摘要
目的 分析小肝癌（ｓｍａｌｌ ｈｅｐａｔｏｃｅｌｌｕｌａｒ ｃａｒｃｉｎｏｍａ， ＳＨＣＣ）在自旋回波（ＳＥ）序列和快速多层面干扰梯度回波（ｆａｓｔ ｍｕｌｔｉｐｌａｎａｒ ｓｐｏｉｌｉｎｇ ｇｒａｄｉｅｎｔ ｒｅｃａｌｌｅｄ， ＦＭＰＳＰＧＲ）序列动态增强扫描中的特征，比较两者对病灶检出敏感性，进一步探讨ＦＭＰＳＰＧＲ在ＳＨＣＣ诊断中的价值。方法５８例ＳＨＣＣ病例行ＳＥ序列Ｔ１ＷＩ，Ｔ２ＷＩ和ＦＭＰＳＰＧＲ动态增强，比较其检出敏感性和定性准确性，并做统计学处理。结果５８例共检出病灶７２个，对ＳＨＣＣ的敏感性依次为ＦＭＰＳＰＧＲ增强＞ ＳＥ Ｔ２ＷＩ＞ ＦＭＰＳＰＧＲ平扫＞ ＳＥ Ｔ１ＷＩ， ＦＭＰＳＰＧＲ增强和后两者之间均有差异，而Ｔ２ＷＩ和ＦＭＰＳＰＧＲ平扫无差异，ＦＭＰＳＰＧＲ平扫和Ｔ１ＷＩ也有差异，对病灶的定性准确性，ＦＭＰＳＰＧＲ（平扫＋增强）＞ ＳＥ（Ｔ１ＷＩ＋ Ｔ２ＷＩ），两者差异有显著性。结论 ＦＭＰＳＰＧＲ序列在病灶检出和定性方面均优于ＳＥ序列，可基本取代之，两者结合可进一步提高敏感性和定性准确性。
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 T1WI, T2WI 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 T2WI>no-enhanced FMPSPGR>SE T1WI. Dynamic enhanced FMPSPGR was significantly higher than any of the others. There was significant difference between no-enhanced FMPSPGR and SE T2WI, but not significant difference between T2WI and no-enhanced FMPSPGR. In the characterization of SHCC, the accuracy of pre- and post-contrast FMPSPGR was significantly higher than that of SE (T1WI+ T2WI) 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.
