派卓布魯加羅拉斯: 醫院為什麼有粒子加速器？

醫院為什麼有粒子加速器？

有沒有辦法在癌症和阿茲海默症太嚴重之前就先偵測出它們？醫生會將放射性藥物注射到身體循環當中，當作正子斷層掃瞄的偵測信號。這些診斷工具能比其他照影技術更早偵測出疾病的分佈。所以，這到底是怎麼做的？安全嗎？派卓布魯加羅拉斯帶大家來探究。

Hospitals use particle accelerators to create radioactive tracers that help detect diseases like cancer and Alzheimer's at their earliest stages. A single PET scan makes cancer cells light up like beacons, allowing doctors to spot tumors long before other imaging can. The process relies on rapidly produced isotopes, with half decaying in less than two hours, making timing crucial. Despite involving radiation, the exposure from a PET scan is about the same as spending two or three years around natural background sources.
