研究概览
简要总结
This observational research is comparative in design, that is assessing the change in qMRI measures in degenerative changes of the TMJ in patients diagnosed with DJD. These patients will be imaged multiple times over the course of 18 months, using clinical 3T MRI scanners located at the Center for Magnetic Resonance Research (CMRR), and their findings will be compared to controls; individuals who are not diagnosed with DJD. No investigational agents or MRI contrast agents will be used.
详细描述
Participants with DJD will be recruited during routine examinations at the TMD clinic located at the School of Dentistry, UMN. They will be approached by their clinicians for potential enrollment in an MRI study. Eligibility will be assessed based on prior imaging and medical history. If eligible and interested, participants will complete a consent process and a CMRR questionnaire which is a safety screening questionnaire, followed by scheduling for a 2-hour MRI session at the CMRR. During the visit, participants will undergo approximately 90 minutes of qMRI scans using a 15-channel face coil. Afterward, they'll complete an exit questionnaire. Additional follow-up scans may occur over 18 months, following the same procedures, while control participants will have two scans 1-4 weeks apart.

结局指标
主要结局
Assess the change in qMRI measures in degenerative changes of the TMJ over time
时间窗: 1.5 year
We will assess these changes between baseline MRI and multiple MRI scanning session over the course of 18 months. We will group patients who do (case group) and do not (control group) have clinical progression of DJD based on their existing CT scans and/or radiograph imaging acquired by their clinician to confirm their diagnosis. These findings will be evaluated through subjective observations and the ability to identify various anatomical structures. Additionally, intra- and inter-rater reliability analyses will be conducted to assess the consistency of the MRI interpretations
次要结局
- Build a rich MRI data set(1.5 years)
