How does MRI generate images of the brain?

Using a strong magnetic field and radio waves
Through a series of intensive X-rays
By measuring electrical activity on the brain's surface
Through the use of ultrasound technology

The correct answer is: Using a strong magnetic field and radio waves

MRI, or magnetic resonance imaging, uses a strong magnetic field and radio waves to generate images of the brain. This works by detecting the different responses of different tissues to the magnetic field, allowing for detailed and high-resolution images to be produced. Option B, intensive X-rays, is incorrect because X-rays use ionizing radiation which can be harmful to the body and are not typically used in MRI. Option C, measuring electrical activity on the brain's surface, is incorrect because this is typically done through methods such as EEG, not MRI. Option D, ultrasound technology, is incorrect because ultrasound uses sound waves, not a magnetic field, to create images and is commonly used for imaging soft tissues, not the brain.
