A US and CEUS of a 67-year-old woman with a 3.0 cm hypoechoic solid lesion in the head of the pancreas. a The lesion was not in a taller-than-wide shape in the longitudinal plane. b The TTP was 24 s and the Peaktumor/Peaknormal was 0.772 (in the transverse plane). c The lesion in the venous phase (in the transverse plane). d A total of 170 points were assigned to the lesion according to the nomogram, corresponding to an about 90% probability of “responders”. After 4 cycles of NAC, a radiographic response of SD was achieved. B The pre-treatment (a, b) and post-treatment (c, d) CT images of the case. CA 19–9 decreased from 50.8 to 20.3 U/mL
