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(χ 2=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(χ 2=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)](χ 2=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.
