[Evaluation of dynamic enhanced fast multiplanar spoiling gradient recalled(FMPSPGR) in the diagnosis of small hepatocellular carcinoma].
OBJECTIVE
To analyze the features of small hepotocellular carcinoma (SHCC) by spin echo (SE) sequence and dynamic enhanced FMPSPGR, and to compare the sensitivity for detecting and the accuracy for characterization, further to discuss the value of FMPSPGR in the diagnosis of SHCC.


METHODS
SE T(1)WI, T(2)WI and FMPSPGR dynamic imaging of the liver were performed for 58 patients with SHCC. The sensitivity for detecting and accuracy for characterization were statistically compared.


RESULTS
Seventy-two lesions were found in 58 patients. In the detection of SHCC, the order of the sensitivity was dynamic enhanced FMPSPGR>SE T(2)WI>no-enhanced FMPSPGR>SE T(1)WI. Dynamic enhanced FMPSPGR was significantly higher than any of the others. There was significant difference between no-enhanced FMPSPGR and SE T(2)WI, but not significant difference between T(2)WI and no-enhanced FMPSPGR. In the characterization of SHCC, the accuracy of pre- and post-contrast FMPSPGR was significantly higher than that of SE (T(1)WI+T(2)WI) with remarkable statistical difference.


CONCLUSIONS
FMPSPGR dynamic imaging is superior to SE in the detection and characterization of SHCC. The sensitivity for detecting and the accuracy for characterization will be improved when both FMPSPGR and SE are used.
