Positive rate and quality assessment of CT pulmonary angiography in sickle cell disease: a case ‒control study
ConclusionsThis study revealed a relatively low positive rate of CTPA in both SCD patients and the control group. However, SCD was significantly associated with suboptimal image quality due to inadequate contrast enhancement of the pulmonary artery. Further research is needed to identify measures that can enhance the quality of CTPA studies in SCD patients and to establish a specific imaging protocol for this patient population.

Point-of-care ultrasound: impact on emergency department length of stay for suspected lower extremity DVT
ConclusionED POCUS scans decrease the amount of time between order placement and disposition when compared to RADUS. POCUS significantly decreases length of stay in the ED when RADUS is not available. (Source: Emergency Radiology)

Artificial intelligence CAD tools in trauma imaging: a scoping review from the American Society of Emergency Radiology (ASER) AI/ML Expert Panel
ConclusionsTrauma imaging CAD tools are likely to improve patient care but are currently in an early stage of maturity, with few FDA-approved products for a limited number of uses. The scarcity of high-quality annotated data remains a major barrier. (Source: Emergency Radiology)

A survey of ASER members on artificial intelligence in emergency radiology: trends, perceptions, and expectations
ConclusionASER member respondents are in general optimistic about the impact of AI in the practice of emergency radiology and its impact on the popularity of emergency radiology as a subspecialty. The majority expect to see transparent and explainable AI models with the radiologist as the decision-maker. (Source: Emergency Radiology)

CTPA ordering trends in local emergency departments: are they increasing and did they increase as a result of COVID-19?
ConclusionOver the studied period from 2018 –2022, the overall number of CTPA studies ordered by local emergency departments has increased, in line with literature reports from other locations. There was also a correlation between the onset of the COVID-19 pandemic and CTPA positivity rates, possibly secondary to the prothrombotic nature of this infection or the increase in sedentary lifestyles during lockdown periods.

An uncommon case of high-pressure paint gun injury to the orbit with multimodality evaluation and literature review
We present an unfortunate case of high-pressure paint injury to the right orbit of a young patient. High-pressure injection injury presents with a unique injury mechanism and resultant deep tissue damage. The superficial appearance of the entry site injury is deceiving; therefore, a thorough evaluation is necessary. Debridement is usually required if foreign body material is present. Antibiotics and steroids are commonly used in such cases. (Source: Emergency Radiology)

Active upper aerodigestive tract hemorrhage in patients with head and neck cancers: the “dot-in-sludge” sign
Abstract
Active extravasation into the upper aerodigestive tract is a dramatic and potentially life-threatening complication in patients with head and neck cancers. It prompts presentation to the emergency room and subsequent urgent imaging to identify the source of hemorrhage. Imaging of these patients may be complicated by treatment-altered anatomy, posing a challenge to the emergency radiologist who needs to rapidly identify the presence of active hemorrhage and the potential source vessel. This retrospective review summarizes the clinical and imaging findings of 6 oropharyngeal and oral cavity squamous cell cancer (...

Evaluation of computed tomography perfusion and angiogram use in stroke evaluation for thrombectomy at a community emergency department setting
ConclusionsThis study helps to understand CT-P/A usage, especially in patients that fall outside of treatment criteria in the current thrombectomy literature. Results may have value to institutions interested in using CT-P/A as a diagnostic tool as well as institutions already incorporating it in stroke assessments. (Source: Emergency Radiology)

Split-bolus, single-phase contrast enhanced CT: a one-stop shop for invasive fungal sinusitis
AbstractContrast-enhanced magnetic resonance imaging is considered the imaging modality of choice for invasive fungal sinusitis (IFS); however, it is not feasible to perform emergency CEMRI especially in the setting of COVID-19. The CECT protocol for evaluation of suspected IFS can be modified by using split-bolus, single-phase CT as it provides an optimal soft tissue demonstration of sinonasal disease; extrasinus spread to orbit, and intracranial involvement along with simultaneous opacification of the internal carotid artery and cavernous sinus. The extent of bone erosion can also be well delineated on the multiplanar re...

Radiographic assessment of acute vs chronic vertebral compression fractures
ConclusionRadiographs are relatively insensitive in distinguishing between acute and chronic lumbar compression fractures but the presence of a subendplate cleft or subendplate density increases the likelihood that a given fracture is acute. (Source: Emergency Radiology)

Imaging patterns of thoracic injuries in survivors of intimate partner violence (IPV)
ConclusionAcute rib fractures with concomitant injuries to the head, neck, face, and extremities with an unclear mechanism of injury should prompt the radiologist to discuss the possibility of IPV with the ordering physician.Advances in knowledgeRecognizing common injuries to the thorax will prompt the radiologists to suspect IPV and discuss it with the clinicians.
