The Indian Radiological and Imaging Association on Wednesday termed AIIMS Director, Dr Randeep Guleria's statements on use of CT scans in evaluation of Covid "misleading".
The association said that Guleria's warning that one CT scan is equal to 300-400 x-rays and CT scans cause cancer is "outdated and wrong".
It said the modern CT scanners use ultra low dose CT which has radiation comparable to only 5-10 x-rays.
It said with the advent of low dose CT techniques and advancement in the software, the dose is reduced to one-third to one-fourth and with ultra-low dose CT scan, it can be reduced to one-tenth.
