|Can contrast-enhanced ultrasonography (CEUS) distinguish benign from malignant soft-tissue masses? Prelimirary results|
All patients tollerated the sonographical examination well without side effects related to ultrasound contrast agent. Eighty-eight benign and 117 malignant lesions were diagnosed by histology. In all masses, seven different CEUS patterns and three different vascular timing were observed. 90% of the malignant lesions (105/117) show a rapid early time of vascularisation (arterial phase) and 60% (70/117) an inhomogenous enhancement pattern with avascular areas. Only 20% of benign lesions (11/88) show a pattern similar to malignant lesions and 50% (44/88) showed a rapid time vascularization: histologically, these last arterial pattern was characteristic of arterio-venous malformation and hemangioma (Fig. 4, 5, 6).
