Contrast medial Liver neoplasms的用法和樣例：
例句
- Hypercalcaemia and hyperphosphataemia were absent, and there was no history of barium study or oral contrast ingestion.
患者無(wú)高鈣血癥和高磷血癥，也無(wú)鋇劑檢查或口服造影劑的歷史。 - After injection of contrast, small tumors are actually drowned by contrast material, so in this case CEUS is not helpful.
在注入造影劑后，小的腫瘤竟然被造影劑所掩蓋，因此對比增強超聲在這個(gè)病例中就顯得不是那么有用了。
