Clinical

The date of birth of the patient associated with a CT scan order or result record. Used to verify patient identity, calculate age-appropriate radiation dosing protocols, and support demographic matching in radiology information systems and clinical data warehouses.

The arterial blood pressure measurement recorded for a patient at the time of a CT scan procedure. Used to assess patient safety prior to contrast administration, monitor hemodynamic stability, and document pre-procedure vital signs in radiology and clinical workflow systems.

The date on which a scheduled CT scan was cancelled before completion. Used in radiology workflow management to track procedure abandonment, analyze scheduling efficiency, support rebooking workflows, and report cancellation trends across imaging departments and clinical systems.

The classification grouping assigned to a CT scan order or result, such as body region, clinical urgency, or scan type (e.g., contrast vs. non-contrast). Used in radiology information systems to organize imaging workflows, prioritize scheduling, and support utilization reporting.

The primary symptom or clinical reason documented by the ordering clinician that prompted the CT scan order. Used in radiology systems to guide scan protocol selection, support clinical decision-making, and ensure imaging appropriateness criteria are met during order entry.

An identifier or reference linking a CT scan record to a subordinate or dependent record within a hierarchical data structure, such as a series or image set under a parent study. Used in radiology information systems to manage parent-child study relationships and image organization.

The city associated with the facility, patient address, or referring location tied to a CT scan record. Used in radiology and clinical data systems to support geographic reporting, facility identification, and patient demographic documentation within imaging and health information systems.

The classification tier assigned to a CT scan, indicating scan type, service level, or clinical priority such as routine, urgent, or emergent. Used in radiology information systems to drive scheduling logic, resource allocation, and reporting stratification across imaging service lines.

The standardized procedural or billing code assigned to identify a specific CT scan type, such as a CPT or internal facility code. Used across radiology, claims, and clinical data systems to uniquely identify the imaging service for scheduling, billing, and outcomes tracking.

A free-text field capturing supplemental clinical notes, technologist observations, or workflow remarks associated with a CT scan record. Used in radiology information systems to document procedure-specific instructions, patient communication details, or follow-up actions not captured in structured fields.

The date on which a CT scan procedure was fully completed and marked as finished in the radiology information system. Used to measure procedure turnaround time, track imaging workflow efficiency, support result reporting timelines, and monitor departmental throughput metrics.

A flag indicating that a CT scan record or its associated clinical findings are designated as confidential, restricting access to authorized users only. Used in radiology and health information systems to enforce privacy controls for sensitive imaging studies such as psychiatric or substance-related evaluations.

The total number of CT scan procedures performed, ordered, or recorded within a defined scope such as a patient encounter, time period, or reporting cohort. Used in radiology analytics and clinical data warehouses to measure imaging utilization, monitor trends, and support population health reporting.

The country associated with the facility, patient address, or referring location linked to a CT scan record. Used in radiology and clinical data systems to support international patient identification, cross-border care coordination, and geographic demographic reporting within imaging information systems.

The system username or user identifier of the individual who created the CT scan record in the radiology or clinical information system. Used for audit trail documentation, workflow accountability, and data governance tracking to identify the source of record entry across imaging platforms.

The calendar date on which the CT scan record was first entered or generated in the radiology or clinical information system. Used to establish the audit timeline, track data entry workflows, and support record management and data quality monitoring within imaging and clinical data warehouses.

The timestamp indicating the exact time at which the CT scan record was first created in the radiology or clinical information system. Used alongside the created date to establish precise audit trail entries, support workflow timing analysis, and enable sequencing of radiology data events.

The serum creatinine lab value recorded for a patient prior to or in association with a CT scan procedure. Used in radiology workflows to assess renal function before administering iodinated contrast agents, helping to reduce the risk of contrast-induced nephropathy in at-risk patients.

The primary calendar date associated with a CT scan event, such as the date the scan was performed or scheduled. Used in radiology information systems and clinical data warehouses to anchor imaging records in time, support longitudinal tracking, and enable date-based reporting and analytics.

The combined date and time value representing a specific event in the CT scan workflow, such as procedure start, image acquisition, or result finalization. Used in radiology systems to enable precise temporal sequencing, turnaround time calculations, and timestamp-based audit and compliance reporting.
