“…High-resolution MR images from Tokyo Dental College, Chiba, Japan As in [23,24], the method was demonstrated for high-resolution MR-imaging carried out using a 1.5-T MRI scanner system (Magnetom Symphony Maestro Class, Siemens, Erlangen, Germany) with the use of bilateral surface coils, "Double Loop Array," as receivers. Oblique sagittal crosssectional plane images oriented according to the individual angle of the mandibular condyle were obtained, at closed and open mouth position (Fig.…”

Objective An approach of 3D-visualization of the temporomandibular joint (TMJ) with special focus on the articular disc based on magnetic resonance imaging (MRI) was developed for the purpose of diagnosis support. Materials and methods Mandibular condyle and fossa were reconstructed as 3D-surfaces. Articular disc, retrocondylar tissue, and the lateral pterygoid muscle were visualized by means of direct volume rendering. By simultaneous visualization of both, the bony surfaces and the soft tissue, anterior disc displacement could be recognized in 3D-context. Additional superposition of the 3D-visualization with the original 2D-MRI slices allowed for a combination with conventional diagnostics. The method was tested for clinical T1-, T2-, and This paper has been written on behalf of a publication request following Cars proton density weighted MRI data from four independent medical institutions. Results For all cases, the skeletal anatomy could be reproduced. Applied validation approaches showed good results. Anterior disc displacement could be clearly depicted as well as the incidence of reduction of the disc. By several experienced observers, the approach was rated as significant. Conclusion Although partially non-standard in the clinical routine the new method provided promising results for efficient diagnosis support. Its validity in the medical practice, namely, its impact for dislocation/deformity of the mandibular disc will be further analyzed.

“…The focus was put on anterior disc displacement with and without reduction. The present study is an extension of the results presented in [23,24] where a first version of the approach was tested for a case based on high-resolution MR images from Tokyo Dental College.…”

“…8,9 A dual echo technique is generally used for 2-dimensional (2D)-PDWI and -T 2 WI scans. 10 Sagittal and coronal sections of the TMJ in both closed-and opened-mouth positions are also required to determine displacement and reduction of the articular disk. 11,12 However, 2D dual echo imaging is often technically di‹cult for planning.…”

Purpose: We investigated the ability to detect the articular disk and joint eŠusion of the temporomandibular joint (TMJ) of a method of dual echo volumetric isotropic turbo spin echo acquisition (DE-VISTA) additional fusion images (AFI).Methods: DE-VISTA was performed in the 26 TMJ of 13 volunteers and 26 TMJ of 13 patients. Two-dimensional (2D) dual echo turbo spin echo was performed in the 26 TMJ of 13 volunteers. On a workstation, we added proton density-weighted images (PDWI) and T 2 weighted images (T 2 WI) of the DE-VISTA per voxel to reconstruct DE-VISTA-AFI. Two radiologists reviewed these images visually and quantitatively.Results: Visual evaluation of the articular disk was equivalent between DE-VISTA-AFI and 2D-PDWI. The sliding thin-slab multiplanar reformation (MPR) method of DE-VISTA-AFI could detect all articular disks. The ratio of contrast (CR) of adipose tissue by the articular disk to that of the articular disk itself was signiˆcantly higher in DE-VISTA-AFI than DE-VISTA-PDWI (Pº0.05) in patients and volunteers with closed or open mouth. In volunteers, the CR between adipose tissue and the disk on DE-VISTA-AFI was marginally signiˆcant to that on 2D-PDWI at opened mouth (P＝0.071) and not signiˆcantly diŠerent (P＝0.18) from that at closed mouth. Joint eŠusion could be identiˆed in DE-VISTA-AFI in all 8 joints that had joint eŠusion in DE-VISTA-T 2 WI but in only 3 of those joints in 2D-T 2 WI. The CR of joint eŠusion to adipose tissue on DE-VISTA-AFI did not diŠer signiˆcantly from that on DE-VISTA-PDWI. However, using DE-VISTA-T 2 WI in addition to DE-VISTA-PDWI, we could visually identify joint eŠusion on DE-VISTA-AFI that could not be identiˆed on DE-VISTA-PDWI alone.Conclusion: DE-VISTA-AFI can depict the articular disk and a small amount of joint eŠusion by the required plane of MPR using the sliding thin-slab MPR method.

“…So far cine/near-real-time MRI research was focused on and was developed for temporomandibular joint and swallowing [4,[11][12][13]. Simultaneously to these endeavours [4,14] some progress was achieved in the field of ocular dynamic MRI. Recent studies used a cine sequence and patients were asked to fixate on single numbered marks [15].…”

Near-real time oculodynamic MRI: a feasibility study for evaluation of diplopia in comparison with clinical testing

Od-MRI is a feasible technique. Visualization of the horizontal/vertical rectus muscles is better than for the superior/inferior oblique muscle. Od-MRI correlates well with clinical testing and may reproduce the extent of eye bulb motility and extraocular muscle structural or functional deteriorations. Key Points • Oculodynamic MRI technique helps clinicians to assess eye bulb motility disorders • MRI evaluation of eye movement provides functional information in cases of diplopia • Oculodynamic MRI reproduces excursion of extraocular muscles with good correlation with clinical testing • Dynamic MRI sequence supplements static orbital protocol for evaluation of motility disorders.
