Evaluation of contrast-enhanced ultrasonography in diagnosis of focal splenic solid lesions / 中华超声影像学杂志

ABSTRACT

Objective To investigate the value of contrast-enhanced ultrasonography(CEUS) for differential diagnosis of focal splenic solid lesions.Methods Thirty-two patients with 32 focal splenic lesions were examined with CEUS.The enhancement phases and perfusion were observed.Each group has 16 patients.Results The contrast media extincted more quickly in malignant lesions than in benign ones.The peak time and initial decreasing time of the malignant lesions were (19.7±4.5)s and (29.7±10.9)s.The opposite time of the benign lesions were (24.2±4.4)s and (50.9±22.8)s.The initial decreasing time of the malignant lesions was earlier than that of the benign ones.The enhancement pattern was similar between the two groups.More lesions can be detected after CEUS.The number of the lesions was 111 before CEUS and 142 after CEUS.Conclusions CEUS is useful in the differential diagnosis of splenic lesions.
