Clinical value of Siemens 64 row CT and 1.5T MRI in the single or combined diagnosis of SNIP / 中国基层医药

ABSTRACT

Objective@#To compare the clinical value of Siemens 64 row CT and 1.5 T MRI in the diagnosis of sinonasal inverted papilloma (SNIP).@*Methods@#From June 2008 to June 2017, 200 patients with inverted papilloma of the nasal cavity and paranasal sinuses admitted to Lyuliang People's Hospital were selected.All patients were confirmed by surgery and pathology, and preoperative MRI and CT examination were adopted.Pathological diagnosis was taken as the gold standard for clinical diagnosis, and the coincidence rate of MRI and CT examination with pathological diagnosis was analyzed.@*Results@#The detection rate of disease stage and origin site of pathological examination was significantly higher than those of CT examination (13.00%, 35.00%, 45.00%, 7.00%, 100.00% vs.10.00%, 21.00%, 53.00%, 16.00%, 85.00%, χ2=8.273, 15.273, all P<0.05). There was no statistically significant difference in the malignant detection rate between disease detection and CT (100.00% vs.75.00%; χ2=1.923, P>0.05). There was no statistically significant difference in the detection rate of stage and origin site between the two examination methods (13.00%, 35.00%, 45.00%, 7.00%, 100.00% vs.11.00%, 37.00%, 44.00%, 8.00%, 97.00%; χ2=0.384, 2.073, all P>0.05). The malignant detection rate of pathological examination was 100%, which was significantly higher than that of MRI (100.00% vs.25.00%; χ2=9.923, P<0.05). The malignant rate of MRI examination was 25.00%, which was significantly lower than that of CT examination(χ2=4.233, P<0.05). The detection rates of stage and origin site in MRI examination were significantly higher than those in CT examination (11.00%, 37.00%, 44.00%, 8.00%, 97.00% vs.10.00%, 21.00%, 53.00%, 16.00%, 85.00%; χ2=7.384, 8.073, all P<0.05).@*Conclusion@#There are advantages and disadvantages in the early diagnosis and treatment of inverted papilloma of nasal cavity and paranasal sinuses by CT and MRI, respectively.Therefore, it is suggested that CT and 1.5T MRI should be used together.The extent of the disease and the boundary between the disease and the surrounding soft tissue are more comprehensive, which is helpful to accurately evaluate the clinical stage and origin of the tumor before operation.
