Sunrise Course

ORGANIZERS: Masako Kataoka, Nandita DeSouza, Jurgen Fütterer, Hero Hussain, Katja Pinker-Domenig, Scott Reeder, Jeffrey Maki

Monday, 09 May 2022

ICC Capital Suite 10-11

08:00 - 09:00

Moderators: Martin Graves

Skill Level: Basic to Advanced

Session Number: S-M-03

Session Number: S-M-03

Overview
The series of talks covers hot topics in body MRI. The topics include:

1) MRI of gender imaging (prostate & female pelvis): Two specific areas of gender imaging that may be exploited in the clinic will be addressed--multiparametric MRI in metastatic ovarian cancer and low field MRI for prostate cancer screening.

2) MRI of the pancreas: From basic anatomy / protocols to more advanced techniques will be covered to highlight this hidden organ.

3) Multi-organ, COVID-19-related, vaccine-associated conditions on MRI: With wide-use of COVID-19 vaccination, reactive adenopathy and other vaccine-related reactions are completely new conditions that clinicians must know. The two talks cover the latest evidence and recommendations. Images of COVID-19-related multi-organ conditions are also covered.

4) MRI for moving organs (motility imaging): A unique opportunity reviewing technical aspect and interpretation skills required for MRI of moving organs.

Target Audience
Basic to advanced, both clinicians and Ph.D.s interested in body MRI.

Educational Objectives
As a result of attending this course, participants should be able to:
- Describe the utility of multiparametric MRI over CT for assessing metastatic ovarian cancer;
- Recognize what is needed to make prostate cancer screening viable with low field MRI;
- Describe the requirements for basic and advanced imaging of the pancreas;
- Recognize the imaging features of multi-organ COVID-19-related or vaccine-associated pathology; and
- Describe the techniques required for MRI of moving organs and interpret their imaging appearances.

	08:00		Embrace the Motility: Visualizing Motion in the Abdomen View the Presentation Catharina de Jonge Assessment of the (patho)physiology of the gastrointestinal (GI) tract is important for diagnosis and treatment monitoring of gastrointestinal diseases. Due to its location in the body, it's length and physiology, the GI tract is a complicated organ to investigate. Standard measurement methods, like manometry, are invasive and cannot assess the entire GI tract. Therefore MR motility methods are on the rise. This educational talk will review the existing and emerging techniques to capture and quantify motility with cine-MRI and explore the clinical implementation.
	08:30		Reject the Motility: Mitigating Motion in the Abdomen View the Presentation Diego Hernando Body MRI is complicated by the presence of multiple sources of physiological motion, including respiratory, cardiovascular, peristaltic, and bulk patient motion. If unaddressed, these sources of motion can lead to multiple artifacts, particularly ghosting and blurring. Motion artifacts can also lead to bias and poor precision in quantitative MR methods. This educational talk will review the major challenges of motion in body MRI, as well as existing and emerging solutions. Importantly, this talk will attempt to outline the benefits and drawbacks of each motion mitigation method.
