Measurement of Eosinophil Kinetics In Vivo

Methods Mol Biol. 2021:2241:183-191. doi: 10.1007/978-1-0716-1095-4_15.


Radiolabeled leukocyte scans are used in nuclear medicine to detect sites of infection and inflammation. We have previously demonstrated the use of clinical grade immunomagnetic beads to isolate autologous eosinophils and image their distribution in healthy volunteers. Here we describe the use of radiolabeled eosinophils coupled to single-photon emission computed tomography (SPECT) to quantify eosinophil uptake in the lungs of healthy volunteers, patients with asthma, and patients with focal eosinophilic inflammation.

Keywords: Cell trafficking; Eosinophils; Granulocytes; Imaging; Radiolabeling; SPECT.
