Impact of high densities induced by iodine-based contrast media on SA-PET/CT quantitative values: animal scans. Linear regression (a) and Bland-Altman analysis (b) of SA-PET/CT quantitative values in unenhanced PET/CT (UEPET/CT) as compared to contrast-enhanced PET/CT (CEPET/CT). Abdominal tumor-bearing nude mice and nude rats were sacrificed after the 18F-FDG uptake period, scanned without contrast media, and subsequently scanned after intraperitoneal injection of iohexol (3 mL, 100 mg I/mL).
