Abstract

Abstract: PURPOSE: To compare the difference of signal density ratio between condyle and brain parenchyma in normal temporomandibular joint (TMJ) structure and patients with anterior disc displacement and condylar absorption, and to explore the quantitative measurement method of condylar absorption. METHODS: From July 2018 to July 2019, 22-25 year-old women who underwent MRI examination of TMJ were collected and divided into two groups: normal joint group and condylar absorption group. A total of 40 joints in the 2 groups were measured independently by 2 investigators, and the consistency between the 2 measurers was compared. The differences of MSI1/MSI2 between the 2 groups were compared. SPSS 23.0 software package was used for statistical analysis. RESULTS: There was a high degree of consistency from the 2 investigators. At the same time, there was significant difference between the 2 groups in the ratio of condylar signal density to brain parenchyma. The mean value of MSI1/MSI2 was 1.07 in normal joint group, and 0.78 in condylar resorption group(P<0.05). CONCLUSIONS: MSI1/MSI2 may be an objective index to evaluate the severity of condylar lesions by using standardized TMJ MRI shooting process.
