Scatterplot demonstrating a strong correlation between 18F-fluciclovine SUV and percent tumor volume reduction on pathology in 24 patients with breast cancer following neoadjuvant therapy. Note that a 100% reduction in SUV on PET correlated with a 90-100% reduction in tumor reduction. Thus, while the correlation was strong, a 100% reduction in 18F-fluciclovine SUV could not distinguish a pathologic complete response from a pathologic non-complete response. ρ = Spearman’s rho.
