Optimizing imaging protocols for overweight and obese patients: a lutetium orthosilicate PET/CT study.

Abstract

Lesion detectability and reader concordance peaked for 5 min/bed position scans, with no further diagnostic gain achieved by lengthening the duration of PET emission scanning. Thus, 5 min/bed position scans are sufficient for optimal lesion detection with LSO PET/CT in obese patients.
