What is the primary function of AI in the medical imaging industry?
|
To improve diagnostic accuracy and patient outcomes |
|
AI helps doctors by looking at medical images like X-rays, CT scans, or MRIs. Sometimes, small problems in these pictures are hard for people to see. AI can find those small problems faster and more correctly. This helps doctors know what is wrong with the patient and what treatment is best. That means patients can get better care and better results. |
The idea comes from computer science and health technology. AI systems learn from many images to know what diseases look like. This is called machine learning. When AI sees new images, it can compare and guess what it sees. Many research papers show that AI can help find diseases earlier and with better accuracy. So, using AI improves how well patients are diagnosed and treated. |

Which of the following is a key benefit of AI in radiology noted in the article?
|
Acts as a second medical opinion |
|
Because AI can support doctors by checking medical images and giving another idea about what it sees. This is like having a second person give their opinion. It helps make sure the doctor’s first diagnosis is correct or shows something the doctor might miss. So, AI works like a second opinion to help the doctor be more confident. |
This answer is based on the idea of decision support systems. In health care, AI is used to help, not to replace doctors. Research shows that when AI is used as a second opinion, it can help catch more problems and reduce mistakes. Machine learning helps AI learn from many examples, so it can give helpful advice when reading images. That makes diagnoses safer and more accurate. |

According to the article, what is essential for increasing AI acceptability among medical professionals?
|
Designing human-centred AI systems |
|
Doctors and healthcare workers are more likely to use AI if it is designed to help them in a simple and clear way. Human-centered AI means the system is easy to use, fits their needs, and supports their work, not just doing things automatically. This makes them feel more comfortable and in control. |
This idea is based on human centered design and the Technology Acceptance Model. These theories say that for people to accept a new tool like AI, it must be useful and easy to use. If AI is made with the user in mind ,like doctors and nurses , they will trust it more and want to use it in their work. |

What does the 'system usage' category of AI acceptability factors include according to the article?
|
Factors like value proposition and integration with workflows |
|
System usage is about how well the AI fits into the daily work of healthcare professionals. It includes things like whether AI brings good value and how easily it works with what doctors and nurses already do. If it fits smoothly into their routine, they’re more likely to use it. |
This comes from technology implementation theory and workflow integration models. These say that for a system like AI to be accepted, it must offer real benefits (value proposition) and be easy to add into current work systems. If AI feels like extra work or doesn’t match existing workflows, people will avoid using it. |

How does ethicality impact AI acceptability among healthcare professionals?
|
Affects views on AI based on compatibility with professional values |
|
Doctors and nurses want to use tools that match their values, like caring for patients, doing no harm, and keeping information private. If AI follows these values, they are more likely to accept and trust it. But if AI seems to go against these values, they may not want to use it. |
This is based on ethical decision ,making and value alignment theory. In healthcare, professionals make choices based on strong moral rules. If AI systems support these rules ,like fairness, patient safety, and privacy ,then people feel more comfortable using them. That’s why ethicality is very important for AI acceptability. |

What is the primary objective of using human embryonic stem cells in treating Parkinson’s disease?
|
To replace lost dopamine neurons. |
|
Parkinson’s disease happens when certain brain cells called dopamine neurons die. These cells help control movement. Human embryonic stem cells can be turned into new dopamine neurons. The goal is to put them into the brain to replace the ones that are gone, so the brain can work better again. |
This answer is based on regenerative medicine and stem cell therapy. Scientists use embryonic stem cells because they can become any type of cell in the body. In Parkinson’s, they focus on making dopamine neurons to restore lost brain function. This is one of the main goals in stem cell research for this disease. |
