Avoid CT scans in mild Covid cases: AIIMS chief

May 03, 2021 19:11

AIIMS director Dr Randeep Guleria on Monday warned of the misuse of CT scans and biomarkers by patients having mild Covid-19 symptoms and said that the overuse of CT scans increases exposure to radiation that in turn escalates the risk of cancer.

"No point in conducting CT scans for mild cases; one may find patches in CT scan even if he/she is asymptomatic but may get cured easily 1 #CTScan = 300-400 Chest X-rays! With frequent CTs, risk of cancer in later life increases, for youngsters," Guleria warned, saying that the data by the international atomic energy commission for radiation protection and medicine have shown an increased risk of cancer in later life due to frequent CT scans, especially if done at a young age.

Guleria addressed the misuse of diagnosis, which he said is not required in case of mild symptoms. "A lot of people are getting CT scans done and deems it important to get CT scans done if their Covid tests turn out to be positive," he said. He cited a study that has shown patches in the CT scan of around 30-40 per cent of asymptomatic Covid-19 patients, which got cleared without any treatment. He used the study to make it clear that in case of mild infection, under home isolation with no problem or decline in saturation there is no use of a CT scan as some patches will appear.

India on Monday reported more than 3,68,000 fresh Covid-19 infections and 3417 fatalities in the last 24 hours, as per the Union health ministry data.
