The correct answer emphasizes that ultrasound imaging carries minimal risks, particularly in the context of its widespread use and safety record. Ultrasound utilizes sound waves rather than ionizing radiation, which is why it is generally considered safe for both patients and practitioners.

Although unnecessary ultrasound exams should be avoided due to the potential stress they may cause to patients, this concern is primarily about optimizing patient care rather than a direct risk of the imaging technology itself. Routine and medically justified use of ultrasound has shown to have few adverse effects, particularly in comparison to other imaging modalities.

The other options highlight misconceptions or risks that are not typically associated with ultrasound. There is no significant risk of tissue damage from the procedure when it is performed correctly. Ultrasound does not involve any radiation exposure, which is a significant risk factor in other imaging techniques. Lastly, while gels used during ultrasound can, in rare cases, cause allergic reactions, this is not a common risk factor associated with the imaging process itself.
