MSK MRI 101: Practical Considerations for Anatomy & Techniques

Onsite Tutorial

Saturday, 07 May 2022

ICC Capital Suite 7 & 12

13:00 - 17:00

Moderators:
MSK MR Tutorial I: Eros Montin
MSK MR Tutorial II: Melissa Hooijmans

Skill Level: Basic to Advanced

Session Number: ET-04

Session Number: ET-04

Overview
This course will provide an introduction to MSK MRI anatomy and techniques, including a review of protocol options, pitfalls and artifacts for MSK MRI, and basic MRI anatomy in health and common diseases for the most common joint exams (hand/wrist, foot/ankle, shoulder, hip, and knee). This course is designed primarily to benefit non-clinical practitioners of MRI but will also provide value for MSK radiologists in better understanding the mechanisms of MR contrast for MSK tissues including bone, muscle, tendons/ligaments, and cartilage.

Target Audience
Physicists, engineers, trainees, early stage MSK radiologists, and non-MSK radiologists.

Educational Objectives
As a result of attending this course, participants should be able to:
- Explain the options and basic mechanisms of tissue contrast for MSK MR;
- Apply these options and basic mechanisms to protocol development and management; - Describe MSK MR anatomy for the most common joint exams; and
- Describe MRI of basic disease processes in MSK such as trauma and osteoarthritis.

	MSK MR Tutorial I
13:00		MSK MR Protocols View the Presentation Feliks Kogan MRI has become the hallmark for imaging of the musculoskeletal system due to its ability to image MSK tissues at high resolutions with multiple contrasts. Tailoring MRI sequences allows for optimization of anatomy or pathology of interest, removal of fat, imaging at higher resolutions or with more signal to noise, among other advantages. In this educational talk, we will discuss the MRI image contrast mechanisms, methods for suppression of fat signal, common MSK MRI pulse sequences and image considerations. Further, we will briefly cover novel MSK imaging approaches including accelerated imaging and reconstruction, non-cartesian MRI, bilateral scanning, and contrast/non-contrast imaging.
13:30		Artifacts and Pitfalls in MSK MR Imaging View the Presentation Andrew Fagan Image artifacts are commonly encountered in musculoskeletal MRI, and can lead to difficulties in correct image interpretation. While some artifacts are very obvious in an image, and the challenge then becomes one of ‘reading around’ the artifact, others can be more subtle and could be easily misinterpreted as a pathology. Understanding the source of an artifact can help to minimize its prevalence during set-up/scanning, or to differentiate artifact from genuine pathology when present in an image. This interactive talk will present a range of common (and some not-so-common) image artifacts, and discuss their source and strategies to minimize their impact.

14:30		MR Anatomy of the Knee View the Presentation Hakan Ilaslan
15:00		Break & Meet the Teachers
15:30		MR Anatomy of the Foot and Ankle Video Unavailable Carolyn Sofka Currently available MR pulse sequences for daily work evaluating foot and ankle pathology will be presented. Anatomy and specific foot and ankle disorders will be reviewed with an emphasis on progressive collapsing foot deformity, the spring and deltoid ligaments and articular cartilage injuries and repair and their MR appearances. A discussion of protocol considerations in the setting of metal will also be included, specifically with regards to imaging the painful total ankle replacement.
16:00		MR Anatomy of the Hip View the Presentation Benjamin Fritz
16:30		MR Anatomy of the Shoulder View the Presentation Francis Baffour This presentation will review the anatomy of the shoulder with specific attention to structures identified on magnetic resonance imaging. The anatomy of the shoulder will be discussed in the context of clinical cases.
