Biomedical Engineering and AI in Medicine

Researchers at Johns Hopkins University are developing AI technologies to improve heart and cancer patient care. They create digital twins of patients' hearts to predict cardiac risks and use AI to detect cancer through blood tests. Ethical considerations for AI in medicine are also discussed, emphasizing the need for rigorous standards and transparency.

What is the primary goal of creating a digital twin of a patient's heart?

• To improve the aesthetic appearance of medical imaging

• To predict the risk of sudden cardiac death

• To replace traditional heart surgeries

• To eliminate the need for defibrillators

How does Professor Tranova's research aim to improve heart disease predictions?

• By using segmented images of the heart

• By using only patient history

• By combining MRI with clinical data

• By focusing solely on genetic data

What is the main advantage of using whole images of the heart in predictions?

• They are easier to store

• They are cheaper to produce

• They require less processing power

• They provide more accurate predictions

What is the focus of Dr. Velculescu's research at Johns Hopkins?

• Developing new heart disease treatments

• Creating digital twins for cancer patients

• Detecting early-stage cancers

• Improving MRI technology

How does the team detect cancer using cell-free DNA?

• By using traditional blood tests

• By identifying chaotic patterns in DNA fragments

• By sequencing the entire genome

• By analyzing the uniformity of DNA fragments

What is a potential benefit of improved blood tests for cancer detection?

• They can replace all imaging techniques

• They can increase global cancer screening

• They can eliminate the need for biopsies

• They can cure cancer

What is a major concern regarding the use of AI in medicine?

• The complexity of AI algorithms

• The ethical implications of its deployment

• The lack of available data

• The high cost of AI technology

What does the WHO recommend for AI in healthcare?

• Complete automation of medical procedures

• Unrestricted use of AI tools

• Transparency and cybersecurity protections

• Elimination of human oversight

Why is rigorous evaluation of AI systems important?

• To reduce their complexity

• To ensure they are cost-effective

• To prevent them from amplifying biases or errors

• To make them faster

What should be considered when deploying AI tools in medicine?

• Their ability to work offline

• Their entertainment value

• Their safety and efficacy standards

• Their ability to replace doctors
