About this Radiology Turnaround Time Calculator

Radiology turnaround time can be measured from order, exam start, exam complete, preliminary report, or final report. This calculator exposes the common intervals.

Who this calculator is for

  • Radiology operations leaders.
  • Imaging informatics teams.
  • PACS/RIS analysts tracking TAT.

When to use it

  • Calculate exam-to-final report time.
  • Separate acquisition delay from reporting delay.
  • Compare preliminary and final report intervals.

How to use this calculator

  1. Enter timestamps for order, exam start, exam complete, preliminary, and final report.
  2. Review operational intervals.
  3. Use consistent start and stop definitions in reports.

Key assumptions

  • Times are entered on the same date unless crossing midnight is handled by the browser date-time values.
  • This is an operational calculator, not a clinical triage tool.
  • No timestamps are stored.

How this calculator works

Intervals are calculated as elapsed minutes between entered timestamps. Negative or missing sequences return invalid interval values.
Each output is the elapsed minutes between two entered workflow times on the same operational day.

Inputs explained

Exam complete time

Often used as the start point for radiologist reporting turnaround.

Preliminary report time

Optional intermediate reporting milestone.

Final report time

Final signed report timestamp.

Understanding your results

Use the interval that matches your KPI definition. Emergency, inpatient, outpatient, and screening workflows may use different rules.

Example scenarios

Report TAT

Exam completed at 10:00 and final report at 11:45 gives 105 minutes exam-to-final TAT.

Key Features

  • Instant Calculation
  • Private & Secure
  • Mobile Optimized

Tips & Best Practices

  • Define TAT consistently before comparing teams.
  • Separate acquisition, queue, interpretation, and signing delays.
  • Use medians and percentiles for reporting, not only averages.

Frequently Asked Questions

Which turnaround interval should I use?
Use the interval your department defines, often exam complete to final report for reporting TAT.
Does this adjust for priority or modality?
No. Run separate scenarios or reports for priority/modality segments.
Are timestamps stored?
No. The calculation runs locally.
