, Standard Uptake Values (SUV) in PET imaging and Diffusion Weighted Imaging (DWI) in MRI. Clinical and clinical research applications of quantitative anatomical and functional imaging biomarkers, including those focused on treatment assessment, have continued to dramatically expand. Studies at single centers have clearly demonstrated the potential of such applications. However, sources of bias and variance of quantitative imaging biomarkers have not previously been adequately investigated, thus limiting the implementation of robust methods to mitigate their effects. Therefore, when it comes to applications of such techniques across vendor platforms, centers, and time, challenges arise due to lack of standards, appropriate phantoms, and protocols.

    During the past few years, several quantitative imaging initiatives have been instigated. This symposium presentation will review selected applications of quantitative imaging biomarkers, illustrate some of the current challenges in broadening the use of such biomarkers, and discuss some of the current initiatives of various scientific and federal organizations that are focused on the standardization, qualification, and validation of quantitative imaging biomarkers.

    Educational Objectives:
    1. Understand selected applications of quantitative imaging biomarkers.
    2. Understand the factors that currently limit widespread acceptance and use of such quantitative imaging biomarkers, including sources of bias and variance.
    3. Understand some of the current initiatives focused on the standardization, qualification, and validation of selected quantitative imaging biomarkers.

    PET/MR is an exciting new addition to the suite of commercially available hybrid imaging technologies. Although, there has been continued research on the integration of PET and MR since the initial demonstration of the proof-of-concept in the mid-1990’s, it is only more recently that hybrid PET/MR systems have become a clinical reality. A number of different PET/MR integration designs were explored and crucial technological advancements were necessary before commercialization of clinical PET/MR systems became a reality.

    Learning Objectives:
    1. Present the historical development of PET/MR systems
    2. Overview of PET/MR image formation, artifacts, and clinical applications
    3. Design considerations, challenges, and technological advancements for clinical implementation of PET/MR
