Table 2 Comparison between computed tomography and double contrast-enhanced ultrasound for neoadjuvant chemotherapy response assessment n (%)

	Sensitivity	Specificity	PPV	NPV	Accuracy	χ²	P value
CT	13 (48.1)	10 (62.5)	13 (66.7)	10 (41.7)	23 (53.5)	0.427	0.663
DCUS	17 (62.9)	9 (56.3)	17 (70.8)	9 (47.4)	26 (60.5)	0.427	0.663

Double contrast-enhanced ultrasound (DCUS) had an overall accuracy of 60.5%, with a positive predictive value (PPV) of 70.8%. NPV: Negative predictive value; CT: Computed tomography.
