T1-weighted FLASH images were obtained at 9.4 T to assess contrast of Lip-DTPA@AuNPs and Lip-DO3A@AuNPs (n = 3; two images are displayed; see Figure S7). Contrast-to-noise ratio (CNR) relative to muscle, computed from T1-weighted FLASH images, were overlaid on TurboRARE T2-weighted anatomical images at 9.4 T after administration of Lip-DTPA@AuNPs, Lip-DO3A@AuNPs, and no agents (control) following 24 h incubation. Upon administration of both Lip-Gd@AuNP constructs, significant contrast enhancement is observed in the region of the pancreas.
