Objective:

To analyze the characteristics of enhancement pattern and time-intensity curve of contrastenhanced ultrasound (CEUS) of intestinal malignant tumors

and to evaluate the diagnostic value of CEUS in intestinal malignant tumors.

Methods:

A total of 26 patients with intestinal malignant tumors undertook CEUS examination. The enhancement patterns were observed. The quantitative parameters of tumor tissues and peritumoral intestinal wall were acquired by timeintensity curve.

Results:

CEUS showed that all the patients had heterogeneous enhancement pattern

and 7 patients with empty contrast areas in the lesions.

The lesions mainly showed high enhancement pattern

23 patients (88.5%) with high enhancement and 17 patients (65.4%) with centripetal enhancement. The lesions also mainly showed fast washout

22 patients (84.6%) with high enhancement maintaining for a short period of time and washed out quite early. There were significant differences in the absolute enhancement intensity and arrival to peak time between tumor tissue and peritumoral intestinal wall (

P

0.05).

Conclusion:

The intestinal malignant tumors have characteristic appearance on CEUS. The blood flow can be dynamically shown on time-intensity curve. CEUS is of clinical application value in the diagnosis of intestinal malignant tumors.
