PETNET Solutions, Inc. has signed a five-year deal with the Irving-based group purchasing organization Novation to supply its member hospitals and clinics with PET radiopharmaceuticals. The agreement covers oncology, cardiology and neurology agents. A few weeks ago Novation also announced a similar deal with IBA Molecular, which also runs PET radiopharmacies. The Knoxville, Tennessee-based PETNET is the largest FDA-registered network of radiopharmacies in the world, according to a Siemens’ press release. Novation services approximately 65,000 members of VHA Inc., UHC, and Provista LLC.
