What are all the different types of noises that an MRI makes when you’re getting a scan? And why is it different noises every few minutes?
In: Technology
I was told the first scans are low-res and let the shot be setup or aimed correctly. Then when all’s good, hit the higher res scans. There’s differences in power, frequencies, etc. for low- vs. high-res scanning, and the machine sounds different when these variables change.
Source: had an MRI, asked the technician.
