What is the primary function of AI in the medical imaging industry?
|
To improve diagnostic accuracy and patient outcomes |
|
AI is used to analyze previous old data and predict future data by new inputs. |
AI can perform quantitative analysis and have a higher diagnostic accuracy than humans. Thus, improve patient outcomes. It can also manage and organize the hospitals resources for a faster system. AI can help with prioritization and triage, enhance monitoring of medical symptoms, and improve diagnostic medicine. |

Which of the following is a key benefit of AI in radiology noted in the article?
|
Acts as a second medical opinion |
|
AI can help schedule and makes improvement on workflow. It increases the speed of diagnosing. AI cant provide second medical opinion like humans |
Radiologists have to do many ques of imaging studies and this can cause there to be less accuracy. AI algorithms helps in triage and provide automated measurements and quantifications. |

What is the primary objective of using human embryonic stem cells in treating Parkinson’s disease?
|
To replace lost dopamine neurons. |
|
Embryonic stem cells are used in cell therapy to grow dopamine neurons. |
Loss of dopamine neurons results in Parkinson disease. The use of stem cells to grow dopamine cells can cure Parkinson or reduce its effects. |
