Abstract
We evaluated a compact and cost-effective radio thin-layer chromatography (radio-TLC) scanner for the quality control (QC) of radiopharmaceuticals. We adapted a scintillation detector, which is a Gd3Al2Ga3O12 (GAGG:Ce) scintillation crystal array coupled with a photodiode array. The performance of the scintillator array-based radio-TLC was compared with that of a commercial device. We scanned 1 μCi/μL of Tc-99m and F-18 with each device. The difference between the ROI count ratios of the developed and commercial scanners was less than 1.2%. Our scanner is sensitive enough to take measurements for a radiochemical purity test.
