ABSTRACT
Objective To study the DCE-MRI findings of laryngeal and hypopharyngeal carcinoma.Methods 26 new patients di-agnosed laryngeal and hypopharyngeal cancer by pathology were collected and took DCE-MRI before therapy.The TIC type,ADC value,peak time (Tpeak),peak signal enhancement percentage (SERmax),positive enhancement integral(PEI),maximum slope of increase(MSI)and maximum slope of decrease(MSD)were obtained respectively.These semi-quantitative parameters of primary cancer,normal pharyngeal tissue and the same layer neck muscles were compared and P 0.05 )was found.Different b values (b = 300 s/mm2 , 500 s/mm2 )for ADC values were significantly different.There was statistical significance in semi-parameters among the primary cancer,normal pharyngeal wall tissue and the same layer neck muscles.Setting MSI value 58.32 threshold to distinguish abnormal and normal tissues,sensitivity and specificity both were 84.6%.Conclusion DCE-MRI can reflect morphology and signal differences among neck muscles,normal and abnormal laryngeal and hypopharyngeal tissues,providing help for diagnosis of primary carcino-ma.
