Overview
Clinically focused session covering most relevant aspect of MRI in gut imaging, including technique, recent advances, and clinical applications. The promising role of MRI relevant to hollow visceral imaging including quantitative biomarkers, evaluating disease burden, and treatment response is presented. The emerging role of gut MRI as comprehensive alternative to CT without radiation burden allowing for frequent follow-up is covered.

Target Audience
Practicing MR clinicians, MRI researchers looking to expand their clinical armamentarium or better understand the promising clinical scene for incorporating in translational research or advanced clinical applications.

Educational Objectives
As a result of attending this course, participants should be able to:
- Explain applicability and interpretation of recent MRI advances in gut imaging;
- Examine improved imaging techniques, parametric methods in evaluating disease burden and treatment response of gut tumor;
- Develop awareness of expanding panorama of imaging vasculitis, ischemia; and
- Recall recent technical parameters and protocols in gut imaging.

09:15		MRI Imaging in Rectal Cancer & Response Assessment View Presentation Video David Kim Keywords: Body: Digestive Rectal MR is central to the management of rectal cancer patients, driving management at initial presentation and after neo-adjuvant therapy. After neoadjuvant therapy at re-staging MRI, the issue of residual tumor versus post treatment fibrosis is of primary importance where ‘watch and wait’ without surgical resection is possible for a complete clinical response. Optimizing the MR protocol, including the addition of intra-rectal gel, can improve both T2W and DWI images which are core to distinguishing between residual tumor and fibrosis. In addition, knowledge of lymph node drainage patterns can augment the accuracy of lymph node status.
09:35		MRI in Small & Large Bowel Tumours: One-Stop Shop View Presentation Video Andrea Laghi Keywords: Body: Digestive In current clinical practice, MR imaging plays a limited role in the study of small and large bowel tumors, if we exclude rectal cancer. In fact, most patients with either a suspected small bowel neoplasm or with a need of colon cancer staging is referred to a MDCT evaluation. However, high soft tissue contrast, multiplanar imaging acquisition, as well as the possibility of performing functional studies make MR a promising technique to study these diseases. The possibility of using MRI in assessing small and large bowel tumors depends on the unmet clinical needs which cannot be fully satisfied by MDCT.
09:55		MRI Imaging in Vasculitis, Ischemia, Weaning Away from CT View Presentation Video Jeff Fidler Keywords: Body: Digestive, Body: Body, Cardiovascular: Angiography Patients with ischemia or vasculitis involving the bowel usually present with acute abdominal pain and are imaged with CT. However, there are several scenarios where MR may be utilized or preferred. This presentation will discuss MR protocol optimization to efficiently diagnose these conditions, explain the pathophysiology and imaging findings of these entities, and review differential diagnoses.
