Objective:

To compare the enhancement features of splenic solid tumors on contrast-enhanced ultrasonography (CEUS) and contrast-enhanced CT (CECT).

Methods:

Twenty-one patients with focal splenic lesions were enrolled

including 5 cases of hemangioma

5 cases of lympho-hemangioma

4 cases of lymphoma and 7 cases of metastases. Their enhancement appearances were compared.

Results:

The vascular displaying rates of CEUS and CECT were both 100%. The two contrast methods were more sensitive than color Doppler ultrasound in displaying the perfusion of the splenic lesions (71.4%) (

P

0.05). Hemodynamic characteristics of the splenic lesions were accordant. The

detection rate of special performance of CEUS was 57.1% (12/21) in the enhancement process. Compared to that of CECT

the enhancement on CEUS was more diversified. The difference was statistically significant between CEUS and CECT images (

P

0.05).

Conclusion:

Both CEUS and CECT can demonstrate hemodynamic features of splenic tumors sensitively

which is helpful in differential diagnosis of splenic tumors.
