Flash sequence-based MRI imaging for morphologic evaluation of plagues. (A) 3D reconstructed images of the carotid artery at different time points before and after probe injection, along with corresponding 2D cross-sectional MRI images. The second column displays local magnifications of the first column; the third and fourth columns depict 2D cross-sectional MRI images corresponding to stenotic and normal proximal vessel ends, respectively. (Note: the red dotted line indicates lesion sites; the white dotted line indicates the normal lumen of the vessel proximal to the heart); (B) H&E staining of tissues at the lesion site and normal lumen of carotid tissues extracted from mice, accompanied by a schematic representation of the lesion site and normal lumen of carotid tissues. (Scale bar: 100 μm).
