Chest-CT mimics of COVID-19 pneumonia —a review article
AbstractCoronavirus disease 2019 (COVID-19) emerged in early December 2019 in China, as an acute lower respiratory tract infection and spread rapidly worldwide being declared a pandemic in March 2020. Chest-computed tomography (CT) has been utilized in different clinical settings of COVID-19 patients; however, COVID-19 imaging appearance is highly variable and nonspecific. Indeed, many pulmonary infections and non-infectious diseases can show similar CT findings and mimic COVID-19 pneumonia. In this review, we discuss clinical conditions that share a similar imaging appearance with COVID-19 pneumonia, in order to identify ...

Automated radiomic analysis of CT images to predict likelihood of spontaneous passage of symptomatic renal stones
ConclusionThe semi-automated radiomic analysis of urinary stones shows similar accuracy compared with manual measurements for predicting urinary stone passage. Further studies are needed to predict clinical impacts of reporting the likelihood of urinary stone passage and improving inter-observer variation using automatic radiomic analysis software.

Diagnostic utility of computed tomography in patients presenting to the emergency department with unintended weight loss
AbstractPurposeUnintended weight loss (UWL) is a common presenting symptom in the emergency department (ED) with several etiologies. Our study looks to evaluate the diagnostic utility of computed tomography (CT) in the evaluation of UWL in the ED.MethodsWe identified all patients who underwent CT of the chest, abdomen, or pelvis in the ED at our institution for the diagnosis of UWL from 2004 to 2020 and retrospectively reviewed their clinical history and imaging. CT findings were organized into 4 types: (1) definite cause for UWL identified, (2) possible findings for UWL, (3) incidental findings unrelated to UWL, and (4) n...

ConclusionsThe cost of negative CSMRI following a negative CSCT for cervical spine clearance in trauma patients without other significant injury is substantial. The length of time that trauma patients remain in observation in the cervical collar prior to the finalized MRI exam is not only distressing to the patient but also adds costs to health care systems in both time and resources.

CT imaging of extraglottic airway device —pictorial review
AbstractCompared to intubation with a cuffed endotracheal tube, extraglottic airway devices (EGDs), such as laryngeal mask airways, are considered less definitive ventilation conduit devices and are therefore often exchanged via endotracheal intubation (ETI) prior to obtaining CT images. With more widespread use and growing comfort among providers, reports have now described use of EGDs for up to 24 h including cases for which clinicians obtained CT scans with an EGD in situ. The term EGD encompasses a wide variety of devices with more complex structure and CT appearance compared to ETI. All EGDs are typically placed witho...

Simplifying the complicated heel —an emergency imaging approach to calcaneal fractures
AbstractThe calcaneum is the most inferior and largest tarsal bone and supports the axial load of the weight of the body. Calcaneal fractures formulate 60% of the tarsal fractures and are frequently encountered in almost all trauma centres. It becomes imperative to understand and report calcaneal fractures in a structured fashion for better clinical and treatment outcomes for the patients. Radiologists should be well acquainted with calcaneal fractures and their various classifications and should develop an algorithmic approach for diagnosing and reporting heel fractures.

The likely association between wandering spleen and absent left kidney
AbstractWandering spleen is a cause of acute surgical abdomen with serious consequences. It arises from an absence or weakness of the supporting suspensory splenic ligaments. There is often a delayed diagnosis due to its non-specific clinical presentation. This leads to stalled acquisition of confirmatory diagnostic imaging with resultant increased morbidity and mortality. Congenital or acquired absence of the left kidney results in loss of the splenorenal ligament, a key ligament to maintain normal splenic position in the abdomen. Two patients, one with OHVIRA (obstructed hemivagina ipsilateral renal anomaly) syndrome and...
