Abstract:
Purpose:To explore the value of MSCT-3D in stomatology through comparing with COPT.Materials and Methods:Both MSCT 117 patients and COPT 117 patients in stomatology were selected at a particular period,COPT imaging was using computed post-processing,MSCT imaging was processed according to 3D information through work station,then to analyze the imaging results according to metal tooth、damaged tooth and broken tooth,later to compare the photograph 、the technique of computed post-processing、the photograph condition and exposure of MSCT and COPT.Results:Normal COPT patients were 9 cases ( 0.24% ),normal teeth were 3160 (84.4% ),unusual teeth were 551 (15.6%),normal MSCT-3D patients were llcases ( 0.29% ),normal teeth were 3138 (83.8% ),and unusual teeth were 606 (16.2% ).COPT belonged to COPT photograph,the emphasis was 2D,MSCT-3D belonged to spiral photograph,the emphasis was 3D,and MSCT imaging could be processed according to 3D reformation.The 3D effect of MSCT was batter than that of COPT.The radiation dosage was much higher than that of COPT.Conclusions: COPT could get 2D effects: MSCT-3D could improve 3D results on 2D basis,but the radiation dosage of MSCT is much higher than that of COPT in stomatology.
