Small part sonography is a diagnostic imaging technique focused on examining superficial structures such as the thyroid gland, breast, scrotum, lymph nodes, and other small organs or tissues. Using ultrasound technology, small part sonography produces detailed real-time images, allowing clinicians to assess for abnormalities, masses, cysts, inflammation, and other conditions affecting these structures. This non-invasive procedure is commonly used in various medical specialties, including endocrinology, oncology, urology, and radiology, for diagnostic purposes, monitoring of known conditions, and guiding interventions such as biopsies or aspirations. Small part sonography offers advantages such as high resolution, lack of ionizing radiation, and the ability to perform dynamic assessments, making it a valuable tool in the evaluation and management of a wide range of medical conditions.
