Molecular Imaging of Inflammation in a Mouse Model of Atherosclerosis Using a Zirconium-89-Labeled Probe.

However, the TBRs (aorta-to-blood) from biodistribution data showed an increasing trend over time, with a peak at the 48 h, supporting imaging with radioisotopes with longer half-life when imaging atherosclerotic plaques to optimize the image contrast. 89 Zr has a lower e + energy than, for example, 68 Ga, and is comparable with 18 F or 64 Cu in this sense, which makes the radiotracer attractive for imaging applications of smaller structures.
