1. Background

Early studies in China suggested that chest CT may be a more reliable, practical, and rapid method to diagnose and assess COVID-19 compared to RT-PCR, especially in the epidemic era.In contrast, recent evidence supports that outside of China, where there is a low-prevalence of COVID-19 (1-22.9%), chest CT screening of patients with suspected disease had low positive predictive value (1.5-30.7%). Although chest CT is advised not to be used as a screening tool for detecting COVID 19, CT manifestations may associate with the prognosis of the infection.

In general, radiographers/radiological technologists must be prepared and equipped to perform CT examinations with caution during the pandemic and nowadays, when chest CT is indicated for the progression of the infectious disease.

The ISRRT is dedicated in protecting radiographers/radiological technologists who practice at the frontline of healthcare and has developed a COVID 19 Response Document incorporating the appropriate and safe use of Medical imaging and Radiation Therapy with infection control measures for every modality.

The measures,

  • have been developed using the general guidelines from the World Health Organization, the Centers for Disease Control and Prevention as well as the European Centre for Disease Prevention and Control
  • are based on the “how”, “where” and “when” radiographers/radiological technologists should perform medical imaging and therapy procedures during the period of COVID 19
  • should be applied accordingly by radiographers / radiological technologists in addition to standard radiation protection procedures
