CT involvement score can help in evaluation of the severity and extent of the disease.
Hurt B, Kligerman S, et al. Deep Learning Localization of Pneumonia 2019 Coronavirus (COVID-19) Outbreak. J Thorac Imaging. April 2020 

Ziel: Study describes a deep learning approach to augment radiographs with a color probability overlay to improve the diagnosis of pneumonia.

Ergebnis: Algorithm predicted and consistently localized areas of pneumonia with increasing likelihood, as the subtle airspace opacities increased over time. It is worth noting that each radiograph was analyzed by the algorithm independently without awareness of the time course or relationship of previous films. In each case, the predicted probability map correctly localizes the findings and assigns likelihoods that mirror the severity of the imaging findings.
Raptis C, Hammer M et al. Chest CT and Coronavirus Disease (COVID-19): A Critical Review of the Literature to Date. AJR April 2020

Ziel: The purpose of this article is to critically review some of the most frequently cited studies on the use of CT for detecting COVID-19.

Ergebnis: To date, the radiology literature on COVID-19 has consisted of limited retrospective studies that do not substantiate the use of CT as a diagnostic test for COVID-19. Research describing CT features of COVID-19 has consisted mostly of retrospective reviews and case studies, and it should be "considered low quality" according to the authors.
Weinstock et al. Chest X-Ray Findings in 636 Ambulatory Patients with COVID-19 Presenting to an Urgent Care Center: A Normal Chest X-Ray Is no Guarantee. JUCM April 2020

Ting DSW, Carin L et al. Digital technology and COVID-19. Nature Medicine March 2020

Ziel: To explore the potential application of four inter-related digital technologies (the IoT, big-data analytics, AI and blockchain) to augmenting two traditional publichealth strategies for tackling COVID-19: (1) monitoring, surveillance, detection and prevention of COVID-19; and (2) mitigation of the impact to healthcare
indirectly related to COVID-19

Ergebnis: There is a wide range of digital technology that can be used to augment and enhance these public-health strategies. The immediate use and  successful application of digital technology to tackle a major, global public-health challenge in 2020 will probably increase the public and governmental acceptance of such technologies for other areas of healthcare, including chronic disease in the future.

Ergebnis: This report summarizes evidence for thromboembolic disease, potential diagnostic and preventive actions as well as recommendations for patients with COVID-19 infection.
Nair et al., A British Society of Thoracic Imaging statement: considerations in designing local imaging diagnostic algorithms for the COVID-19 pandemic. Clinical Radiology March 2020

: They considered how a CXR would also fit into diagnostic algorithms, and in particular, how the use of CT would alter management in settings where a CXR
was or was not available.

Ergebnis: A high pre-test probability is assumed for symptomatic cases, based on one or more of: clinical presentation (Pyrexia of 37.8); acute onset persistent
cough, hoarseness, nasal discharge or congestion, shortness of breath, sore throat, wheezing, sneezing; and compatible laboratory abnormalities (relative
lymphopenia, elevated C-reactive protein [CRP] 
Borghesi et al., Radiographic severity index in COVID‑19 pneumonia: relationship to age and sex in 783 Italian patients. La radiologia medica May 2020

Ziel: To improve the risk stratification of patients infected with SARS-CoV-2, an experimental chest Xray (CXR) scoring system for quantifying lung abnormalities 
was introduced in our Diagnostic Imaging Department.

Patienten: 783

Ergebnis: The CXR score was significantly higher in males than in females only in groups aged 50 to 79 years. A significant correlation was observed between the CXR score and age in both males and females. Males aged 50 years or older and females aged 80 years or older with coronavirus disease 2019 showed the highest CXR score (median ≥ 8). In conclusion, males aged 50 years or older and females aged 80 years or older showed the highest risk of developing severe lung disease. Our results may help to identify the highest-risk patients and those who require specific treatment strategies. 
Jones et al., COVID-19 and Kawasaki Disease: Novel Virus and Novel Case. Hospital Pediatrics April 2020

Ziel: This study looked at a total of 2143 patients, 1412 of whom had suspected but unconfirmed COVID-19 infection, but there was little description of co-incidence of other clinical conditions, and no cases reported of concurrent Kawasaki disease (KD). Authors describe the case of a pediatric patient diagnosed and treated for classic KD in the setting of confirmed COVID-19 infection, published with parental permission.

Patienten: 2143

Ergebnis: This is the first described case of KD with concurrent COVID-19 infection. KD is an acute vasculitis of childhood and the leading cause of acquired heart disease in children in developed countries, with 50% of cases occurring in those <2 years of age, and 80% in those <5 years of age.4 The diagnosis of “classic” KD is considered in patients presenting with fever for 5 days together with at least 4 out of 5 clinical criteria in the absence of an alternate diagnosis.
Although the clinical significance of our patient’s positive COVID-19 testing in the setting of her KD is not clear, her testing for COVID-19 appears accurate.
This case report may serve as a useful reference to other clinicians caring for pediatric patients affected by COVID-19 as understanding of the clinical presentation patterns continue to evolve. Further description of the clinical course of pediatric patients diagnosed with COVID-19 remains necessary, particularly regarding the potential association with KD.
