CR negative cases. Therefore, a combination of both CT and RT-PCR for future follow-up, management and medical surveillance is recommended considering the false-positive results of chest CT in the diagnosis of COVID-19 pneumonia.

High diagnostic accuracy of chest CT findings with typical and relatively atypical CT manifestations of COVID-19 leads to a low rate of missed diagnosis. Normal chest CT can be found in RT-PCR positive COVID-19 cases, and typical CT manifestations can be found in RT-PCR negative cases. Therefore, a combination of both CT and RT-PCR for future follow-up, management and medical surveillance is recommended considering the false-positive results of chest CT in the diagnosis of COVID-19 pneumonia.

Since its outbreak, the COVID-19 pneumonia pandemic is rapidly spreading across India; although computed tomography of chest (CT chest) is not recommended as a screening tool, there is a rapid surge in the CT chest performed in suspected cases. We should be aware of the imaging features among the Indian population.

To analyze the CT chest features in Indian COVID-19 patients.

Retrospective study.

CT chest of 31 polymerase chain reaction (PCR) verified patients of COVID-19 was assessed for ground-glass opacities (GGO), consolidations, bronchiectasis, pleural effusions, vascular enlargement, crazy paving, and reverse halo sign.

The data was analyzed in Microsoft Excel 2019.

Only one patient showed a normal scan. Multilobar involvements with parenchymal abnormalities were seen in all the patients with bilateral involvement in 74.1%. 42.5% of the lung parenchymal abnormalities were pure GGOs, while 41.6% had GGOs mixed with consolidation. Peripheral and posterior lung field involvement was seen in 70.ermediate stage while early traction bronchiectasis among the patients presented later in the course of illness.

Paucity of literature of portable CXR findings in COVID-19.

Evaluate radiographic findings in COVID-19 patients and calculate sensitivity of radiographs with RT-PCR as gold standard.

Total 116 COVID-19 patients underwent portable CXR between April-June, 2020. Two radiologists reviewed radiographs with respect to laterality, craniocaudal, mediolateral distribution, shape, density, unifocality/multifocality and number of lung zones. Sensitivity of radiography was calculated with RT-PCR as gold standard.

IBM SPSS Statistics Subscription software (IBM, New York, USA).

Many patients 67.2% (78/116) were asymptomatic. Cough (21.5%, 25/116) and fever (17.6%, 20/116) were the most frequent symptoms. 36.2% (42/116) patients revealed COVID-19 pneumonia-like abnormalities on CXR. Sensitivity of CXR with RT-PCR as gold standard was 36.2% (CI Confidence interval = 27.46% - 44.95%). More patients in symptomatic group (68.4%, 26/38) had abnormal CXR compared to asymptomatic group (20.5%, 16/78) [

< 0.0001]. GS-441524 Rato 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.

In this study, we aim to evaluate the perception and practice of IPC measures by Radiologists during pre-COVID and present COVID times, while conducting a thorough review of current concepts and literature, to provide a standard operating procedure (SOP) for radiology operations.

This study was conducted by Department of Radiodiagnosis and Imaging, Kasturba Medical College, MAHE, Mangalore. After obtaining approval from the institutional ethics committee, and other required permissions, the Google form questionnaire was sent to 350 Radiologists via email and text during the period of May 2020. Data was collected by time-based sampling in the period of fifteen days during the end of the total lockdown time.

54% (

= 152) reported never attending a training session on (Infection Prevention & Control) IPC prior to the COVID-19 outbreak. The perception regarding IPC were found to be good among radiologists as majority of the respondents were correctly able to answer questions regarding IPC. 86% (

= 152) of the respondents believed that their knowledge on IPC has improved during the COVID-19 pandemic. However, it was revealed that majority of the respondents only started to practice appropriate contact and droplet / procedural precautions only after the COVID-19 outbreak.

The present COVID-19 scenario coupled with the lack of knowledge and training regarding IPC amongst radiologists evident from the results of our survey, highlights the need for proper training and establishing standard operating procedures and best practices in IPC pertinent to modern radiology practice.

As a response to the CoronaVirus Disease 2019 (COVID-19) pandemic, India announced a nation-wide lockdown effective from March 25, 2020. Recent media reports and published studies from Western countries indicate a decrease in patients presenting to hospitals with stroke, acute coronary syndromes, and other emergencies.

The purpose of this study was to assess the impact of the lockdown on the number of patients undergoing Computed Tomography (CT) in a public tertiary care hospital in India, and thus indirectly assess the effect of the lockdown on medical conditions other than COVID-19.

Retrospective observational study.

Analysis of the CT reports from the hospital's PACS for the first three months of lockdown was performed and compared with those of the month prior to the imposition of the lockdown.

Frequency tables and percentages were calculated.

There was a 70% decrease in the number of total CTs in the first three months of lockdown compared to the month prior to lockdown. There was a decrease in CTs performed for various conditions such as tuberculosis follow up (decreased by 98%), brain infarcts, nontraumatic intracranial hemorrhage (decreased by 40%), and baseline CTs for neoplasms (decreased by 73%).
