FIGURE 3. Limits of agreement for normalized segmental 18F-FDG uptake in FBP-Pre and FBP-Post (A), FBP-PostTIS (B), FBP-PostDP (C), and OSEM-Pre (D). Horizontal lines represent the mean difference and mean ± 2 SD. (A) Mean = -1%; 2 SD = 10%. (B) Mean = -1%; 2 SD = 11%. (C) Mean = 0%; 2 SD = 8%. (D) Mean = 1%; 2 SD = 4%.
