View larger version (90K): [in a new window]   Figure 3. 56-year-old patient with lung cancer and metastases within the chest wall. (a) On power Doppler ultrasound a large vessel was seen in the tumour which infiltrates the chest wall. The tumour involvement is bordered by a pleural effusion. (b) A monophasic high impedant arterial flow pattern was seen suggesting an intercostal artery (ICA).

(a) On colour Doppler ultrasound a vessel was seen centrally in the tumour. (b) A monophasic high impedant arterial flow pattern was seen suggesting an intercostal artery (ICA). (c) In the periphery of the lesion a monophasic low impedant arterial flow pattern was seen suggesting a peripheral bronchial artery (BA) origin.

(a) On colour Doppler ultrasound mapping vessels were seen in the central region of the tumour. (b) A triphasic high impedant arterial flow pattern was seen suggesting a pulmonary artery (PA) origin. (c) Beneath the PA an additional flow signal (FS) characterized as a monophasic low impedant arterial flow pattern was seen suggesting a central bronchial artery (BA) origin.

(b) A monophasic nearby constant flow pattern that lacks systolic–diastolic variation was seen suggesting tumour neoangiogenesis (TN).

View larger version (93K): [in a new window]   Figure 7. (a) On colour Doppler ultrasound mapping small vessels originated in the chest wall were seen in the peripheral region of the tumour. (b) A monophasic high impedant arterial flow pattern was seen suggesting an intercostal artery (ICA) origin.
