Figure 3. Representative ultrasonography (US) images (A), contrast-enhanced US (CEUS) images (B), and time–intensity curve (C) for a case of non-lymphocyte-predominant breast cancer (LPBC). US tissue characterisation showed an irregular shape, extremely low internal echo level, and accentuated posterior echoes. The ascending slope value calculated from time–intensity curves using CEUS was 8.64. The tumour-infiltrating lymphocyte (TIL)-US and TIL-CEUS scores for this case were 4 points for both; LPBC was predicted from the TIL-US score and non-LPBC from the TIL-CEUS score.
