Imaging review of sickle cell disease for the emergency radiologist
AbstractSickle cell disease (SCD), one of the most common inherited genetic syndromes in the USA, is characterized by recurring episodes of acute illness and progressive multisystem organ injury. Individuals with SCD frequently present to the emergency department for a spectrum of complications, such as vaso-occlusive crises, infection, cholecystitis, and stroke. Imaging correlates for most of these presentations exist, positioning the emergency radiologist to play a pivotal role in facilitating patient care. Using a systems-based approach, we describe the acute and chronic imaging manifestations of SCD that an emergency r...

Is point of care renal function testing reliable screening pre-IV contrast administration?
AbstractPurposeIntravenous iodinated contrast is a commonly used diagnostic aid to improve image quality on computed tomography. There exists a small risk of post-contrast acute kidney injury in patients receiving IV contrast. One of the biggest risk factors for developing PC-AKI is the presence of pre-existing renal dysfunction, making it important to measure the renal function prior to contrast administration. Point of care (POC) devices offer a quick estimation of renal function, potentially improving workflows in radiology departments.MethodTwo POC devices were evaluated, the Nova StatSensor and Abbott iSTAT.

Imaging primer for CT angiography in peripheral vascular trauma
AbstractThe use of computed tomography angiography (CTA) for the evaluation of peripheral vascular trauma has become increasingly prevalent in the past decade with the development of multidetector CT (MDCT) and multiple studies subsequently demonstrating high sensitivity, specificity, and diagnostic accuracy when compared with conventional angiography. Additional benefits of MDCT include the ability to rapidly acquire the images, perform multiplanar and 3D reconstructions, and assess the adjacent soft tissues and bones. Rapid intravenous injection of iodinated contrast material is required for optimal arterial enhancement....

Intraperitoneal focal fat infarction: the great mimicker in the acute setting
AbstractThe term intraperitoneal focal fat infarction (IFFI) includes various self-limiting clinical conditions that are caused by focal fatty tissue necrosis. Most of the cases of IFFI concern torsion or infarction of the greater omentum or the epiploic appendages. However, although rarely, perigastric ligaments can also undergo torsion also leading to fat infarction. IFFI clinically may mimic other pathologies, such as acute appendicitis or diverticulitis, making their clinical diagnosis a challenge. Ultrasound (US) and computed tomography (CT) have a high sensitivity and specificity for the diagnosis of IFFI excluding o...

Chest CT for triage during COVID-19 on the emergency department: myth or truth?
ConclusionChest CT, using the CO-RADS scoring system, is a sensitive and specific method that can aid in the diagnosis of COVID-19, especially if RT-PCR tests are scarce during an outbreak. 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)

A pictorial review of lung torsion using 3D CT cinematic rendering
AbstractLung torsion is the abnormal rotation of a lobe or lung around its bronchovascular pedicle. It most commonly occurs in the setting of pulmonary resection, though it has also been described after large-volume thoracentesis and video-assisted thoracic surgery, as well as spontaneously. Resulting ischemia can lead to infarction, making this an emergent diagnosis. As findings are often nonspecific, a high index of suspicion is required, especially in the postsurgical setting. 2D CT angiography findings are subtle and include direct signs of pedicle rotation on CT as well as indirect findings including loss of normal pa...
