The 99mTc-3PRGD2 targeted SPECT/CT scanning was of significance in detecting differentiated glioma. In this work, the diagnostic value of 99mTc-3PRGD2 scintigraphy in brain glioma was evaluated by the ten clinically verified brain glioma patients after obtaining informed consent. The patients first accepted X-ray imaging to localize the detecting regions before administrating with 99mTc-3PRGD2 at a mean radioactivity of 849±115 MBq via single intravenous bolus injection 2 h prior to SPECT/CT imaging. Tumor samples for detecting αvβ3 were collected by surgical operations two weeks after the scintigraphy. The results of CT and SPECT scanning were merged and compared. The correlation between tumor occupation (T/N ratio) and αvβ3 expression level were analyzed. The T/N ratios in brain glioma were proportionally correlated to αvβ3 positive cell percentage (R2=0.9253, p<0.05). This study primarily evaluated the clinical application of 99mTc-3PRGD2 SPECT scintigraphy on brain glioma. The more pathological types and detecting strategies covering a large amount of samples would aid to clarify the potentials.
