Clinical

The combined date and time at which an imaging examination was performed, recorded as a single timestamp in the radiology information system or PACS. Used for precise sequencing of imaging events, workflow analysis, turnaround time measurement, and correlation with clinical documentation.

The Drug Enforcement Administration registration number associated with a prescribing clinician linked to an imaging study, typically relevant when sedation or contrast premedication is ordered. Used to validate prescriber credentials and ensure regulatory compliance in imaging workflows involving controlled substances.

The date of death for the patient associated with an imaging study. Used in radiology and clinical data systems to flag deceased patient records, halt pending imaging orders, support mortality reporting, and ensure appropriate handling of posthumous imaging data in downstream analytics.

The calendar date on which an imaging study record was marked as deleted in the radiology information system or PACS. Used for audit trail maintenance, data governance, and compliance purposes, preserving a historical record of when studies were removed without permanent destruction of the metadata.

A flag indicating whether an imaging study record has been logically removed from active use in the radiology information system or PACS. Used to filter deleted studies from clinical workflows and reporting while retaining the record for audit, compliance, and historical data reconciliation purposes.

A human-readable text description of an imaging examination, typically derived from the order or DICOM header, such as CT Chest with Contrast or MRI Brain without and with Contrast. Used in radiology workflows to identify study type, guide technologist protocols, and populate imaging reports and patient records.

Supplementary information captured about an imaging examination beyond standard structured fields, including acquisition parameters, special instructions, clinical indications, or procedure notes. Used in radiology information systems to provide technologists and radiologists with additional context needed for accurate image acquisition and interpretation.

The date on which the patient associated with an imaging study was discharged from an inpatient or observation encounter. Used in radiology and hospital information systems to correlate imaging timing with hospitalization, support length-of-stay analysis, and reconcile inpatient imaging orders with clinical discharge workflows.

The target date by which an imaging study is expected to be completed, interpreted, or reported. Used in radiology workflow management systems to prioritize pending studies, monitor turnaround time compliance, and trigger escalation alerts when imaging examinations approach or exceed expected completion deadlines.

The total elapsed time from the start to the completion of an imaging examination, typically measured in minutes. Used in radiology operations and scheduling systems to assess scanner utilization, optimize appointment slot planning, benchmark modality performance, and support staffing and resource allocation decisions.

The electronic mail address associated with the ordering clinician, patient, or contact linked to an imaging study. Used in radiology information systems to facilitate result notifications, study sharing, report delivery, and communication with referring providers or patients regarding imaging findings and follow-up recommendations.

A flag designating an imaging study as emergent or stat, requiring immediate prioritization in the radiology workflow. Used in PACS and radiology information systems to route urgent studies to available radiologists, trigger escalation protocols, and ensure critical findings are communicated within clinically required timeframes.

The date on which an imaging examination was completed or the associated imaging study period concluded. Used in radiology information systems to calculate study duration, measure workflow turnaround times, close open orders, and support reporting on imaging throughput and departmental operational performance.

The timestamp recording when a diagnostic imaging examination was completed, captured in DICOM or RIS systems. Used to calculate total study duration, technologist workload metrics, and radiology workflow efficiency reporting across imaging departments.

The username or system identifier of the staff member who entered the imaging study record into the radiology information system (RIS) or PACS. Used for audit trail tracking, data quality accountability, and workflow management in diagnostic imaging departments.

The patient's self-reported or assigned ethnic background associated with an imaging study record. Used to support demographic analysis, health equity reporting, and population-based research on imaging utilization patterns across diverse patient populations.

The date after which an imaging study order, authorization, or associated protocol is no longer considered valid for scheduling or execution. Used to enforce insurance authorization windows, manage standing imaging orders, and ensure regulatory compliance in radiology workflows.

A reference identifier assigned by an external system, such as a referring hospital, health information exchange, or third-party imaging center, that links an imaging study to records outside the local PACS or RIS. Enables cross-system study reconciliation and interoperability.

The facsimile number associated with the ordering provider, referring facility, or imaging center linked to a diagnostic study. Used to route radiology reports, imaging results, and prior authorization confirmations to the appropriate clinical or administrative destination.

The charge amount assessed for performing a diagnostic imaging examination, recorded at the study level for billing and revenue cycle processing. Used in claims generation, patient cost estimation, and financial reconciliation between imaging departments and payers.
