Ultrasmall NaGdF₄ Nanodots for Efficient MR Angiography and Atherosclerotic Plaque Imaging

Herein, ultrasmall NaGdF4 nanodots (~2 nm) with DTPA conjugation have been synthesized for efficient MR angiography. Impressively, the r1 value in MRI reaches up to 8.93 mM−1·s−1. The ultrasmall vessel lumen of a rabbit is lighted up remarkably. After 3 h, atherosclerotic plaques could be discriminated clearly. This is beneficial for the accurate early diagnosis of vascular pathema. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
