Artificial intelligence predicts when heart will fail 人工智能程序可預測心臟衰竭

文字稿

科學傢們說，人工智能可以預測心臟疾病患者的死亡時間。這種軟件能夠通過分析驗血結果和心跳掃描看出心臟這一器官開始衰竭的征兆。英國醫學研究理事會（Medical Research Council）的研究小組稱，人們可以利用這項科技找出急需積極治療的患者，從而救助更多人的生命。請聽 James Gallagher 的報道。

An artificial intelligence can spot patterns that are beyond human perception. The software took MRI scans from hundreds of patients with pulmonary hypertension. The high pressure in the blood vessels and the lungs damages the structure of the heart. The AI used the scans to track the movements of 30,000 separate positions on a beating heart.

This information was combined with blood test data and eight years of medical records. As the computer programming learned what to look out for, it was able to predict when patients would die. It achieved 80% accuracy for the 12 months after the scan, which is more than doctors can manage.

One of the researchers, Dr Declan O’Regan, said that technology could help spot high-risk patients who needed to be treated more aggressively. Ultimately, the team want to use the technology in a wide range of heart disorders. The British Heart Foundation said the development was exciting, but the next step was to verify the findings before AI could be used routinely.

答案

1. What was the software able to do based on the knowledge of the patients’ condition?
Based on the knowledge of the patients’ condition, the computer programming was able to predict when they would die.

2. What information did the artificial intelligence analyse apart from the patients’ MRI scans?
Apart from the patients’ MRI scans, the artificial intelligence analysed blood test data and eight years of medical records.

3. True or false? The software predicted when patients would die with a higher accuracy than doctors.
True. The software achieved 80% accuracy for the 12 months after the scan, which is more than doctors can manage.

4. Which word in the text means ‘as a regular part of a procedure or process’?
Routinely.
