As a diagnostic imaging manager, your job is to oversee the delivery of radiologic services, such as MRI scans. This is not a medical role, and you may have little or no direct interaction with patients. Instead, diagnostic managers have duties and responsibilities like preparing cost estimates, negotiating with outside vendors, training staff members, and managing payroll. Diagnostic imaging managers also help ensure that all procedures and policies at a given office meet accreditation standards. Some details of this job depend on the size of your clinic and the number of subordinates you oversee. Diagnostic imaging managers usually work regular hours, but you may work unusual shifts if your facility offers 24/7 services.
