Which area of study would typically use ultrasound as the primary imaging modality?

Ultrasound is primarily used in the field of obstetrics and gynecology due to its effectiveness in imaging soft tissues and developing structures. In obstetrics, ultrasound is essential for monitoring fetal development, assessing gestational age, and identifying any potential complications during pregnancy. It allows for real-time imaging, making it invaluable for observing fetal movement and heart activity.

In the realm of gynecology, ultrasound assists in evaluating the reproductive organs, diagnosing conditions such as ovarian cysts, fibroids, and ectopic pregnancies, and guiding certain minimally invasive procedures. The non-invasive nature of ultrasound, along with its safety for both the mother and fetus, solidifies its role as the primary imaging modality in this specialty.

In contrast, while ultrasound does have applications in oncology, emergency medicine, and orthopedics, its use is not as central as in obstetrics and gynecology. Other imaging modalities such as CT scans, MRIs, or X-rays may be preferred in those areas for various types of injuries or conditions.
