Obese (BMI >30 kg/m2) patients receiving conventional CT scans are exposed to greater radiation than patients with BMI30 and they had both a conventional and low dose (LD) CT within 3 months of each other. LD was defined as dose-length product (DLP) 5 mm. Median difference in stone size between conventional and LD CT was 0.2 mm (p=0.1). The sensitivity for clinically significant stones (>2 mm) was 100%. None of the false negatives or the false positive on LD CT would have altered management. CONCLUSIONS: In our study, low dose CT in patients with BMI >30 kg/m2 accurately identified clinically significant stones while reducing risks associated with radiation exposure. These data suggest that LD CT scan can be considered in non-infected patients with obesity and BMI <40 kg/m2.
