Artificial Intelligence may diagnose dementia in a day 人工智能或能在一日內(nèi)診斷出失智癥
科學(xué)家正在測試一種人工智能系統(tǒng)，據(jù)信，僅需進(jìn)行一次腦部掃描，即可診斷出失智癥。該系統(tǒng)還有可能可以預(yù)測患者病情是會(huì)持續(xù)多年保持穩(wěn)定、緩慢惡化，還是需要立即接受治療。
Currently, it can take several scans and numerous tests over months or even years to diagnose dementia, but this new artificial-intelligence system might be able to identify dementia after just one brain scan.
目前，人們需要在數(shù)月甚至數(shù)年間進(jìn)行多次掃描和大量測試才能診斷出失智癥，但這種新的人工智能系統(tǒng)可能只需一次腦部掃描就能識(shí)別這一疾病。
It compares the scans of those who are concerned they might have dementia with those of thousands of patients who are confirmed to have the condition and their relevant medical records. An algorithm then identifies patterns in the scans that even expert neurologists can’t see.
該系統(tǒng)將那些擔(dān)心自己可能患病的人的掃描結(jié)果，與數(shù)千名失智癥患者的掃描結(jié)果以及相關(guān)病歷進(jìn)行比較。然后，一種算法會(huì)在掃描結(jié)果中識(shí)別出連神經(jīng)科專家都無法看出的固定模式。
In preclinical tests, it’s been able to diagnose dementia years before symptoms develop, even when there’s no obvious signs of damage on the brain scan. It’s now being tested at Addenbrooke’s Hospital in Cambridge to see if it works as well in a clinical setting as it has in the lab.
在臨床前測試中，即使腦部掃描沒有明顯損傷的跡象，該系統(tǒng)也能在癥狀出現(xiàn)的數(shù)年前診斷出失智癥?，F(xiàn)在，這種技術(shù)正在劍橋阿登布魯克醫(yī)院進(jìn)行測試，以觀察它在臨床環(huán)境中是否像在實(shí)驗(yàn)室中一樣有效。

答案
1. True or false? Currently, it can take years to diagnose dementia.
True. It can take several scans and numerous tests over months or even years to diagnose dementia.
2. What might the new artificial-intelligence system be able to do?
It might be able to identify dementia after just one brain scan.
3. What have preclinical tests of the system shown?
It’s shown to be able to diagnose dementia years before symptoms develop, even when there are no obvious signs of damage on the brain scan.
4. What is the system being tested for?
It’s being tested to see if it works as well in a clinical setting as it has in the lab.
