Magnetic Resonance Imaging of Head and Neck Emergencies, a Symptom-Based Review, Part 2
This article provides a symptom-based approach to nontraumatic head and neck pathologic conditions most relevant to emergency head and neck MR imaging, emphasizing relevant anatomy, “do not miss” findings affecting clinical management, and features that may aid differentiation from potential mimics. Essential MR sequences and strategies for obtaining high-quality images when faced with patient motion and other technical challenges are also discussed.

Musculoskeletal Trauma and Infection
MR is often the most definitive imaging for assessment of musculoskeletal trauma and infection. Although it is not possible to address all the intricacies of these complex topics in a single article, this review will attempt to provide a useful toolbox of skills by discussing several common clinical scenarios faced by emergency radiologists in interpretation of adult trauma and infection. These scenarios include MR assessment of hip and pelvic fracture, traumatic soft tissue injuries, septic arthritis, soft tissue infection, and osteomyelitis.

Emergent Magnetic Resonance Angiography for Evaluation of the Thoracoabdominal and Peripheral Vasculature
Thoracoabdominal and peripheral vasculature pathologies include a variety of severe and life threatening conditions that may be encountered in the emergent setting. Computed tomography angiography (CTA) is the first-line modality for imaging of the vasculature in this context, but magnetic resonance angiography (MRA) also plays an important and emerging role in the evaluation of carefully selected patients. Intravenous (IV) iodinated contrast is necessary for CTA, although MRA is most useful in patients who cannot receive IV iodinated contrast for reasons including prior severe allergic-like reaction to iodinated contrast,...

Use of MR in Pancreaticobiliary Emergencies
This article presents the MR protocols, imaging features, diagnostic criteria, and complications of commonly encountered emergencies in pancreaticobiliary imaging, which include pancreatic trauma, bile leak, acute cholecystitis, biliary obstruction, and pancreatitis. Various classifications and complications that can arise with these conditions, as well as artifacts that may mimic pathology, are also included. Finally, the emerging utility of abbreviated MR protocols is discussed. (Source: Magnetic Resonance Imaging Clinics of North America)

Magnetic Resonance Imaging of Acute Abdominal Pain in the Pregnant Patient
Evaluation of a pregnant patient presenting with acute abdominal pain can be challenging to accurately diagnose for a variety of reasons, and particularly late in pregnancy. Noncontrast MR remains a safe and accurate diagnostic imaging modality for the pregnant patient presenting with acute abdominal pain, following often an initially inconclusive ultrasound examination, and can be used in most settings to avoid the ionizing radiation exposure of a computed tomography scan. Pathologic processes discussed in this article include some of the more common gastrointestinal, hepatobiliary, genitourinary, and gynecologic causes o...

ED MRI: Safety, Consent, and Regulatory Considerations
MRI is a vital examination in the emergency department, especially in patients with stroke, spinal cord compression, cardiovascular emergencies, appendicitis, and trauma. It is important to consider its underlying safety hazards because of its strong magnetic and radio frequency fields. Multiple resources are available to guide radiology departments on the safe functioning of an MRI site. Four-zone site layout, MR compatibility labeling, MR personnel training, detailed screening process, access control, and appropriate implementation of safety policies and procedures are all necessary to maintain a safe and hazard-free MR ...

Preface
All significant medical advances ultimately depend on advances in technology, extending the sensitivity of the MD ’s eyes, ears, and fingers—Robert H. Ackerman, MD, MPH, 2015In a 2001 Medscape survey, physicians were asked to rank the 30 most important, impactful medical innovations of the prior 25 years; computed tomography (CT) and MR imaging were ranked number 1, at the top of this list. Indeed, since th e invention of the stethoscope in 1816, technological developments have continued at an ever-increasing pace to enhance the ability of health care providers to diagnose, treat, and manage diverse diseases.

Imaging Penile and Scrotal Trauma
As a complement to computed tomography and ultrasound for the emergency evaluation of penile and scrotal trauma, MR imaging provides unique advantages and anatomic delineation in the acute care setting. Rapid recognition of traumatic injuries helps guide appropriate clinical and surgical care to prevent long-term comorbidities. It is important for the radiologist to understand and identify these findings to optimize patient care in the emergency setting. (Source: Magnetic Resonance Imaging Clinics of North America)

Pediatric Emergency MRI
There is an overall increase in the use of imaging in the pediatric emergency room setting, which is accompanied by a reduction in computed tomography examinations performed mainly due to the increased awareness of the risks of ionizing radiation. Advances in MRI technology have led to shortened scan time, decreased motion sensitivity, and improved spatial resolution. With increased access to MRI in the emergency room setting, the goal of this article is to review major applications of MR in pediatric emergency room patients.

Foreword
“You want to order a what?… Why do you need an MRI performed on a patient from the emergency room?”…. This was the common reply when I was a resident and junior faculty when a request was made for an emergent MRI from the ER, …which was really not that long ago… ☺. Well, …times have certainly changed, and the utilization of MR ordered from the emergency room has substantially increased with many institutions now installing MRI units in the ER.
