Total-body PET/CT scanner yields diagnostic-quality images in one minute

A long-axial field-of-view PET/CT system produced whole-body images in 1 minute that readers rated higher than standard-of-care scans (mean diagnostic quality score 4.5 vs 3.9 on a 5-point scale), according to data presented at EANM'26.

• The 128-cm Omni system (GE HealthCare) scored 5.0, 4.9, and 4.5 for 10/5-minute, 3/2-minute, and 1-minute acquisitions, respectively, across five radiotracers including FDG, PSMA, and DOTATATE.
• One-minute images retained diagnostic quality (≥3/5 in all categories) but showed increased noise compared to longer scans.
• Researchers caution that the study assessed image quality, not diagnostic accuracy for small or low-contrast lesions, and larger clinical validation is needed.
