The clinical manifestations of abdominal and pelvic organ torsion can often be non-specific and can affect a wide range of ages and demographic groups. Radiologists have a key role in not only establishing the diagnosis of organ torsion, but also in the assessment of potential complications. As multiple imaging modalities may be utilized in the evaluation of abdominal and pelvic pain, recognizing the various appearances of organ torsion is important to ensure early diagnosis and thereby reducing patient morbidity and mortality, particularly since abdominal and pelvic organ torsion may not be clinically suspected at the time of initial patient presentation.

OBJECTIVES/OBJECTIVE:To obtain information from radiology departments throughout Europe regarding the practice of emergency radiology METHODS: A survey which comprised of 24 questions was developed and made available online. The questionnaire was sent to 1097 chairs of radiology departments throughout Europe using the ESR database. All data were collected and analyzed using IBM SPSS Statistics software, version 20 (IBM). RESULTS:A total of 1097 radiologists were asked to participate, 109 responded to our survey. The response rate was 10%. From our survey, 71.6% of the hospitals had more than 500 beds. Ninety-eight percent of hospitals have an active teaching affiliation. In large trauma centers, emergency radiology was considered a dedicated section. Fifty-three percent of institutions have dedicated emergency radiology sections. Less than 30% had all imaging modalities available. Seventy-nine percent of institutions have 24/7 coverage by staff radiologists. Emergency radiologists interpret cross-sectional body imaging, US scans, and basic CT/MRI neuroimaging in more than 50% of responding institutions. Cardiac imaging examinations/procedures are usually performed by cardiologist in 53% of institutions, while non-cardiac vascular procedures are largely performed and interpreted by interventional radiologists. Most people consider the European Diploma in Emergency Radiology an essential tool to advance the education and the dissemination of information within the specialty of emergency radiology. CONCLUSION/CONCLUSIONS:Emergency radiologists have an active role in the emergency medical team. Indeed, based upon our survey, they have to interact with emergency physicians and surgeons in the management of critically ill patients. A broad skillset from ultrasonography and basic neuroimaging is required. KEY POINTS/CONCLUSIONS:• At most major trauma centers in Europe, emergency imaging is currently performed by all radiologists in specific units who are designated in the emergency department. • Radiologists in the emergency section at present have a broad skillset, which includes cross-sectional body imaging, ultrasonography, and basic neuroimaging of the brain and spine. • A dedicated curriculum that certifies a subspecialty in emergency radiology with a diploma offered by the European Society of Emergency Radiology demonstrates a great interest by the vast majority of the respondents.

Everyone at all levels in academic radiology is supposed to know how to read an original research article or a review article and to evaluate it critically, to participate in writing such manuscripts, and, as one becomes more senior, to participate in the peer review process, yet there is little formal teaching in our experience as to how to do these inter-related activities throughout radiology training. The purpose of this review article is therefore to provide our perspective - from the junior trainee to the senior radiology attending - as to how one should be reading, reviewing, and writing the imaging literature, and also providing guidance from other thought leaders in this area, and from the literature itself. We hope to inspire radiology trainees and radiologists at all levels, particularly those in academic careers, to more fully participate in peer review and in radiology publication.

Endometrial abnormalities develop in female patients of all ages. Symptoms related to endometrial pathologies are among the most common causes of gynecologist office visits, with the radiologists playing an important role in endometrial evaluation. In some instances, the radiologist may be the first physician to note endometrial pathology. In this article, we will provide a comprehensive review of radiologic modalities utilized in the evaluation of the endometrium, as well as the imaging appearance of various endometrial disease processes.

Maternal serum alpha-fetoprotein is a valuable laboratory test used in pregnant women as an indicator to detect certain clinical abnormalities. These can be grouped into four main categories: fetal factors, pregnancy complications, placental abnormalities, and maternal factors. Imaging is an invaluable tool to investigate the various etiologies leading to altered maternal serum alpha-fetoprotein. By reading this article, the radiologist, sonologist, or other health care practitioner should be able to define the probable pathology leading to the laboratory detected abnormal maternal serum levels, thus helping the clinician to appropriately manage the pregnancy and counsel the patient.

Firearm-related injuries, or gunshot wounds (GSWs), are among the most important worldwide public health problems, resulting in considerable annual morbidity, disability, and mortality. GSWs to the abdomen and pelvis are associated with substantial injuries to multiple organs and tissues. Imaging plays an important role in identifying these injuries, dictating nonoperative management, and determining imaging and clinical follow-up, as well as helping manage potential long-term complications. CT is the primary imaging modality used to evaluate these injuries and their complications, including use of reconstructed multiplanar volume-rendered images. The authors discuss the ballistics and mechanisms of firearm injury, CT findings, trajectory analysis, and applications of different imaging modalities above and beyond CT in evaluation of GSWs. Imaging findings and classifications of the severity of injuries to solid and hollow organs and vascular, musculoskeletal, and neurologic systems are reviewed. Key complications associated with gunshot injuries to the abdomen and pelvis are presented. The challenges of imaging in the acute trauma setting and potential pitfall mimics at imaging, particularly at CT, are also described. A step-by-step guide for thorough and comprehensive evaluation of GSWs to the abdomen and pelvis is introduced, with tips for optimizing effective communication with the clinical team.

The purpose of this article is to describe arterial and venous thromboembolism in the abdomen, pelvis, and lower extremities. Eight-two COVID patients with abdominal ultrasound or CT were retrospectively compared with non-COVID patients for thromboembolism and solid-organ infarction. Nine (11%) COVID-19 patients had thromboembolic findings with medium to large-sized arterial thrombi in 5/82. One non-COVID patient had known portal vein thrombus on CT. Thromboembolic findings occurred more frequently in patients with than without COVID-19 (p=0.02).

A wide range of benign and malignant processes can affect one or both fallopian tubes. Familiarity with and recognition of the characteristic imaging features of these diseases and conditions are imperative for accurate diagnosis and prompt patient management. Disorders including pelvic inflammatory disease (hydrosalpinx and pyosalpinx in particular), isolated tubal torsion and ovarian torsion with fallopian tube involvement, endometriosis manifesting as hematosalpinx and adhesions, ectopic pregnancy, and malignancies are the most important entities that radiologists should be familiar with when assessing the fallopian tubes. Some fallopian tube diseases are self-limiting, while others can result in infertility or even potentially life-threatening infection or bleeding if left untreated. Therefore, correct diagnosis is important for appropriate life-saving treatment and preserving fertility. Understanding the physiologic features of the fallopian tube and the role of this organ in the pathogenesis of pelvic neoplasms is equally important. Knowledge of what to expect in a patient who has undergone uterine and fallopian tube interventions, such as uterine ablation and fallopian tube ligation, and of the potential associated complications (eg, postablation sterilization syndrome) also is pertinent. The imaging modalities used for the evaluation of fallopian tube disease and patency range from commonly used examinations such as US, CT, and MRI to other modalities such as hysterosalpingography and hysterosonography performed by using US contrast material. The ability to differentiate fallopian tube conditions from other adnexal and pelvic pathologic entities by using a variety of imaging modalities allows the radiologist to make a timely diagnosis and ensure proper clinical management.
