Which patient group is described as the primary users of ultrasound as the imaging modality?

• A. Geriatric patients
• B. Pediatric patients
• C. Adult patients
• D. Neonatal patients

Answer: (B)

Ultrasound is favored because it uses no ionizing radiation, is portable, and provides real-time imaging that’s easy to perform at the bedside. These features are especially valuable in children, who are more sensitive to radiation and often require imaging multiple times. The ability to obtain dynamic, immediate results without sedation or exposure makes ultrasound a go-to tool in pediatric care for evaluating abdominal, genitourinary, musculoskeletal, and other issues. In newborns and infants, the open fontanelles also offer excellent acoustic windows for brain imaging and hip screening, highlighting its prominent role in this group. For these reasons, pediatric patients are described as the primary users of ultrasound as the imaging modality.
