What is the primary function of AI in the medical imaging industry?
|
To improve diagnostic accuracy and patient outcomes |
|
The primary function of AI in the medical imaging industry is to analyze medical images (e.g., X-rays, MRIs, CT scans) with high precision, helping clinicians detect abnormalities, diseases, or conditions more accurately and quickly. This leads to better patient outcomes, earlier interventions, and more personalized treatment plans. While AI can assist with administrative tasks or research, its main application in imaging is clinical decision support and diagnostic enhancement, not marketing or cost reduction. |
AI’s role in medical imaging demonstrates analytical, logical, and systemic thinking focused on enhancing patient care through improved diagnostics. |

Which of the following is a key benefit of AI in radiology noted in the article?
|
Acts as a second medical opinion |
|
A key benefit of AI in radiology is its ability to serve as a second opinion for clinicians, analyzing images to detect abnormalities that may be missed by human eyes. This enhances diagnostic accuracy, reduces human error, and supports radiologists in making more confident clinical decisions. Other options, like increasing the need for radiologists or reducing diagnosis speed, are incorrect, as AI is meant to assist, not replace, and to speed up rather than slow down diagnoses. |
Using AI as a second opinion demonstrates analytical, logical, and systemic thinking to enhance diagnostic reliability in radiology. |

According to the article, what is essential for increasing AI acceptability among medical professionals?
|
Designing human-centred AI systems |
|
The article emphasizes that AI acceptability increases when systems are human-centred, meaning they support healthcare professionals’ workflows, are intuitive, and complement rather than replace human decision-making.

What is the primary objective of using human embryonic stem cells in treating Parkinson’s disease?
|
To replace lost dopamine neurons. |
|
Parkinson’s disease is characterized by the loss of dopamine-producing neurons in the substantia nigra. Human embryonic stem cells (hESCs) are used to differentiate into dopamine neurons to replace the lost cells, restore dopamine levels, and improve motor function. Other options, like increasing brain size or general neurogenesis, are not the primary therapeutic goal. |
Supported by preclinical and clinical stem cell research showing functional recovery in animal models. |

Which animal was used to test the STEM-PD product for safety and efficacy?
|
Monkeys |
|
Monkeys were used to test the safety and efficacy of the STEM-PD product because non-human primates provide a closer model to human brain anatomy and physiology, especially for complex motor functions affected in Parkinson’s disease. Rodents are also used but primates are critical for translational studies before human trials. |

What role do growth factors like FGF8b and SHH play in the manufacturing process of STEM-PD?
|
They are used in cell patterning for specific neural fates. |
|
Growth factors like FGF8b and SHH direct pluripotent stem cells toward ventral midbrain dopaminergic neurons. They are critical for patterning cells to acquire the desired phenotype, not for general pluripotency maintenance or apoptosis. |
Widely documented in developmental neurobiology and stem cell protocols. |

What was a key outcome measured in the preclinical trials for efficacy in rats?
|
Recovery of motor function |
|
The primary preclinical efficacy outcome for Parkinson’s models is restoration of motor abilities, which directly reflects functional integration of transplanted dopamine neurons. Cognitive or lifespan changes are secondary or not assessed in this context. |
Behavioral assays in rats (rotarod, limb use) are standard measures for Parkinson’s therapies. |
