磁共振成像与增强CT扫描用于肝癌诊断的价值比较

中国基层医药, 2020,27(23) : 2817-2820. DOI: 10.3760/cma.j.issn.1008-6706.2020.23.001

摘要

目的

比较磁共振成像(MRI)与增强CT扫描用于肝癌诊断的价值。

方法

选取余姚市人民医院2017年1-12月诊治的肝癌患者72例为研究对象，分别采用肝脏增强CT扫描与MRI扫描，比较两种检查方式对病灶的阳性率、准确率及两种检查方式的敏感性、特异性。

结果

两种检查方式对肝外病灶的检出情况(41.67%比36.11%)差异无统计学意义(P>0.05)；MRI肝内病灶检出率(94.44%)显著高于增强CT(77.78%)(χ²＝8.361，P<0.05)；MRI的漏诊率[5.56%(4/72)]、误诊率[1.39%(1/72)]均低于增强CT组[22.22%(16/72)、11.11%(8/72)]，准确率[93.06%(67/72)]高于增强CT[66.67%(48/72)]，差异均有统计学意义(χ²＝8.361、4.354、15.578，均P<0.05)；MRI的敏感性[92.86%(52/56)]、特异性[93.75%(15/16)]均高于增强CT[71.43%(40/56)、50.00%(8/16)](χ²＝8.675、7.575，均P<0.05)。

结论

MRI用于肝癌患者的诊断，准确率、敏感性、特异性均高于增强CT。

肝癌是消化系统常见的恶性肿瘤^[1]，患者在发病之后若不能进行及时有效的治疗，则会导致肝癌破裂出血、上消化道出血以及肝功能衰竭等的严重并发症，从而促使患者病情加重，对患者的身体健康以及生命安全产生严重影响^[2,3]。研究表明，大部分肝癌患者在就诊时就被确定为晚期，并且对其进行早期治疗与患者的预后情况紧密相连。因此，有效的提升患者早期诊断的检出率及准确率对患者预后具有至关重要的作用^[4,5]。本研究比较磁共振成像(MRI)与增强CT扫描用于肝癌诊断的价值。现报告如下。

Abstract

Objective

To compare the clinical value of magnetic resonance imaging (MRI) and enhanced CT in the diagnosis of liver cancer.

Methods

From January 2017 to December 2017, 72 patients with liver neoplasms who received treatment in Yuyao People's Hospital were selected as the subjects of this study.Enhanced CT scan and liver MRI scan were used in all patients respectively to compare the examination conditions of the two scanning methods for the lesions, the positive rate and accuracy of the detection, as well as the sensitivity and specificity of the two methods.

Results

There was no statistically significant difference in the detection of extrahepatic lesions between the two methods(41.67% vs.36.11%, P>0.05). The detective rate of intrahepatic lesions of MRI (94.44%) was higher than that of enhanced CT(77.78%), the difference was statistically significant(χ²=8.361, P<0.05). The missed diagnosis rate[5.56%(4/72)], misdiagnosis rate[1.39%(1/72)] of MRI were lower than those of enhanced CT[22.22%(16/72), 11.11%( 8/72)], and the accuracy of MRI[93.06%(67/72)] was higher than that of enhanced CT[66.67%(48/72)], the differences were statistically significant(χ²=8.361, 4.354, 15.587, all P<0.05). The sensitivity[92.86%(52/56)], specificity[93.75%(15/16)] of MRI were higher than those of enhanced CT[71.43%(40/56), 50.00%(8/16)](χ²=8.675, 7.575, all P<0.05).

Conclusion

In the clinical diagnosis of liver cancer, the diagnostic accuracy of liver MRI is relatively high, which is conducive to the establishment and implementation of patients' treatment plan, and is conducive to clinical application and promotion.
