A new high-tech imaging center is opening in Southdale Medical Center in Edina, MN. Called Suburban Imaging, the joint venture involves two large radiology groups, the state’s third-largest hospital and clinic group, Fairview Health Services; and 21 physician groups in the area. Its opening is likely to reignite a debate on whether Minnesota has too many diagnostic imaging facilities and encourages doctors to order unnecessary procedures and pushing up medical costs. It’s also likely to raise the question of whether doctors should refer patients to a facility in which they have a financial stake.
