Isotopes are important for medical imaging and treatments. However, there are some big challenges we face with them:

• Safety concerns: Isotopes give off radiation, which can be dangerous.
• Cost: Making isotopes can be very expensive.
• Availability: Many isotopes break down quickly, making them hard to get when needed.

Here are some possible solutions:

• Create safer isotopes.
• Find better ways to make isotopes that cost less.
• Work on better storage and transport options to keep isotopes available longer.
