T1-weighted MR imaging of Gd-HPMA macrochelates at various concentrations. A: T1-weighted MR images of Gd-HPMA macrochelates with various CGd (0 ~ 200 μM) compared with the commercial Gadavist® and Magnevist® (200 μM) observed by a 3.0 T clinical MRI system. B: The black and white and corresponding pseudo-color images of T1-weighted MR images for Gd-HPMA macrochelates observed by a 7.0 T MRI scanner. C, D: ΔSNR of the MR images A, B for Gd-HPMA macrochelates with various CGd observed at 3.0 C or 7.0 T D
