磁共振成像(MRI)检查常用于颞颌关节紊乱症的诊断。然而关于(magnetic resonance imagen,MRI)能否确定颞颌关节盘及关节盘后组织的内部改变的研究却很少。为了评估颞颌关节盘手术之前MRI检查的价值,作者对11位颞颌关节盘移位但无穿孔的慢性颞颌关节紊乱症患者术前MRI检查结果和术后病理检查结果进行了比较研究。 材料和方法 采用三维快速成像的稳态进动序列(FISP-3D,three-dimensional fast imaging with a steady precession squence)技术对11名颞颌关节盘移位但无穿孔的慢性颞颌关节紊乱患者和30名无症状的志愿者进行MRI检查。11名患者中男性2名,女性9名,平
Magnetic resonance imaging (MRI) commonly used in the diagnosis of temporomandibular joint disorders. However, few studies are available on whether magnetic resonance imaging (MRI) can determine the internal changes of the temporomandibular joint discs and the posterior commissural tissues. To evaluate the value of MRI before temporomandibular joint disc surgery, we compared the preoperative MRI findings and postoperative pathological findings of 11 patients with temporomandibular joint disorder who underwent TMJ disc displacement without perforation. Materials and Methods 11 patients with chronic temporomandibular joint disorder who had TMJ disc displacement but no perforation were treated with three-dimensional fast imaging with a steady precession sequence (FISP-3D) Thirty asymptomatic volunteers underwent MRI. Among the 11 patients, 2 were males and 9 were females
