Fig. 5From: Aptamer-modified Magnetic Nanosensitizer for in vivo MR imaging of HER2-expressing CancerIn vivo MR images of HER2+ tumor mouse model using WMNCs (n = 3) or AptHER2-MNS (n = 3). a T2- and T2*-weighted MR images at the pre- or post-injection of WMNCs. b Relative signal intensity graph measured from a. c T2- and T2*-weighted MR images at the pre- or post-injection of AptHER2-MNS. d Relative signal intensity graph and e the intensity histogram of tumor region measured from c. f Histological analysis data obtained after MR imaging. Error bars were represented by positive y-axis only. Relative signal intensities of b, d, and e were measured from the red solid-lined ROI of a, c, and Additional file 1: Figure S4Back to article page
