Triage Brain-CT Stroke Detector with Calibrated Uncertainty

FreeVerified credential3 weeksExpert

Overview

What this challenge is about.

You receive a curated public head-CT dataset (about 2,800 scans, slice-level labels for hemorrhagic stroke) and a held-out 600-scan hospital cohort. Train a 3D CNN or 2.5D slice-aggregating CNN for binary stroke detection. Add Monte-Carlo dropout for an uncertainty estimate. Evaluate AUROC, sensitivity at 95% specificity, and calibration (ECE + reliability diagrams) on the held-out cohort. Show how an 'uncertainty-aware' triage ordering compares with risk-only ordering on time-to-radiologist-read for the highest-priority 20% of cases. Deliver a 4-page memo.

The Brief

What you'll do, and what you'll demonstrate.

Train a stroke-detection model with calibrated uncertainty and show how an uncertainty-aware triage order changes time-to-read for top-priority cases.

Earning criteria — what you'll demonstrate

  • Apply a 3D / 2.5D CNN to a real medical-imaging classification task
  • Estimate model uncertainty via Monte-Carlo dropout
  • Calibrate model probabilities and report ECE on held-out hospital data
  • Translate uncertainty into operational triage-ordering claims
