Acute pelvic pain in pediatric female patients is a common cause of emergency room visits. Imaging plays a crucial role in the clinical evaluation of these patients. Pelvic pain in female children can result from various pathologies. Ultrasound is the preferred first line imaging study; however, magnetic resonance imaging (MRI) is a helpful adjunct after hours, as it is available 24/7 in many institutions. Advantages of MRI include superior delineation of anatomy and higher tissue contrast resolution, particularly of the small pelvic structures...

Patients presenting with a painful swollen leg are not infrequently encountered at the emergency department and can pose a diagnostic dilemma for attending physicians. The potential causes of leg pain and swelling include trauma, infection, inflammation, and neurogenic, vascular, and iatrogenic conditions; with magnetic resonance imaging (MRI) being an important tool in evaluation. We describe the MRI features of various conditions causing painful swollen legs. We also discuss the differential diagnosis and the useful clinical and laboratory findings that radiologists should be aware of, in order to arrive at an accurate diagnosis...

Transient restricted diffusion and increased T2 signal intensity within the splenium of the corpus callosum is an increasingly recognized albeit uncommon imaging feature in the setting of acute encephalitis and antecedent viral illness. This review will discuss three index cases obtained from an institutional databank. Additionally, the current understanding of the underlying neurophysiologic pathogenesis will be discussed together with differential clinical and imaging diagnostic considerations, treatment options, and outcome metrics...

Kristopher McKenzie, Milita Ramonas, Michael Patlas, Douglas S Katz
PURPOSE: To examine trends in female authorship in the journal Emergency Radiology from January 1994 to December 2014. METHODS: We obtained institutional review board approval for our study. We retrospectively reviewed a total of 1617 articles published in the journal Emergency Radiology over a 20-year period. Original articles, case reports, review articles, and pictorial essays were included. The first and last position author's gender was categorized as female or male...

REVIEW
Simon Long, Jared Garrett, Peeyush Bhargava, Gabriel Aguilar, Alberto Simoncini, Guillermo Sangster
Rhabdomyolysis has traditionally been a clinical diagnosis with healthcare providers utilizing historical context, physical exam, and laboratory data to arrive at a diagnosis. However, there are myriad imaging findings that may be corroborative and support the presumptive diagnosis. This paper seeks to review imaging findings associated with rhabdomyolysis using different modalities including radiography, sonography, computed tomography (CT), magnetic resonance imaging (MRI), and bone scintigraphy.

PURPOSE: The purpose of this study was to identify factors at the time of presentation which could quickly exclude or identify renal dysfunction in blunt trauma patients, thus negating serum measurement of renal function prior to contrast-enhanced imaging and expediting care. METHODS: Patients, >18 years old, without renal failure, presenting after blunt trauma, with serum creatinine measured at presentation, were retrospectively studied at a single center. Variables recorded at presentation including vitals, mechanism, and past medical history were analyzed using multivariate regression analysis to identify independent predictors of abnormal renal function...

PURPOSE: Pregnancy increases the risk for thromboembolic disease. CT pulmonary angiogram (CTPA) is widely used for the diagnosis of pulmonary embolus (PE); however, a significant number of scans are suboptimal or non-diagnostic in pregnant patients. This phenomenon is attributed to physiology during the gravid state. The aim of this study is to examine whether all stages of pregnancy are similarly at risk for suboptimal scans. METHODS: Pregnant patients who had CTPA scans between February 2008 and November 2014 were included...

We describe a case of ischemia complicating acute small-bowel obstruction in which retrospective on-demand spectral analysis using dual-layer spectral detector computed tomography (CT) provided a higher degree of confidence pertaining to the diagnosis. Dual-layer spectral detector CT enables retrospective on-demand spectral analysis, including virtual monochromatic imaging, iodine mapping, and determining the effective atomic number Z, without the need of a pre-scan setting requiring a special protocol, particularly facilitating emergency situations...

Ureteral injuries are uncommon in trauma patients, accounting for fewer than 1% of all injuries to the urinary tract. These uncommon, yet problematic, injuries can often be overlooked in the standard search pattern on abdominal and pelvic multi-detector CT (MDCT) images, as radiologists focus on more immediate life-threatening injuries. However, early diagnosis and management are vital to reduce potential morbidity. If there is a high clinical index of suspicion for ureteral injuries with penetrating or blunt trauma, or if there is suspected iatrogenic ureteral injury, delayed-phase/urographic-phase MDCT images are essential for confirming the diagnosis...

PURPOSE: Tha aims of this study were to identify the incidence of femoral head fractures in the setting of acetabular fractures and to determine the relationship between acetabular fracture pattern, the degree of acetabular fracture displacement, and the incidence of femoral head fractures. MATERIALS AND METHODS: This is a retrospective cross-sectional study of 274 patients with 300 acetabular fractures diagnosed on pelvic CT. Acetabular fractures were categorized using the Judet-Letournel classification system...

A 94-year-old Korean woman was seen in the Emergency Department after a fall. CT examination of the maxillofacial region found multiple small linear metallic densities in the subcutaneous soft tissues of the face. The appearance of these densities was unchanged when compared to a study performed 2 years prior; however, the imaging interpretations of these densities were markedly different. Additional imaging during the course of her hospital stay demonstrated numerous similar densities in the breasts, abdomen, hips, and legs-finally diagnosed as "charm needles...

PURPOSE: Ventilation and perfusion (VQ) imaging is common following suboptimal CT pulmonary angiogram (CTPA) for pulmonary embolism (PE) evaluation; however, the results of this diagnostic pathway are unclear. The purpose of our study is to determine the incidence of PE diagnosed on VQ scans performed in patients with suboptimal CTPAs. METHODS: One hundred twenty-two suboptimal CTPAs with subsequent VQ scans within 1 week were retrospectively identified. VQ reports utilizing modified ​prospective investigation of pulmonary embolism diagnosis (PIOPED) and prospective investigative study of acute pulmonary embolism diagnosis (PISAPED) criteria were evaluated for presence of PE; intermediate probability, high probability, and PE present were considered PE positive...

PURPOSE: We evaluated the corona mortis (CM) anatomy by means of three-dimensional computerized tomography angiographic (CTA). METHODS: Patient demographic, anastomosis incidence, artery diameter, artery distance from the symphysis pubis, and pelvic size (distance between both acetabular upper labrum) parameters were assessed. The 100 patients included 66 males and 34 females (average age of 67.8 years). RESULTS: There were 66 (33%) arterial anastomoses in the 200 evaluated arteries, 30 in the right side and 36 in the left side, 36 unilaterally and 15 bilaterally...

PURPOSE: Computed tomography (CT) examinations, often using high-radiation dosages, are increasingly used in the acute management of polytrauma patients. This study compares a low-dose polytrauma multi-phase whole-body CT (WBCT) protocol on a latest generation of 16-cm detector 258-slice multi-detector CT (MDCT) scanner with advanced dose reduction techniques to a single-phase polytrauma WBCT protocol on a 64-slice MDCT scanner. METHODS: Between March and September 2015, 109 polytrauma patients (group A) underwent acute WBCT with a low-dose multi-phase WBCT protocol on a 258-slice MDCT whereas 110 polytrauma patients (group B) underwent single-phase trauma CT on a 64-slice MDCT...
