Is ultrasound good or bad?

Ultrasound is generally considered a good and valuable medical tool. It uses high-frequency sound waves to create images of the inside of the body, which can help diagnose and monitor various conditions. Here are some of the key benefits:

1. Non-invasive: Ultrasound doesn't require any incisions or injections, making it a relatively simple and safe procedure.
2. No radiation: Unlike X-rays or CT scans, ultrasound doesn’t use ionizing radiation, so it’s considered safer, especially for pregnant women and developing fetuses.
3. Real-time imaging: It provides real-time images, which can be useful for guiding certain procedures and monitoring dynamic processes like blood flow.
4. Versatility: It can be used to examine many different parts of the body, including organs, tissues, and blood vessels.
