Teleradiology Turnaround Time: What Imaging Centers Should Expect in 2025
Reviewed by board-certified radiologists
Turnaround time (TAT) is one of the most important metrics in teleradiology — yet it's also one of the most inconsistently defined. Before you can benchmark your current provider or evaluate a new one, you need to understand what TAT actually means, what drives it, and what realistic expectations look like for different study types.
How Is Teleradiology Turnaround Time Defined?
TAT is typically measured from the time a study becomes "available to read" in the teleradiology platform to the time a signed report is returned. This sounds simple, but different providers measure it differently. Some measure from when the DICOM transfer begins. Others measure from when the last image arrives. A few measure from when the radiologist actually starts reading. Always clarify exactly how your provider measures TAT before signing a contract.
Industry Benchmark TAT by Modality
| Study Type | Standard TAT | STAT TAT |
|---|---|---|
| Chest X-Ray | 15–30 minutes | 10–15 minutes |
| Extremity X-Ray | 20–30 minutes | 10–15 minutes |
| CT Head | 30–60 minutes | 15–30 minutes |
| CT Abdomen/Pelvis | 45–90 minutes | 20–30 minutes |
| MRI Brain | 60–90 minutes | 30–45 minutes |
| MRI Spine | 60–90 minutes | 30–45 minutes |
| Mammography (Screening) | 24–48 hours | N/A |
| Mammography (Diagnostic) | 2–4 hours | 1–2 hours |
What Causes Slow Turnaround Time?
- Radiologist queue depth: If your provider's reading pool is understaffed during overnight or weekend hours, studies pile up in queue. Ask your provider how many radiologists are actively reading during off-hours.
- DICOM transfer speed: Slow PACS-to-reading-platform transfer is a common culprit, especially for high-slice CT studies or large MRI sequences. Proper HL7/DICOM configuration and bandwidth optimization can cut transfer time significantly.
- Routing and prioritization logic: Without smart routing, STAT studies can get buried behind routine reads. Good teleradiology platforms automatically route STAT studies to the front of the queue.
- Report generation bottlenecks: If radiologists are dictating into a separate system rather than using structured report templates, final report delivery adds minutes to every study. AI-generated report templates eliminate this delay.
How AI Reduces Teleradiology Turnaround Time
AI-enhanced teleradiology platforms like Natoe AI reduce TAT in two concrete ways. First, AI pre-screens studies for critical findings — flagging pneumothorax, intracranial hemorrhage, or PE before the radiologist even opens the study. Second, AI auto-populates structured report templates based on AI analysis, so the radiologist spends time interpreting rather than transcribing. The result is a 30–50% reduction in effective reading time for routine studies.
What to Put in Your SLA
When negotiating a teleradiology SLA, be specific. Define TAT separately for: routine reads by modality, STAT reads, and critical findings. Specify the clock start and stop points. Include escalation procedures for missed TAT commitments, and require monthly TAT reporting so you can hold your provider accountable. A provider that won't put TAT commitments in writing is a provider to avoid.
Natoe AI provides contractual TAT SLAs for all study types, with real-time dashboards so imaging center administrators can track TAT performance continuously — not just in monthly reports.
