55-year-old woman (body mass index, 39.8) with treated liver metastasis from pancreatic endocrine tumor who underwent contrast-enhanced abdominal MDCT. Effective dose for low-dose series (filtered back projection [FBP] [top left], adaptive statistical iterative reconstruction [ASIR] [top right], and model-based iterative reconstruction (MBIR) [bottom left]) was 2.3 mSv, representing 88% reduction relative to standard-dose FBP series (bottom right). One reader detected only four low-attenuation liver lesions on low-dose ASIR images but identified at least seven focal liver lesions (per-organ maximum) on other images.
