Breast imaging – Breast ultrasound – Ultrasound lexicon – Associated features – Vascularity
Vascularity in a mass or affected area of the breast can be detected by colour Doppler ultrasound. This complements the features of grey-scale B-mode ultrasound imaging. Colour Doppler ultrasound is used to determine internal vascularity, any vessels in the rim, and absent vascularity.
Internal vascularity describes the vessels seen within a mass lesion.
Vessels in rim
This term is used for vessels seen at the periphery of the mass lesion.
When no appreciable colour flow is seen in the region of the abnormality it is termed absent vascularity.
Vascularity in a lesion seen on Doppler ultrasound is caused by neoangiogenesis. It is not a specific feature that can be used to differentiate benign and malignant mass. Some features of colour Doppler ultrasound are useful for diagnosis.
