Normal and abnormal temporomandibular joint: MR imaging with surface coil
Radiology
|January 1, 1986
Summary
Magnetic resonance (MR) imaging with a surface coil accurately depicts normal and abnormal temporomandibular joints (TMJ). This noninvasive technique offers detailed insights into meniscal condition, surpassing conventional methods for TMJ diagnosis.
Area of Science:
- Radiology
- Medical Imaging
- Orthopedics
Background:
- Temporomandibular joint (TMJ) disorders are common.
- Accurate diagnosis is crucial for effective treatment.
- Conventional imaging modalities have limitations.
Purpose of the Study:
- To evaluate the efficacy of magnetic resonance (MR) imaging with a surface coil for diagnosing temporomandibular joint (TMJ) abnormalities.
- To compare MR imaging findings with arthrography, computed tomography (CT), and surgical outcomes.
Main Methods:
- MR imaging was performed on 5 normal TMJs and 37 abnormal TMJs (76 total) using a 1.5-T system and surface coil.
- Multisection sagittal, coronal, and axial images were acquired using partial saturation and spin-echo sequences.
- MR findings were compared with arthrography, CT, and surgical data.
Main Results:
- MR imaging with a surface coil accurately depicted both normal and abnormal TMJs.
- MR provided detailed information on meniscal position, morphology, and histology.
- This information was superior to that obtained with arthrography or CT alone.
Conclusions:
- MR imaging with a surface coil is a highly accurate and noninvasive modality for TMJ evaluation.
- It offers superior diagnostic information compared to conventional methods.
- Further research is warranted to establish MR imaging as a primary tool for TMJ pain and dysfunction diagnosis.
