癌症導因斷層掃瞄？ 專家呼籲少用
台灣醒報/ 2012/06/18

電腦斷層掃瞄即慣稱的C.T. Scan，是目前肺癌最先進、最普遍的篩檢法，但最新一期的「美國醫藥協會期刊」卻警告，直線上升的掃瞄使用率，將使病患過度暴露於輻射之中，如果美國C.T. Scan的使用以目前的速率增加下去，未來將有兩成癌症會導因於此。

肺癌的致死率高，主要是早期肺癌無症狀，不易察覺，一旦發現可能又為時已晚。C.T. Scan是利用電腦所拍攝的人體Ｘ光顯影技術，來偵測早期的癌症。隨著醫療科技的發達，越來越多的醫生和病人都指定以低劑量輻射的電腦斷層掃瞄，來做癌症篩檢，特別是肺癌。

據本月出刊最新一期的「美國醫藥協會期刊」（Journal of the American Medical Association）指出，美國1996年的C.T. Scan使用率，每一千人中有52人；2010年飆升到了每千人就有149人使用。從1996年到2010年，電腦斷層掃瞄的使用增加了三倍，而在這長達15年的研究期間，接受高劑量到極高劑量掃瞄的病患人數也增加了兩倍。

不過，關於C.T. Scan輻射的副作用，已經不是新話題，早在2009年，國家癌症研究所（National Cancer Institute）所提的研究報告，就已提出相同的警告，即病患透過這項高科技的電腦掃瞄，將使自己過度暴露於輻射之下，美國會因此增加成千上萬的癌症病人，因而呼籲醫界減少使用C.T. Scan，如果必須使用，也儘量減少輻射劑量。

去刑化之前
該用斷層掃瞄還是不要手軟
必要時還要stat

這絕對嚇不跑需索無度的刁民的啦 ! (樂奔)

到底是怎樣???

沒做電腦斷層---說你誤診

做了電腦斷層---說會致癌

鬼島真的名副其實------難怪4大科沒人要去了
