Citigroup said General Electric (GE) exited the radiation oncology space in the 1990's and since then has had virtually no interest in getting into the treatment side of healthcare versus diagnostics. Further, the firm's analyst said Varian (VAR) is in the midst of spinning off their imaging business, and in theory, would make Varian a much more attractive target for General Electric. However, Citi said a takeover of Varian before the spin closing in December would make no sense by General Electric and reduces the firm's belief in today's speculation.
