What differentiates a diagnostic ultrasound from a screening ultrasound?

The key distinction between a diagnostic ultrasound and a screening ultrasound lies in their purposes and applications. A diagnostic ultrasound is performed to evaluate specific medical concerns, such as an abnormal finding detected during a screening mammogram or an area of interest identified by the patient, like a lump. This type of ultrasound aims to clarify a diagnosis and provide more detailed information about particular breast tissue areas.

In contrast, a screening ultrasound is typically conducted as a preventive measure to detect potential breast issues in asymptomatic women, particularly for those with dense breast tissue, where traditional mammography may not be as effective in rendering clear images. The goal here is to screen for abnormalities in a broader population rather than to address a specific concern.

Understanding these differences is crucial, as it impacts clinical decisions regarding the diagnosis and management of breast health.
