Finally someone figured out the truth. - That there is only one company in India that provides outsourcing radiology services to the US
The other truths are - Companies within the US with branches in Switzerland, Hawaii and Australia do much more outsourcing - That there has to be a significant, usually family-based reason for someone to give up a 350K USD job to come back to India to do teleradiology - That there are some who run sweat-shops and pay 10-20USD for CT scan and MRI reports, but that's really illegal from the US perspective, though not from the Indian perspective - but these are few and far between as well
In short, just like medical tourism, the hype is much more exciting.
A presentation at the recent ARRS, written up in Diagnostic Imaging, talks about the cost-effectiveness of cardiac CT angiography (CTA) vis-a-vis conventional catheter angiography (CCA). This entirely depends on the rate of normal CCAs in a cath lab. Since a CCA costs around 2800USD, for a 10% normal rate, a CTA is cost-effective at 270USD, but with a 30% normal rate, it becomes cost-effective even at 810USD.
In India, typically, a CTA costs Rs. 10000 (approx. 222USD) and a CCA around Rs. 15,000 (333USD). The difference isn't much, meaning that from a public health perspective, CTA does not become all that cost-effective. From a patient's perspective, in a low-risk or medium-risk environment however, it is 50% cheaper and avoids all the other complications that may occur with CCA, though with a slightly higher radiation dose.
