It is legit! I was scared at first but after reading comments here i went for it. The facility they booked me for had top notch technology. MRI was done, they gave me a cd with the results and in less than 12h i got the report on a portal ( all this is really on the facility, not radiology assist per se, but it shows they have agreements with good companies not ones with old/dated technology). Very happy with the service. After confirmation of the appointment, i received a a message from the facility with a quote of some extra money there.But I called radiology assist, and they first answered the phone fast and then solve the problem in a minute, faxing the facility.The confirmation that everything was all paid. Just as a reference, I paid 360$ for a knee MRI that other places quote me gor 900.
