TABLE II.

Tumor-to-background contrast (dB) before and after TACE computed on power Doppler images with no filtering and with all possible combinations of IIR, SVD, CFPD, and adaptive demodulation (AD). GCNR values are indicated in parentheses. Change in contrast = C_before − C_after.

Method	Before TACE	After TACE	Change
No Filter	2.4 (0.19)	7.4 (0.64)	−5.0
IIR	2.2 (0.88)	−3.3 (0.91)	5.5
AD+IIR	1.8 (0.90)	−5.0 (1.00)	6.8
SVD	2.4 s(0.97)	−3.7 (1.00)	6.0
AD+SVD	2.3 (0.96)	−4.6 (1.00)	6.9
CFPD	0.1 (0.33)	2.2 (0.58)	−2.1
AD+CFPD	−0.7 (0.62)	0.1 (0.07)	−0.7
CFPD+SVD	0.4 (0.29)	3.7 (0.93)	−3.3
AD+CFPD+SVD	−0.4 (0.49)	2.6 (1.00)	−3.1
