Ultrasound vascular imaging with subtraction in evaluation of lung tumor vascularity--a case report

Ultrasound vascular imaging with subtraction is considered as very useful method to evaluation vascularity of tumor and its relationships to great vessels. Lung tumor was evaluated with power color Doppler ultrasound with and without B-mode scanning. Power color Doppler imaging without B-mode scanning is better depicted tumor internal vascular architecture and its relationships to great vessels then with B-mode. This method makes differentiation of tumor character possibly and interventional procedures more safely.
