Medical Scans are reviewed abroad. This practice started in Dentistry in the 90s/early 2000s but expanded to Radiological scans as well. At this point most CT, MRI, and XRay scans in the US have a first pass analysis done by doctors in India+Pakistan.
Medical billing has also been offshored to India+Pakistan btw
In general, a lot of back office Dental+Medical functions were outsourced in the 2000s+2010s.
They've already done it with outsourcing; a large chunk of what used to be done entirely in-house has been contracted out to remote overseas doctors.
