CT chest analysis of 2019 novel coronavirus pneumonia: An Indian perspective
Conclusions: COVID-19 pneumonia showed multifocal predominantly subpleural basal posteriorly located GGOs and/or consolidations which were predominantly well defined. “Crazy paving” was prevailing in the intermediate stage while early traction bronchiectasis among the patients presented later in the course of illness.

Back to the basics: Study of portable chest radiographic findings in 116 COVID-19 positive patients in an Indian tertiary care hospital
Conclusions: Significant number of COVID-19 patients were asymptomatic. Over 1/3rd of patients showed radiographic abnormalities. Symptomatic patients were more likely to show radiographic findings than asymptomatic patients. If radiographs identify pneumonia in appropriate clinical setting, CT can be avoided. Common radiographic abnormalities among COVID 19 patients were bilateral/unilateral, patchy, multifocal, ground glass opacity or consolidation in peripheral and middle/lower zone distribution.

Demographic and clinico-radiological profile on High-Resolution Computerized Tomography (HRCT) thorax in mild or asymptomatic clinically suspected COVID-19 patients in high-endemicity area of India & #8212;Can HRCT be the first screening tool ? & #8212;The DECRYPTION study
Conclusion: Chest HRCT picked 48.46% positive cases in mildly symptomatic and asymptomatic patients of which 3.22% had severe involvement (>17). Being a noninvasive, rapid, sensitive, low risk of cross infection with high reproducibility, chest CT is worth evaluating as screening modality even in asymptomatic and mildly symptomatic clinically suspected COVID-19.

Where have all the diseases gone during the COVID-19 pandemic ?
This article focuses on a marked drop in volumes in the lockdown period during the COVID-19 pandemic across all modalities X-ray, sonography, CT scan and MRI scans and compares the volumes of data between a private and public hospital in Mumbai. This trend has been witnessed globally also. Even with easing of lockdown this has not reflected in an increase in numbers. Imaging volumes of a 1900-bed public hospital and a 220-bed private hospital in Mumbai were collated for all modalities, i.e., X-ray, sonography, CT and MRI for the months January, February 2020- Prelockdown, March 2020 Peri-lockdown, April, May 2020- Lockdown...

Pattern recognition of high-resolution computer tomography (HRCT) chest to guide clinical management in patients with mild to moderate COVID-19
Conclusion: HRCT chest and assessment of lung patterns can help triage patients to home quarantine and hospital admission. Early initiation of steroids and anticoagulants based on lung patterns can prevent progression to more severe stages and aid early recovery. HRCT can play a major role to triage and guide management especially as RT PCR testing and results are delayed for the benefit of patients and in a social cause to decrease the spread of the virus (Source: Indian Journal of Radiology and Imaging)

Retrospective analysis of chest HRCT findings in coronavirus disease pandemic (COVID-19)- An early experience
Conclusions: Typical peripheral subpleural distributions of GGO's with bilateral asymmetrical lung involvement are characteristic features of COVID19 pneumonia. Chest HRCT can be a very useful and standard imaging method to assess the severity and progression of the disease and thereby optimizing the management of patients. With increasing case load all over the world HRCT can be used as a one stop radiological investigation for the diagnosis and prognosis of corona virus disease.

Role of portable chest radiography in management of COVID-19: Experience of 422 patients from a tertiary care center in India
Conclusion: The presence of multifocal air-space opacities with bilateral, peripheral distribution on chest radiograph is highly suggestive of COVID-19 pneumonia in this pandemic setting.Portable chest radiography is a widely available and quicktool for estimating the evolution and assessing the severity of lung involvement of COVID-19 pneumonia in hospitalized symptomatic patients.

Does CT help in reducing RT-PCR false negative rate for COVID-19 ?
Conclusion: There was a communality of CT findings regardless of RT-PCR status. In a pandemic setting ground glass densities in a subpleural, posterior and basal distribution are indicative of COVID 19. Thus CT chest in conjunction to RT PCR augments the diagnosis of COVID 19 pneumonia; utilization of CT chest may just be the missing link in closing this pandemic.

The value of AI based CT severity scoring system in triage of patients with Covid-19 pneumonia as regards oxygen requirement and place of admission
Conclusions: CT severity scoring using an automated deep learning software programme is a boon for determining oxygen requirement and triage. As the score increases, the chances of requirement of higher oxygen and intubation increase. All the three scoring systems are predictive of oxygen requirement.
