Figure 1.

Columns A, B, and C correspond to the images before registration acquired at baseline before initiation of NAT (t₁), after one cycle of NAT (t₂), and at the conclusion of NAT (t₃). Columns D, E, and F correspond to the images after both intra- and interscanning session registrations. The rows correspond to the ADC, postcontrast DCE-MRI, THRIVE-MRI, CT, and the SUV of the FDG-PET, respectively. The contour of the THRIVE image at t₃ was copied to the other images in order to facilitate visual comparison of the registration results. The patient was a nonresponder (i.e., a non-pCR).
