Results of comparison of fundamental versus combination of tissue harmonic imaging (THI), spatial compounding (SC) (cross beam: level low) and speckle reduction imaging (SRI) level 1

Criteria	−1	0	+1
Margin	1	11	12
Infiltration (existent in 19/24 malignant cases)	1	3	15
Echo pattern/tissue components	3	10	11
Calcifications	1	2	3
Posterior lesion boundary	1	7	16
Posterior acoustic features	9	9	6

Score : −1=fundamental superior, 0=no difference, +1=combination superior
