Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

  • Generative models successfully detected anomalous attributes (needles, ascites) in unseen data.
  • Mean AUROC for failure detection was 0.86 (±0.13), and for data curation was 0.82 (±0.11).
  • Accurate localization of anomalies (81% ±13%) and differential performance of MSE/WD metrics observed.

Conclusions:

  • Generative models demonstrate promise for interpretable AI failure detection.
  • This approach facilitates unsupervised anomaly detection and aids large-scale medical data curation.
