The Value of Magnetic Resonance Imaging Combined with 64-slice Spiral CT Scan in Diagnosis of Liver Cancer and Its Guiding Significance for Interventional Therapy

目的探析磁共振成像联合64层螺旋CT扫描诊断肝癌的临床价值及其对介入治疗指导意义。方法方便选取2018年1月—2019年8月在该院接受治疗的60例肝癌患者进行分组研究,随机分为CT组(n=30)与联合组(n=30)。介入治疗前,CT组患者给予64层螺旋CT诊断,联合组患者给予磁共振成像联合64层螺旋CT诊断,分析比较两组诊断结果。两组患者均给予介入治疗,CT组采用64层螺旋CT指导,联合组采用磁共振成像联合64层螺旋CT指导,对比两组治疗效果。结果CT组诊断准确率、灵敏度、特异度、阳性预测值、阴性预测值分别为80.00%、80.00%、83.33%、82.76%、80.64%,联合组诊断数据分别为96.67%、96.67%、83.33%、85.29%、96.15%,联合组诊断准确率、灵敏度、阴性预测值均显著高于CT组(χ^2=4.030、4.030、4.060,P<0.05),但两组特异度、阳性预测值比较差异无统计学意义(χ^2=0.000、0.850,P>0.05)。CT组残留动脉区强化区评分、最小直径、最大直径分别为(4.10±0.31)分、(1.46±0.22)mm、(3.43±0.23)mm,联合组数据分别为(4.11±0.35)分、(1.10±0.23)mm、(3.42±0.24)mm,联合组最小直径显著小于CT组(χ^2=5.370,P<0.05),但两组残留动脉区强化区评分、最大直径比较差异无统计学意义(χ^2=0.560、0.610,P>0.05)。结论磁共振成像联合64层螺旋CT扫描诊断肝癌的临床价值更高,且能够为介入治疗提供可靠指导。

Objective To explore the clinical value of magnetic resonance imaging combined with 64-slice spiral CT scan in the diagnosis of liver cancer and its guiding significance for interventional therapy.Methods Sixty patients with liver cancer who were treated in the hospital from January 2018 to August 2019 were convenient selected for group study and randomly divided into CT group(n=30)and combined group(n=30).Before interventional therapy,patients in the CT group were diagnosed with 64-slice spiral CT,and patients in the combined group were given magnetic resonance imaging combined with 64-slice spiral CT.The results of the two groups were analyzed and compared.Both groups of patients were given interventional therapy.The CT group was guided by 64-slice spiral CT,and the combined group was guided by magnetic resonance imaging combined with 64-slice spiral CT.The therapeutic effects of the two groups were compared.Results The diagnostic accuracy,sensitivity,specificity,positive predictive value and negative predictive value of CT group were 80.00%,80.00%,83.33%,82.76%,80.64%,and the diagnostic data of the combined group were 96.67%,96.67%,83.33%,85.29%,96.15%,the diagnostic accuracy,sensitivity,and negative predictive value of the combined group were significantly higher than the CT group(χ^2=4.030,4.030,4.060,P<0.05),but the specificity and positive predictive values of the two groups were not statistically significant different(χ^2=0.000,0.850,P>0.05).CT group residual arterial area enhancement area score,minimum diameter and maximum diameter were(4.10±0.31)points,(1.46±0.22)mm,(3.43±0.23)mm,the combined group data were(4.11±0.35)points,(1.10±0.23)mm,(3.42±0.24)mm,the minimum diameter of the combined group was significantly smaller than that of the CT group(χ^2=5.370,P<0.05),but there was no statistically significant difference in the score and maximum diameter of the residual arterial enhancement area between the two groups(χ^2=0.560,0.610,P>0.05).Conclusion Magnetic resonance imaging combined with 64-slice spiral CT scan is more valuable in the diagnosis of liver cancer,and can provide reliable guidance for interventional therapy.
