Radiology imaging orders database

This radiology imaging orders ER diagram separates a clinician’s imaging request from the completed study and its clinical interpretation. The order identifies the patient, requesting provider, modality, and priority. When imaging is performed, a study with a unique accession number fulfills that order and contains one or more series. A report records the radiologist’s interpretation and signing status.
