ABSTRACT

Purpose:

The COVID-19 pandemic caused by the coronavirus SARS-CoV-2 has resulted in a global health care crisis. The provision of CT imaging services by radiology departments for COVID-19 patients poses multiple challenges. Thus, the clinical indications and utility of thoracic CT, determined by whether it subsequently alters patient management, in COVID-19 patients is important to establish. Current literature is not well established specifically for the 'Delta' SARS-CoV-2 variant. Methods and Materials This is a single tertiary hospital centre retrospective review of all consecutive confirmed COVID-19 cases admitted during the peak of the 'Delta' variant wave in Australia who underwent a chest CT. Clinical indication for chest CT and patient management plan pre and post CT were ascertained. Result(s) During this period, 1403 patients were admitted with COVID-19 and 92 patients underwent CT of the thorax, with 18 patients scanned urgently. There were 73 CTPA, 14 CT Chest and 5 HRCT studies. 20 patients were in ICU at the time of scan. Regarding the clinical indications for thoracic CT, 72.8% of studies were to evaluate for pulmonary emboli, 16.2% for assessment of COVID-19 pneumonia complications, 5.4% for tuberculosis and 6.5% for other indications. 21 (23%) of these studies resulted in a change in management with 2 patients having a major change in management (thrombolysis, CT guided aspiration) whilst 19 had minor changes. Of 73 CTPA studies, 11 (15%) patients had evidence of pulmonary embolism. 6 patients underwent a second chest CT for diverse reasons. Conclusion(s) In conclusion, 6% of patients in the cohort of COVID- 19 patients admitted to our centre during the Delta variant wave of COVID-19 in NSW, Australia underwent a CT of the thorax. In 23% of these patients, chest CT resulted in a change in management. 72.8% of chest CT scans were for the evaluation of possible pulmonary emboli. CT was not used for diagnosis or follow-up of COVID-19 in any of our patients.
