多层螺旋CT和磁共振成像对肝细胞癌肿瘤结节的诊断价值

Diagnostic Value of Multi-slice Spiral CT and Magnetic Resonance Imaging for Tumor Nodules of Hepatocellular Carcinoma

目的探讨多层螺旋CT(MDCT)和磁共振成像(MRI)对肝细胞癌(HCC)肿瘤结节的诊断价值能力及对HCC患者治疗的影响。方法回顾性分析我院接受治疗的30例H CC患者的临床资料,所有患者均行MDCT、MRI无创伤性检查,评价MRI、CT对HCC患者肿瘤结节的数目、大小和部位进行分析。结果30例患者共检出162个肿瘤结节。MRI发现肿瘤结节(159个)VS.MDCT(123个)(P<0.001);MRI对HCC患者肿瘤结节数目总体敏感性0.97明显优于和MDCT(0.77)(P<0.05)。早期动脉期MRI诊断敏感性最好;与MDCT相比,MRI肿瘤结节直径略大[(29.24±25.08)mm VS.(24.07±22.28)mm](P<0.005)。结论增强MRI对肝癌结节的诊断优于MDCT,患者应按照专门的MRI方案进行介入或手术治疗。

Objective To explore the diagnostic value of multi-slice spiral CT(MDCT)and magnetic resonance imaging(MRI)for hepatocellular ca rcinoma(HCC)tumor nodules and their effect on the treatment of patients with HCC.Methods The clinical data of 30 patients with HCC who underwent treatment in our hospital were retrospectively analyzed.All patients underwent a non-invasive examination of M DCTCT and MRI.MRI and CT were used to analyze the number,size and location of tumor nodules in patients with HCC.Results A total of 162 tumor nodules were detected in 30 patients.MRI found tumor nodules(159)VS.MDCT(123)(P<0.001);MRI had a better overall sensitivity of 0.97 for HCC patients with tumor nodules and MDCT(0.77)(P<0.05).MRI was the most sensitive in early arterial phase diagnosis;MRI tumor nodules were slightly larger[(29.24±25.08)mm VS.(24.07±22.28)mm]than MDCT(P<0.005).Conclusion Enhanced MRI is superior to MDCT in diagnosing liver cancer nodules,and patients should be treated with intervention or surgery according to a special MRI protocol.
