- W2378275382 abstract "Objective: To investigate clinical application value of MRI magnetic diffusion weighted imaging( DWI) and MRI dynamic contrast enhancement( DCE-MRI) to diagnose nasopharyngeal carcinoma( NPC) invading slope. Methods: Ninety-three patients with nasopharyngeal carcinoma and 16 healthy volunteers were divided into healthy slope group( group A),slope invasion group( group B)and slope change after radiotherapy group( group C); testing DWI( ADC values) and DCE-MRI parameters( including SI%,PV,TTP and TIC curve); assessing the function of ADC and DCE value in diagnosing slope invasion. Results: ADC,SI% and PV values of group B were higher than group A and group C,differences were statistically significant( P 0. 05),TTP value of group C was higher than that of group A and group B,differences were statistically significant( P 0. 05); Group A mainly presented TIC I type curve,group C presented type I and III curve,group B presented type IV and V curve; premium thresholds in diagnosing NPC patients with slope invasion were ADC values 0. 45 ×10- 3mm2/ s,TIC curve as type IV and V,SI% 121. 1,PV 1 050,TTP 92. 5. DWI( ADC values) and DCE-MRI for diagnosing slope invasion: DCE-MRI sensitivity was equal to DWI,DCE-MRI was more accurate than DWI. Conclusions: DWI and DCE-MRI are more accurate and sensitive in diagnosing nasopharyngeal carcinoma( NPC) invading slope,combined diagnosing will be more effective." @default.
