How accurate is chest imaging for diagnosing COVID-19?Why is this question important?People with suspected COVID-19 need to know quickly whether they are infected, so that they can self-isolate, receive treatment, and inform close contacts. Currently, formal diagnosis of COVID-19 infection requires laboratory analysis of blood or nose and throat samples. The laboratory test, called RT-PCR, requires specialist equipment and takes at least 24 hours to produce a result. Further, RT-PCR is not completely accurate and a second RT-PCR or a different test may be required to confirm the diagnosis.COVID-19 is a respiratory infectio...

Use of lung ultrasound in COVID-19: comparison with ultra-high-resolution computed tomography among 29 patients at "D. Cotugno" hospital, Naples, Italy. Infez Med. 2020 Sep 01;28(3):346-350 Authors: Iodice V, Pisaturo M, Fusco FM, Tambaro O, Parrella G, Di Flumeri G, Viglietti R, Pisapia R, Palmiero G, Bignardi E, Coppola M, Rescigno C, Sangiovanni V Abstract Ultra-High-Resolution Computed Tomography (U-HR-CT) is the reference imaging technique for pneumonia in the new coronavirus disease (COVID-19). Pulmonary Ultrasound (LUS) could be a valid diagnostic alternative for the imaging of COVID-1...

Abstract BACKGROUND: Point-of-care ultrasound (POCUS) of the lung in patients with COVID-19 plays a key role in the emergency room and intensive care unit. Lung ultrasound is able to depict typical pulmonary findings of COVID-19 and is therefore suitable for diagnosis and follow-up of these patients. CLINICAL/METHODOLOGICAL ISSUE: Lung ultrasound in COVID-19 patients in the emergency room and intensive care unit. STANDARD RADIOLOGICAL METHODS: Computed tomography (low-dose CT) and X‑ray of the lung. METHODOLOGICAL INNOVATIONS: Lung ultrasound in COVID-19 patients. RECOMMENDATIO...

AbstractThe association between coronavirus disease 2019 (COVID-19) pneumonia and venous thrombotic disorders is still unclear. We assessed the association between COVID-19 infection-related pneumonia and proximal deep-vein thrombosis (DVT) in a cohort of patients admitted to our hospital during the European outbreak in the front line of Cremona, Lombardy. In a single-center cross-sectional study, all patients hospitalized for more than 5  days in Internal Medicine Department with confirmed COVID-19 pneumonia received 2-point compressive ultrasound assessment (CUS) of the leg vein system during a single day. Ninety-fo...

Abstract CLINICAL ISSUE: The COVID 19 pandemic led to a profound adaptation of the German healthcare system in preparation of a massive increase of SARS-CoV-2-associated diseases. While general practitioners care for COVID patients who are less severely ill, hospitals are focused on the care of severely ill COVID-19 patients. STANDARD TREATMENT: The role of emergency medicine (EM) is to rapidly detect the virus, to classify disease severity, and to initiate therapy. In addition, the flow of patients into the hospital must be directed in such a way that optimal care is provided without risk of i...

AbstractCoronavirus disease of 2019 (COVID-19) is a highly infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has rapidly spread to a global pandemic in March 2020. This emergency condition has been putting a severe strain on healthcare systems worldwide, and a prompt, dynamic response is instrumental in its management. While a definite diagnosis is based on microbiological evidence, the relationship between lung ultrasound (LU) and high-resolution computed tomography (HRCT) in the diagnosis and management of COVID-19 is less clear. Lung ultrasound is a point-of-care imaging to...

ConclusionIt seems unnecessary to perform chest imaging in children to diagnose COVID-19. Chest radiography can be used in symptomatic children to assess airway infection or pneumonia. CT should be reserved for when there is clinical concern to assess for possible complications, especially in children with coexisting medical conditions.

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) disease (COVID-19) is characterized by a severe pneumonia and/or acute respiratory distress syndrome (ARDS) in about 20% of infected patients. Computed tomography (CT) is the routine imaging technique for diagnosis and monitoring of COVID-19 pneumonia. Chest CT has high sensitivity for diagnosis of COVID-19, but is not universally available, requires infected or unstable patient to be moved to the Radiology unit with potential exposure of several people, CT room needs proper sanification after use, and is underutilized in children and pregnant women for radioexposition concerns.

CONCLUSIONS: Our study suggested that COVID-19 pneumonia was associated with hypercoagulable state. However, the rate of VTE in COVID-19 pneumonia patients was not significantly higher than that in CAP patients. PMID: 32628040 [PubMed - as supplied by publisher]

AbstractIn December 2019, a novel coronavirus (SARS-Cov-2) was first reported in Wuhan, China, and rapidly spread around the world, leading to an international emerging public health emergency. As reported from Chinese experiences, approximately 20% of patients had a severe course, requiring intensive care, with an overall case fatality rate of 2.3%. In diagnosis, chest computed tomography most commonly showed ground-glass opacity with or without consolidative patterns.Herein, we report a case of a patient affected by COVID-19 pneumonia referred in the emergency department of our institution on April 4, 2020, with peculiar...
