Quiz · AI in Medical Diagnosis

Question 1What is the speaker's main point about artificial intelligence in medical diagnosis?

It has already replaced doctors in most modern hospitals around the world It supports specialists but cannot by itself guarantee better patient outcomes It should be abandoned because it misses more tumours than radiologists It performs consistently well across all types of scanning equipment

Question 2According to the lecture, what worried hospital managers most about the new software?

The high purchase price of the diagnostic software The risk of the software replacing junior radiologists The time and money required to train staff properly The postponement of the clinical trial until September

Question 3When was the trial finally held after its postponement?

September March June December

Question 4In which country was the recent study mentioned by the speaker carried out?

Denmark Sweden Finland Norway

Question 5What did the Danish study initially suggest about the diagnostic program?

It worked equally well with every kind of scanning machine It missed fewer tumours than junior radiologists did It performed far worse than any of the junior radiologists It required far more training than the hospital staff expected

Question 6What did further analysis of the study reveal about the software?

It replaced the need for a second reader in most hospitals It identified more tumours than senior specialists could It performed poorly with images from older scanning machines It reduced the cost of training hospital staff considerably

Question 7How did researchers react to the findings about older scanning machines?

They were relieved that the problem had been identified early They were angry that the hospitals had hidden the results They were confident the software would quickly be improved They were surprised because they had expected consistent performance

Question 8Which statement is closest in meaning to how hospitals actually use the software?

It takes over most routine work from medical specialists It checks diagnoses alongside specialists rather than replacing them It trains junior radiologists to recognise tumours more quickly It decides which patients should be seen by specialists first

Question 9What mistaken assumption do many people make about these AI systems?

They believe the systems are already replacing doctors They believe the systems are too expensive for hospitals They believe the systems require too much staff training They believe the systems only work in Danish hospitals

Question 10What will the speaker discuss in next week's lecture?

How older scanning machines can be replaced cheaply Why most hospitals refuse to adopt diagnostic software How the Danish study was designed and funded How doctors and algorithms can work together effectively
