Association between pulmonary arterial obstruction index and right lateral ventricular wall thickness with in-hospital mortality in patients with acute pulmonary embolism
AbstractPurposeTo retrospectively assess the correlation between pulmonary arterial obstruction index (PAOI) and right lateral ventricular wall thickness with in-hospital mortality in patients with acute pulmonary embolism.MethodsCT angiography (CTA) of 55 consecutive patients (30 males; 25 females; mean age ± SD, 59 ± 11 years) with proven acute pulmonary embolism was investigated. PAOI was determined according to the Qanadli score on CTA. Right ventricular lateral wall thickness was also measured, and patients’ in-hospital mortality was recorded. The correlation between PAOI and mor...

MRI of myositis and other urgent muscle-related disorders
AbstractMyositis has many etiologies, and it can be encountered in the acute or chronic setting. Our goal is to increase the radiologist ’s knowledge of myositis and other urgent muscle disorders encountered in the emergent or urgent setting. We review the clinical presentation, the MRI appearance, and the complications that can be associated with these entities. Since myositis can affect multiple muscle compartments, we review how to differentiate the compartments of the appendicular skeletal in order to generate reports that relay important anatomic information to the treating physician. Given the poor sensitivity ...

A review of optimal evaluation and treatment of suspected esophageal food impaction
AbstractFluoroscopy-guided esophageal disimpaction of ingested food is a safe, effective, and cost-efficient alternative to endoscopically guided disimpaction. Patients with suspected esophageal impaction usually require fluoroscopy to confirm the diagnosis and determine the level of obstruction, which guides further management. Proximal esophageal food impactions at or near the cricopharyngeus muscle require an ENT intervention. Food impactions from the cervical esophagus to the aortic arch require a GI intervention. Obstructions distal to the aortic arch can usually be managed by the radiologist with a fluoroscopy-guided...

Gut wrenching: cases of missed gastrointestinal tumors and their mimics on computed tomography
AbstractComputed tomography (CT) of the abdomen and pelvis is one of the most common imaging studies ordered through the emergency department (ED). Because these studies are ordered for the detection of acute abnormalities and due to the relatively low incidence in patients presenting through the ED, gastrointestinal tumors are commonly missed. Moreover, many CT findings of malignant tumors overlap with benign entities, which can present a diagnostic challenge. This review article will describe the common CT findings of gastric, small bowel, colon, and appendiceal cancer as well as some of the common benign gastrointestina...

Intussusception in a child with COVID-19 in the USA
AbstractCOVID-19, caused by the novel coronavirus strain SARS-CoV-2 that emerged in late 2019, has resulted in a global pandemic. COVID-19 was initially believed to occur less frequently in children with relatively mild disease. However, severe disease and varied presentations have been reported in infected children, one of such being intussusception. There have only been three reported cases of intussusception in the pediatric population infected with COVID-19. In this paper, we will discuss the management and treatment of a novel fourth case of COVID-19-associated intussusception. This case is the first reported in the U...

AbstractSuperior soft-tissue contrast and high sensitivity of magnetic resonance imaging (MRI) for detecting and characterizing disease may provide an expanded role in acute abdominal and pelvic imaging.

Traumatic abdominal wall injuries —a primer for radiologists
AbstractTraumatic abdominal wall injuries encompass a broad clinical and radiological spectrum and are identified in approximately 9% of blunt trauma patients. The most severe form of abdominal wall injury —a traumatic abdominal wall hernia—is seen in less than 1.5% of blunt abdominal trauma patients. However, the incidence of concurrent intra-abdominal injuries in these patients is high and can result in significant morbidity and mortality. Although the diagnosis of abdominal wall injuries is typ ically straight forward on CT, associated injuries may distract the interpreting radiologist in more subtle cases. ...

Patients with falls from standing height and head or neck injury may not require body CT in the absence of signs or symptoms of body injury
ConclusionPatients with falls from standing height and known head/neck injury had a low rate of clinically impactful body injury. None of the studied variables were associated with increased risk of body injury in this patient population. The low rate of clinically impactful body injury and the lack of any mortality, procedure, or transfusion resulting from body injury suggest that body CT may not be necessary in patients with head/neck injury in the absence of clinical or radiographic evidence of body injury.

Combining a predictive machine learning model could further improve the accuracy of diagnostic chest CT for COVID-19. Further candidate predictors should be analyzed to improve our model. However, RT-PCR should remain the primary standard of testing as up to 9% of RT-PCR positive patients are not diagnosed by chest CT or our machine learning model. (Source: Emergency Radiology)
