Their letters do not directly address the design or findings of our study—that depending on the patient's clinical presentation, self-referral for diagnostic imaging examinations in office practice results in 1.7 to 7.7 times higher utilization and 1.6 to 6.2 times higher costs than when physicians refer their patients to radiologists.
