Abstract:
Objective To evaluate the clinical value of multi-tomographic imaging mode of three-dimensional ultrasound combined with surface imaging in diagnosing and staging bladder tumors.Methods Seventy-five patients were examined with three-dimensional ultrasound and two-dimensional ultrasound.In addition,54 cases were undergone preoperative multislice spiral CT.All cases were proved by pathology after operation.Results The qualitation accuracy in the diagnosis of bladder tumor with two-dimensional ultrasound was 93.3%(70/75) and that of three-dimensional ultrasound was 98.7%(74/75).The staging accuracy rates with two-dimensional ultrasound and three-dimensional ultrasound were 83.5%(106/127) and 93.2%(123/132) respectively.The difference of bladder tumor staging between three-dimensional ultrasound and two-dimensional ultrasound was significant (P＜0.05).The qualitation accuracy in the diagnosis of bladder tumor with CT was 90.7%(49/54).The preoperative staging rate of CT was 79.7%(59/74),compared with that of three-dimensional ultrasound,the difference was significant(P＜0.05).Conclusions Multi-tomographic imaging mode of three-dimensional ultrasound combined with surface imaging can provide useful information and makes an improvement in detecting and staging bladder tumors.
