Educational Session:
Body MRI Applications in the Emergency Department
Skill Level: Intermediate
Organizers: Ivan Pedrosa, M.D., Scott B. Reeder, M.D., Ph.D. & Edwin J.R. van Beek, M.D., Ph.D., M.Ed., FRCR
Monday 09 May 2016 |
Overview
This two-hour course focuses on body MRI applications in evaluating
acutely ill patients in the Emergency Department. Emphasis will be made
on presenting the technical challenges and opportunities for the
implementation of fast, optimized body MRI protocols for evaluation of
abdominal emergencies. MRI protocols for evaluation of patients with
suspected pulmonary embolism will be presented. A comprehensive review
of MR venography techniques will be discussed.
Target Audience
This course is aimed at radiologists, imaging scientists and MR
technologists who wish to review the state-of-art MRI protocols for
assessment of acutely ill patients in the Emegency Department and their
implementation into routine clinical practice.
Educational Objectives
Upon completion of this course, participants should be able to:
- Implement optimized, fast
protocols for evaluation of emergency patients;
- Demonstrate the utility of
MRI in the diagnosis of Acute Appendicitis from the perspective of
the Emergency Department Physician;
- Convey the implementation of
optimized MRA protocols for the expeditious assessment of acute
pulmonary embolism; and
- Illustrate the application of
optimized MRV protocols for assessment of acute venous conditions in
the body.

MRI in Acute Appendicitis: The Emergency Physician
Perspective
Michael D Repplinger1
1Emergency Medicine, University of Wisconsin
- Madison, Madison, WI, United States
In this presentation, we will discuss the diagnostic
accuracy of MR to diagnose appendicitis, both in the
general population and in select cohorts. Additionally,
we will discuss the evidence for various MR sequences
(unenhanced, intravenous contrast-enhanced, and DWI) as
well as the affect of radiologist expertise in abdominal
MR on diagnostic accuracy. Finally, we will discuss how
using MR in the emergency department setting impacts
patient care, particularly their timely evaluation.

Pulmonary MRA
Jeffrey H. Maki1
1Radiology, University of Washington,
Seattle, WA, United States
Accurately diagnosing pulmonary embolism is clinically
vital, with CT Pulmonary Angiography (CTPA) the most
often used diagnostic tool. CTPA, however, is not
without limitations. The largest of these is ionizing
radiation, which for younger patients can significantly
increase lifetime attributable cancer mortality risk,
especially considering a positive CTPA rate of <10%.
Additionally, many patients have iodine allergies or are
pregnant. Pulmonary MRA is an emerging technology that
has benefited from new technical advances and recently
proven to have a high negative predictive value similar
to CTPA. Pulmonary MRA should be considered in the young
and those where CTPA is contraindicated.

MRV
Charles Kim1
1Radiology, Duke University Medical Center,
Durham, NC, United States
MR venography can play a vital role in the diagnosis and
treatment planning for acute venous thrombosis if
well-developed protocols and referral patterns are in
place. The two primary emergency indications for MR
venography will be discussed in detail: acute
iliofemoral / lower extremity DVT and acute SVC
syndrome. The ideal MR venography contrast agents will
be reviewed, as well as optimized MR venography
protocols. This lecture will provide the audience with
pertinent clinical information, pros and cons of various
competing imaging modalities, and emphasize key
reporting topics for these various pathologies.
