Diagnostic value and risk factors of multislice spiral computed tomography in gastrointestinal stromal tumor / 中国现代医生

ABSTRACT

@#Objective To investigate the diagnostic value and risk of gastrointestinal stromal tumors(GIST)by multislice spiral computed tomography(MSCT).Methods A total of 118 suspected GIST patients admitted to Huzhou Central Hospital from June 2021 to November 2022 were selected for MSCT examination and pathological examination.Taking pathological diagnosis as the gold standard,the efficacy of MSCT in diagnosing GIST was analyzed.Multifactor analysis was used to investigate the factors affecting the risk of GIST.Results Pathological diagnosis of GIST was confirmed in 103 of 118 suspected patients.The sensitivity,specificity and accuracy of MSCT diagnosis of GIST were 97.09%,86.67%and 95.76%,respectively.There were significant differences in maximum tumor diameter,tumor shape,tumor boundary,tumor density,cystic necrosis and fat space between high-risk group and low-risk group(P<0.05).The results of multifactor analysis showed that maximum tumor diameter,tumor shape,tumor density and fat space were all factors affecting the risk of GIST(P<0.05).Conclusion MSCT has a high accuracy in the diagnosis of GIST.The maximum tumor diameter,tumor shape,tumor density and fat space are all factors affecting the risk of GIST.
