MRI各序列扫描肝细胞肝癌的图像特点及其与常规CT多期增强的比较

Image Characteristics of MRI Sequence Scanning for Hepatocellular Carcinoma and the Comparison with Conventional Multiphase Contrast-enhanced CT Scan

目的探究磁共振成像(MRI)各序列扫描肝细胞肝癌(HCC)的图像特点及其与常规CT多期增强的比较。方法回顾性分析我院收治的52例HCC患者的临床资料,所有患者均行MRI自旋回波序列T1WI、T2WI、脂肪抑制序列(STIR)FS横断位扫描及常规CT多期增强扫描,并经手术或穿刺病理证实,分析MRI各序列扫描特点,比较MRI与常规CT多期增强扫描对HCC的诊断价值。结果 MRIT1WI序列主要表现为稍低信号;T2WI、STIR序列以高信号为主;MRI可较好显示HCC病灶情况,对病灶诊断准确率为90.00%,多期增强CT对病灶诊断准确率为86.67%,两者比较差异无统计学意义(P>0.05)。结论 MRI可较好显示HCC病灶情况,其对病灶的诊断准确率与多期增强CT诊断价值相当,可应用于临床为HCC的治疗提供参考。

Objective To investigate the imaging characteristics of magnetic resonance imaging(MRI)sequence scanning for hepatocellular carcinoma(HCC)and the comparison with conventional multi-phase contrast-enhanced CT scan.Methods The clinical data of 52 patients with HCC in the hospital were analyzed retrospectively.All patients underwent MRI spin echo sequences T1WI,T2WI and fat suppression sequence(STIR)FS transverse scan and conventional multi-phase enhanced CT scan.Besides,they were confirmed by surgery or biopsy.The characteristics of MRI scans were analyzed.The diagnostic value of MRI and conventional multi-phase enhanced CT scan for HCC was compared.Results The MRI T1WI sequence mainly showed slightly lower signal.T2WI and STIR sequences mainly showed high signals.MRI could well show lesions of HCC and the diagnostic accuracy was 90.00%,while the diagnostic accuracy of multiphase contrast-enhanced CT was 86.67%(P>0.05).Conclusion MRI can better show the lesions of HCC,and the diagnostic accuracy is similar to that of multi-phase contrastenhanced CT,and can provide references for clinical treatment of HCC.
