ABSTRACT

Objective To compare the diagnostic value of Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) enhanced MRI and contrast-enhanced ultrasound (CEUS) in detection of small hepatocellular carcinoma (sHCC).Methods A total of 22 patients with 29 lesions who underwent Gd-EOB-DTPA enhanced MRI and CEUS scan,and confirmed as sHCCs by pathology were included in this study.Gd EOB DTPA enhanced MRI pattern for the conclusive diagnosis of sHCC were lesions showed iso or low signal on T1 WI,showed slightly high signal or high signal on T2 WI,showed high signal on DWI and obviously enhanced in the arterial phase and/or clearance in the hepatobiliary phase;CEUS pattern for the conclusive diagnosis of sHCC were rapidly increasing in the arterial phase and showing low echo in the delay phase.Results The diagnostic sensitivity of detecting sHCC by Gd EOB-DTPA enhanced MRI and CEUS were 82.76% and 65.52% respectively,and there was no statistical difference (x2 =2.248,P=0.134),the diagnosis specificity were both 100 %.Conclusion Both of the diagnostic sensitivity and specificity for detecting sHCC by Gd EOB DTPA enhanced MRI and CEUS showed no difference,the value of diagnostic sensitivity of the former is higher.
