Résumé
The whole-body absolute quantification of Lu-DOTATATE therapy was achieved using a high-speed 360° CZT SPECT/CT system. Twelve high-resolution swelling detectors may be positioned close to patients, providing a high-count sensitivity that is particularly advantageous for the low-count rate conditions of Lu imaging. After initially validating Lu quantification on phantom, serial whole-body SPECT/CT acquisitions of only 20 minutes were obtained for a 70-year-old woman treated by Lu-DOTATATE injections for a metastatic recurrence of a pancreatic neuroendocrine tumor. The progressive decrease in tumor uptake between the consecutive Lu-DOTATATE injections could be quantified, and thereby the corresponding dosimetry changes could be estimated.
