CDUS is an acronym that stands for "Color Doppler Ultrasonography". This is a diagnostic imaging technique that uses sound waves to produce images of blood flow in the body. Synonyms for CDUS include "Doppler ultrasound", "color ultrasound", or simply, "ultrasound". Other related terms might include "vascular ultrasound", which refers to the use of ultrasound to examine blood vessels specifically, and "duplex ultrasound", which combines the use of standard ultrasound with Doppler ultrasound to produce a more detailed image. Regardless of the term used, CDUS is a versatile and non-invasive imaging technique that can provide valuable information about a wide range of medical conditions.
