Abstract:
Objective To evaluate contrast-enhanced ultrasonography (CEUS) in diagnosis of small hepatocellular carcinoma (SHCC) ( ≤ 2. 0 cm) with liver cirrhosis after contrast-enhanced CT (CECT) examination. Methods Forty five patients with liver cirrhosis received CECT and CEUS examinations before operation or needle biopsy and the diagnosis was confirmed by pathological examination.CEUS and CECT findings of 51 liver space-occupying lesions from 45 patients were retrospectively analyzed.Results Among all 51 lesions detected CEUS and CECT found 49 and 35, respectively. The typical characteristics of SHCC were "fast-in and fast-out" and "fast-in and slow-out". The sensitivity of CEUS and CECT in diagnosis of SHCC was 88. 9% (32/36) and 69. 4 % (25/36) respectively ( x2 = 3. 02, P =0. 08);the diagnostic accuracy was 84. 3 % (43/51 ) and 56. 9% (29/51 ) respectively ( x2 = 1.46, P =0. 22). Among 16 lesions missed by CECT, 12 were detected by CEUS. Conclusions CEUS and CECT show the similar diagnostic rate for typical SHCC ,however, CEUS is more sensitive for atypical lesions. With high time resolution, CEUS have advantages for follow-up study of benign liver lesions.
