ABSTRACT
Objective To compare the enhancement characteristic of the gallbladder diseases and to evaluate the diagnostic efficacy in differential diagnosis of the gallbladder diseases between contrast-enhanced sonography (CEUS) and contrast-enhanced computed tomography (CECT).Methods Seventy-two patiens with gallbladder lesions were examined by CEUS and CECT before operation and all final diagnoses were confirmed by surgery and/or pathological diagnosis.Results 1)In early phase,84.6% (33/39) and 79.5% (31/39) of benign diseases showed hyper-enhancement on CEUS and CECT,and 97.0% (32/33) and 87.9% (29/33) of malignant diseases showed hyper-enhancement on CEUS and CECT respectively (P =0.250).In later phase,91.2% (31/34) and 88.2% (30/34) of benign diseases showing hypo-enhancement (P =1.000),and 100% of the malignant diseases showing hypo-enhancement on CEUS and CECT respectively.2)The time of enhancement from hyper-to hypo in CEUS for benign and malignant diseases were (39.9 ± 15.7)s and (29.9 ± 5.6)s respectively (t =3.61,P =1.000).3)The inhomogeneous enhancement on CEUS and CECT were 41.0% (16/39) and 53.8% (21/39) in the benign diseases respectively (P =0.063),84.8 % (28/33) and 97.0 % (32/33) in the malignant diseases respectively(P =0.125).4)The destruction of the gallbladder wall on CEUS and CECT are 87.9% (29/33) and 90.9% (30/33) respectively(P =1.000).5)The accuracy,diagnostic sensitivity,specificity of CEUS and CECT were 91.7%(66/72) and 87.5%(63/72),97.0%(32/33) and 93.9%(31/33),87.2%(34/39) and 82.15% (32/39) respectively (P =0.250,1.000,0.500).Conclusions The enhancement pattern of the gallbladder diseases on CEUS and CECT were much similar.CEUS has equal diagnostic efficacy in comparison with CECT,but CEUS can supply more diagnostic information than CECT.
