India's teleradiology provider, TeleDiagnosys , is signing up new clients in southwest Europe and the U.S. over the past few months, according to the Pune, India-based firm.  The growth is being driven by increasing pressure to reduce costs and overcome shortages in the number of radiologists, according to TeleDiagnosys executives. Further supporting this growth is the rapid digitalization of hospitals and widespread reach of Internet is further driving the growth of this market, they said.
