Clinical evaluation value of multi-sequence MRI combined scanning in T staging of bladder cancer
Objective To evaluate the clinical value of multi-sequence magnetic resonance imaging(MRI)combined scanning in T staging of bladder cancer.Methods From June 2020 to June 2023,100 patients with bladder cancer were selected as observation objects for retrospective study,The enrolled patients were all admitted to our hospital.After enrolled,MRI sequential scanning,con-ventional diffusion-weight imaging(MRI+DWI)scanning,and conventonal dynanic contrast-enhance-ment(MRI+DWI+DCE)scanning were performed on the patients,respectively.The diagnostic ac-curacy of T stage and myoinfiltration under different scanning schemes was calculated.Results Among the enrolled patients,T2 phase was the most common,with a total of 39 cases(39.00％),followed by 22 cases(22.00％)in T1 phase,20 cases(20.00％)in T3 phase,and 19 cases(19.00％)in T4 phase.In terms of muscle infiltration,there were 78 cases(78.00％)with muscle infiltration and 22 cases(22.00％)without muscle infiltration.Comparing the diagnostic results of different stages and sequences of scans,the total accuracy of MRI+DWI+DCE was significantly higher than that of MRI+DWI scans and MRI sequence scans,and the differences were statistically significant[x2=21.335,36.125,all P＜0.01].In terms of the scanning effect on muscle layer infiltration,the accu-racy of MRI+DWI+DCE scanning was significantly higher than that of MRI and MRI+DWI scan-ning,and the accuracy of MRI+DWI scanning was significantly higher than that of MRI,with statisti-cal significance[77 cases(98.72％)vs.58 cases(74.36％)vs.40 cases(51.28％),all P＜0.05].In terms of diagnostic accuracy for non muscular infiltration,the accuracy of MRI+DWI+DCE scanning was significantly higher than that of MRI and MRI+DWI scanning,and the accuracy of MRI+DWI scanning was higher than that of MRI,with statistical significance[21 cases(95.45％)vs.14 cases(63.64％)vs.12 cases(54.55％),all P＜0.05].Conclusions In the process of clinical evaluation of bladder cancer patients,multi-sequence MRI combined scanning can better eval-uate the T stage of patients.
