There was a similar discussion just over a year ago [1], and I was shocked then to find out that India offers full-body MRIs for probably 20% of the price.
Once amortized, The cost (outside of normal cryogenics resupply) is mainly the one of the personnel running it so a factor of 1/5 doesn't seem too surprising to me between India and US. I'm sure the overcharge from the hospital or clinic is not negligible either.
