What imaging technique is commonly used to assess internal structures?

The sonogram, known more commonly as ultrasound, is an excellent imaging technique used to assess internal structures, particularly soft tissues and fluid-filled cavities. This non-invasive method employs high-frequency sound waves to produce images of organs and other structures inside the body. It is particularly useful for examining the heart, blood vessels, kidneys, liver, and developing fetuses during pregnancy.

Ultrasound is preferred in numerous situations due to its safety profile, as it does not use ionizing radiation, making it suitable for a wide range of patients, including pregnant individuals. Additionally, sonograms can be performed in real-time, allowing providers to observe movement and blood flow, enhancing diagnostic capabilities.

While CT scans and MRI are also valuable imaging modalities used in various contexts for detailed views of the body's internal structures, they may not always be the first choice for certain types of assessments, especially when soft tissue evaluation is critical. X-rays are effective for evaluating bone structures and detecting fractures, but they have limitations when it comes to soft tissues compared to ultrasound.
