Abstract	A pregnant patient with acute trauma is not commonly encountered by clinicians and radiologists. A multidisciplinary approach is key. Although radiography and ultrasound examination are frequently used modalities in the setting of maternal-fetal trauma, the fear of radiation should not preclude from carrying out a thorough diagnostic workup of the patient with a computed tomography scan. MRI mainly serves as a problem solving and follow-up modality. After stabilizing the mother, fetal well-being should be assessed with external fetal monitoring and a dedicated obstetric ultrasound examination. Radiologists should be familiar with the sonographic and computed tomography findings of catastrophic entities.

Abstract	Purpose: The novel coronavirus disease (COVID-19) pandemic has swept the globe, with a domino effect on medical education and training. In this study, we surveyed Canadian radiology residents to understand the impact of the pandemic on their residency training, strategies utilized by the residency programs in mitigating those impacts, and factors important to residents in the selection of educational resources on COVID-19. Methods: A 10-item questionnaire was distributed to 460 resident members of the Canadian Association of Radiologists. The survey was open for 2 weeks, with a reminder sent at half-way mark. Results: We received 96 responses (response rate: 20.9%). The 4 highest affected domains of training were daytime case volumes (92.4%), daytime schedules (87.4%), internal and external assessments (86.5%), and vacation/travel (83.3%). Virtual teaching rounds (91.7%), change in schedules to allow staying home (78.1%), and virtual/phone readouts (72.9%) were the most utilized strategies by the Canadian radiology residency programs. Overall stress of exposure to the disease was moderate to low (86.5%). A minority of the residents were redeployed (6.2%), although most (68.8%) were on standby for redeployment. Residents preferred published society guidelines (92.3%), review papers (79.3%), video lectures (79.3%), and web tools (76.9%) for learning about COVID-19 imaging manifestations. Conclusion: The COVID-19 pandemic has had a significant impact on various domains of the Canadian radiology residency programs, which has been mitigated by several strategies employed by the training programs.

Abstract	Dual energy CT (DECT) refers to the acquisition of CT images at two energy spectra and can provide information about tissue composition beyond that obtainable by conventional CT. The attenuation of a photon beam varies depends on the atomic number and density of the attenuating material and the energy of the incoming photon beam. This differential attenuation of the beam at varying energy levels forms the basis of DECT imaging and enables separation of materials with different atomic numbers but similar CT attenuation. DECT can be used to detect and quantify materials like iodine, calcium, or uric acid. Several post-processing techniques are available to generate virtual non-contrast images, iodine maps, virtual mono-chromatic images, Mixed or weighted images and material specific images. Although initially the concept of dual energy CT was introduced in 1970, it is only over the past two decades that it has been extensively used in clinical practice owing to advances in CT hardware and post-processing capabilities. There are numerous applications of DECT in Emergency radiology including stroke imaging to differentiate intracranial hemorrhage and contrast staining, diagnosis of pulmonary embolism, characterization of incidentally detected renal and adrenal lesions, to reduce beam and metal hardening artifacts, in identification of uric acid renal stones and in the diagnosis of gout. This review article aims to provide the emergency radiologist with an overview of the physics and basic principles of dual energy CT. In addition, we discuss the types of DECT acquisition and post processing techniques including newer advances such as photon-counting CT followed by a brief discussion on the applications of DECT in Emergency radiology.

Abstract	Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic kidney disorder with progressive renal function decline, and disease severity is determined based on the type of genetic mutation. The diagnosis is usually established at imaging, primarily at US, and is based on age-dependent criteria and the number of visible cysts. ADPKD is classified into class 1 (typical) and class 2 (atypical) according to the Mayo Clinic Imaging Classification (MCIC) system. Height-adjusted total kidney volume (TKV) has emerged as a predictor of future renal function decline and renal failure in ADPKD, and several methods can be used for estimation. MCIC class 1 ADPKD is further subdivided into five types based on height-adjusted TKV (A, B, C, D, and E). Patients with a larger height-adjusted TKV (ie, MCIC 1C-E) are at high risk for progression to end-stage renal disease and will potentially benefit from vasopressin receptor antagonists, which have been shown to reduce the rate of cyst growth and slow renal function decline. Other renal complications primarily relate to hemorrhage within cysts or cyst infections. Subtraction images are key for assessment of complex cysts when malignancy is suspected, as the presence of protein and blood can limit the assessment for an enhancing component. The radiologist has a central role in establishing a diagnosis, excluding mimics, identifying complications, assessing severity, and predicting future renal failure. Interventional radiologists play a therapeutic role in management of complications by cyst drainage, sclerotherapy, or embolization.

Abstract	Purpose: Despite several published reports on the value of imaging in acute blunt pancreatic trauma, there remains a large variability in the reported performance of ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). The purpose of this study is to present a systematic review on the utility of these imaging modalities in the acute assessment of blunt pancreatic trauma. In addition, a brief overview of the various signs of pancreatic trauma will be presented. Methods: Keyword search was performed in MEDLINE, EMBASE, and Web of Science databases for relevant studies in the last 20 years (1999 onward). Titles and abstracts were screened, followed by full-text screening. Inclusion criteria were defined as studies reporting on the effectiveness of imaging modality (US, CT, or MRI) in detecting blunt pancreatic trauma. Results: After initial search of 743 studies, a total of 37 studies were included in the final summary. Thirty-six studies were retrospective in nature. Pancreatic injury was the primary study objective in 21 studies. Relevant study population varied from 5 to 299. Seventeen studies compared the imaging findings against intraoperative findings. Seven studies performed separate analysis for pancreatic ductal injuries and 9 studies only investigated ductal injuries. The reported sensitivities for the detection of pancreatic injuries at CT ranged from 33% to 100% and specificity ranged from 62% to 100%. Sensitivity at US ranged from 27% to 96%. The sensitivity at MRI was only reported in 1 study and was 92%. Conclusion: There remains a large heterogeneity among reported studies in the accuracy of initial imaging modalities for blunt pancreatic injury. Although technological advances in imaging equipment would be expected to improve accuracy, the current body of literature remains largely divided. There is a need for future studies utilizing the most advanced imaging equipment with appropriately defined gold standards and outcome measures.

Abstract	Purpose: There are no published guidelines on the follow-up imaging of non-operatively managed blunt splenic trauma (BST). We conducted an international survey of emergency radiologists to determine the ideal patient population, time period, and technique for follow-up imaging of BST. Methods: An anonymous 10-question online survey was distributed via email to 34 emergency radiologists around the world. The survey was open for a 2-week period in 2019. A commercially available website (SurveyMonkey®) was used for survey generation and data acquisition. Results: We received 29 responses (85% response rate) primarily from USA, Canada, and Europe. Majority of the institutions handled > 1000 trauma cases (69%). The initial protocol consisted of arterial and portal venous phases (PVP) in 72% of responses. Sixty-two percent of the institutions did not have a routine protocol for follow-up imaging of BST. There was no consensus on which patients received follow-up imaging. The most frequent responses had been case-per-case basis or injuries above a set AAST grade (42% and 37%, respectively). There was no set time period for follow-up imaging, but MDCT was most often performed at 24-48 h. Dual-phase protocol was utilized most commonly (69%). Majority of the institutions (88%) utilized angioembolization for hemodynamically stable patients with contained vascular injury or active extravasation. Conclusion: There is no consensus on the optimal patient population or time period for follow-up imaging of BST. A dual-phase follow-up MDCT protocol is utilized for follow-up by majority of institutions.
