Urgent findings surfaced hours sooner
AI-assisted prioritization and abnormality flagging cutting radiology turnaround by 18 hours.
A critical finding buried behind routine scans costs hours no patient can afford.
The Challenge
A 700-bed academic medical center processed 500+ daily imaging studies across chest X-rays, CT, and MRI. Average turnaround was 36 hours, with urgent findings sometimes buried in queue. Treatment delays caused measurable harm—delayed pneumothorax drainage, missed early-stage nodules, and patient dissatisfaction scores that lagged peer institutions. Radiologist recruitment could not keep pace with volume growth.
The Innovoco Solution
We implemented an AI-assisted radiology platform for chest X-rays and CT scans. AI models flag abnormalities for radiologist review, reprioritize the worklist by clinical urgency, and provide structured pre-reads that reduce per-study interpretation time.
Phase 1 — Validation on institutional data
Retrospectively validated models against 18 months of finalized radiology reports. Established sensitivity and specificity thresholds by finding class (pneumothorax, nodule, consolidation, effusion) with radiology leadership sign-off before any clinical integration.
Phase 2 — Worklist integration and monitoring
Integrated AI triage scores into PACS worklist ordering. Radiologists see flagged studies first with annotated pre-reads. A monitoring dashboard tracks concordance between AI flags and final reads; discordant cases feed quarterly model review.
Phase 3 — Expanded modalities
Extended coverage to CT pulmonary angiography and abdominal CT with institution-specific fine-tuning, maintaining the same validation and monitoring rigor.
Key implementations
Urgency-based worklist reordering
AI confidence scores reprioritize the PACS reading queue so critical findings surface within minutes of acquisition, not hours.
Annotated pre-reads
Structured overlays highlight regions of interest with finding-class labels, reducing per-study cognitive load without replacing radiologist judgment.
Concordance monitoring
Automated comparison of AI flags versus final radiology reports tracks sensitivity drift and generates alerts when performance degrades.
HIPAA-compliant architecture
All inference runs within the institution's HIPAA boundary; no PHI leaves the secure enclave. BAAs executed with all infrastructure providers.
Technical Innovation
AI models run directly within the hospital's imaging network—no data leaves the secure environment, no new interfaces for radiologists. Studies are scored and annotated within the same system radiologists already use.
Impact
- 90%+ diagnostic sensitivity across primary finding classes after institutional validation.
- 18-hour reduction in average turnaround for flagged urgent studies.
- 40% fewer diagnostic errors on studies where AI pre-read was available.
- Radiologist throughput increased without additional FTEs, absorbing 12% annual volume growth.
Radiologists still make every diagnosis—but they see the most urgent studies first, with structured pre-reads that make each minute of reading time more effective.
