Investigation of Newly Prepared Biodegradable <sup>32</sup>P-chromic Phosphate-polylactide-co-glycolide Seeds and Their Therapeutic Response Evaluation for Glioma Brachytherapy

<div>Representative micro-SPECT/CT or micro-SPECT images in the SG and CG. Micro-SPECT/CT images on day 1 and micro-SPECT images on days 4, 16, and 64 were obtained after intratumoural injection of colloidal <sup>32</sup>P-CP ((a) <sup>32</sup>P-CP colloids were in irregular shapes with leak from injection site and much notable abnormal distribution and liver appearance) and intratumour implantation of <sup>32</sup>P-CP-PLGA seeds ((b) <sup>32</sup>P-CP-PLGA seeds demonstrated the shape of a dot. No significant difference or appearance of other organs was observed until 64 days). The white arrows refer to tumors.</div>
