Diagnostic imaging companies - each of the big ones (Siemens, GE, Philips) all offer in-house financing on very favorable terms for MRI, CT, etc., that they specifically advertise to physicians. They also all offer specialist consulting help to facilitate you getting a CoN (Certificate of Need) for your facility. Hell, they also will help you find other physicians in your area who'd like to go in with you on setting up a DI facility, and they will assist with spinning up the practice.
We then find that physicians who own a DI practice (or a share in one) refer their patients to diagnostic imaging at rates several standard deviations above other physicians and at rates that are "statistically improbable" when correlated to underlying ICD-10 diagnostic codes.
