Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201470157-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>As shown by J. Shi, W. Bu, and co‐workers on page 3867, ultrasmall NaGdF₄ nanodots (ca. 2 nm) with diethylenetriaminepenta‐acetic acid (DTPA) conjugation are synthesized for efficient magnetic resonance (MR) angiography. Impressively, the <italic>r</italic>₁ value in magnetic resonance imaging (MRI) reaches up to 8.93 mM⁻¹ s⁻¹. The ultrasmall vessel lumen of a rabbit is lit up remarkably. After 3 h, atherosclerotic plaques can be discriminated clearly. This is quite favorable for the accurate early diagnosis of vascular pathema. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pghmfn3s7c" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
