Ultrasound microbubbles in diagnosis of buccal carcinoma

To explore the enhancement effect of contrast media on primary cancer of cheek carcinoma by local injection. The carcinoma mice models were established, then self-made contrast media was administered into the primary cheek carcinoma, and harmonic mode imaging was performed to observe the enhancement of primary lesions. The echo intensity (EI) was compared, after contrast-enhanced ultrasound (CEUS) imaging, the EI of primary cancer was increased. After injection of self-made contrast media via the primary lesion, it can obviously enhance the effect of ultrasonography on cheek carcinoma.
