Objective To assess T2-weighted imaging (T2WI), Diffusion-weighted imaging (DWI), Gradient recalled echo-In phase (IP) and Opposed phase (OP) for quantitative detection of small hepatocellular carcinomas (SHCC) in patients with hepatitis B induced cirrhosis. Methods A total of 30 hepatitis B induced cirrhotic patients with 30 SHCC which were pathologically confirmed, all underwent T2WI, DWI, IP and OP. Analyzed the manifestation of SHCC on the four sequences, measured the signal intensity (SI) of SHCC and liver parenchyma on the four sequences and the standard deviation of noise (SDnoise), compared the detection rate, SNR and CNR of SHCC on T2WI, DWI, IP and OP. Results ① There were no statistically significant difference (P>0.05) among the detection rates of T2WI, DWI, IP and OP. ② SNR: DWI>T2WI, statistically significant difference (P<0.05) could be detected; ③ The envelope and the blood supply characteristics displayed better on IP and OP. Conclusion The SNR for the detection of SHCC on DWI was the highest, which was superior to T2WI, IP and OP, the envelope and the blood supply characteristics displayed better on IP and OP.
