Abstract
A modular radiation detector system has been developed by Lucerno Dynamics, LLC. Today’s version of the device collects data during the entire uptake portion of a molecular imaging study and then the data can be visualized and assessed for signs of infiltration. The objective of this study is testing the feasibility of this device for real-time assessment of the injected dose rather than the current mechanism that allows retrospective analysis of the acquired data. Real-time counts were collected manually from the device on twenty patients having a clinical PET scan. Time-activity curves were created from the manual real-time data and compared to the time-activity curve given from the device. The R2 value calculated for the averages across the two curves was 0.93 (93%) meaning the two curves did match. An external detector device may be used to ascertain that an injection is sufficient within only a 60-second acquisition.
