FAQs
1. Is an ultrasound procedure painful or uncomfortable?
Generally, ultrasound procedures are not painful. You might feel some pressure as the sonographer moves the transducer, especially when imaging deeper organs, but a water-based gel is used to help the transducer glide smoothly.
2. Are there any side effects or risks associated with diagnostic ultrasound?
Diagnostic ultrasound is considered one of the safest medical imaging modalities available. It doesn’t use ionizing radiation, and the sound waves used are at very low power and do not cause any known harmful effects to the body, even for sensitive populations like pregnant women and children. The gel used is hypoallergenic, meaning it is designed to minimize the risk of allergic reaction.
3. What factors can affect the clarity or quality of an ultrasound image?
Several factors can influence the clarity of an ultrasound image, including the presence of excess body fat or significant muscle, and the presence of gas or air, such as in the bowel or lungs. Additionally, the skill and experience of the sonographer play a significant role.
