Application Value of MRI and Multi-slice Spiral CT in the Diagnosis and Preoperative Staging of Laryngeal Cancer
Objective To explore the application value of magnetic resonance imaging(MRI)and multi-slice spiral CT in the diagnosis and preoperative staging of laryngeal cancer.Methods The clinical data of 173 patients with suspected laryngeal cancer who received MRI and multi-slice spiral CT in our hospital were retrospectively analyzed from February 2020 to November 2023.Pathological examination was used as the gold standard for diagnosis to analyze the diagnostic efficiency of MRI and multi-slice spiral CT on laryngeal cancer.Based on the clinical staging results of pathological examination,the patients with laryngeal cancer were grouped,and the accuracy of MRI and multi-slice spiral CT in the clinical staging diagnosis of laryngeal cancer was compared.Results Pathological examination showed that 110 of the 173 patients with suspected laryngeal cancer were confirmed.The Kappa values of MRI and MSCT in the diagnosis of laryngeal cancer were 0.712 and 0.196 respectively.The pathological preoperative staging of 110 patients with laryngeal cancer revealed T1 stage in 18 cases,T2 stage in 32 cases,T3 stage in 37 cases and T4 stage in 23 cases.The accuracy rates of MRI and MSCT in preoperative staging evaluation of laryngeal cancer were 87.27％(96/110)and 72.73％(80/110)respectively.Conclusion Compared with multi-slice spiral CT,MRI has higher diagnostic efficiency on patients with laryngeal cancer.MRI is helpful for preoperative staging and provides direction for clinical treatment,and has high application value.
