COVID Can MRI detect COVID infection in lungs?

AI Thread Summary
The discussion highlights concerns regarding the reliability of RT-PCR tests during the current pandemic wave, with reports of false negatives leading to doctors recommending CT scans for symptomatic patients. These scans often reveal significant lung damage indicative of COVID-19. However, the Director of AIIMS cautioned against the overuse of CT scans, noting their high radiation exposure and potential long-term cancer risks, particularly in younger individuals. The conversation also explores the possibility of using MRI as an alternative for lung infection detection, citing its different technology and potentially lower long-term risks, despite its higher cost compared to CT scans.

During this second wave of pandemic in our country, there have been several cases where the RT-PCR test is yielding false negatives. Many patients are being advised CT scans by doctors if the RT-PCR is negative, but the patient still shows symptoms of COVID. In many cases, this has given good results - doctors have found that the patient's lungs are completely covered by white patches, which are indicative of the virus residing and multiplying there.

Yesterday, the Director of the All India Institute of Medical Sciences (AIIMS) said, as per a news article, that CT is being "misused" during this period, adding that one CT is equivalent to 300-400 chest X-rays, and in younger people, too many CT scans throughout their lives may lead to cancer in later life.

Fine, I understand that. On the other hand, MRI, which uses an entirely different technology based on NMR, probably has lesser long-term side effects.

Can MRI be used to detect COVID infection in the lungs instead of CT or simple chest X-ray?

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
