NTUH's Wu Ming-shian says the fact that PET scans are expensive (NT $ 30-50,000 each) and that Taiwan and Japan are the only two nations in the world to use them as screening devices reflects the Taiwanese and Japanese public's willingness to spare no expense when it comes to cancer detection.
台大健康管理中心主任吳明賢表示，正子掃描價格高昂（每人每次約 3-5 萬台幣），而台灣與日本是當前世界上「唯二」以正子掃描作為健檢器材的國家，反映出部分台、日民眾「癌檢不惜代價」的心理。
