- Abstract
Purpose: To evaluate the value of multi-slice CT and MRI on maxillofacial region soft tissue measurement., Methods: A total of 12 cases of dentofacial orthodontic underwent X-ray photograph, multi-slice CT and MRI scanning. The angle and distance of maxillofacial region soft tissue were measured respectively. All data were analyzed statistically for ANOVA with SPSS11.0 software package., Results: There was no significant difference among the three measurement methods: X-ray photograph, multi-slice CT and MRI(P>0.05). MRI had advantages on depicting hierarchical structure of maxillofacial region, especially soft tissues, while multi-slice CT had advantages on depicting structure of maxillofacial region, both hard and soft tissues., Conclusions: Multi-slice CT and MRI are useful on maxillofacial region soft tissues measurement. MRI is superior to multi-slice CT and X-ray photograph on maxillofacial region soft tissue measurement.
