Computed tomography and magnetic resonance imaging of the head and neck, 2nd edn. In particular, both high-resolution magnetic resonance imaging (hMRI) and diffusion weighted imaging (DWI) have been widely used to image tongue structure for decades due to their abilities to provide information about 3D internal muscle anatomy and fiber myoarchitecture (Gaige et al., 2007; Woo et al., 2012; Stone et al., 2014; Töger et al . The collection of 140 high-resolution images covers all major areas - neck, larynx, oropharynx, tongue, nasopharynx, skull base, sinuses, and temporal bone - displayed in sagittal, axial, and coronal MR image planes. Numerous prospective and retrospective studies have investigated various imaging methods such as orthopantomogram (OPG), CT scan, Denta scan, MRI, Bone scan and SPECT for assessing mandibular invasion in oral squamous cancers. The results show the structure, relationships and variability among the muscles, as well as the effects of age, gender and weight on muscle volume. Study Objectives: We utilized novel three-dimensional volumetric analysis techniques with magnetic resonance imaging (MRI) to study the upper airway and surrounding soft-tissue structures. mography (CT) or magnetic resonance imaging (MRI) are used for evaluation, but there may be cases where both are needed in conjunction. Oral vestibule 19. 512 anatomical structures were dynamically labeled, and some structures have been .

Magnetic resonance imaging of the tongue, oropharynx, hypopharynx, and larynx of normal subjects was accomplished and normal anatomy was demonstrated. Magnetic resonance imaging of the tongue, oropharynx, hypopharynx, and larynx of normal subjects was accomplished and normal anatomy was demonstrated. Genioglossus is the largest of all the tongue muscles and forms the bulk of the tongue. In this article, we review the normal tongue anatomy, make recommendations for the imaging of lesions of the root of the tongue, discuss the imaging features of a variety of such lesions (congenital nonvascular, congenital vascular, infectious, and benign and malignant neoplastic lesions), and address surgical management issues. (A shout-out to anaesthesiology colleagues who get birds. Thyroglossal duct cyst (TDC) is the most common congenital cystic lesion and pediatric mass in the neck. It is the most complete reference of human anatomy available on web, iPad, iPhone and android devices. Noninvasive magnetic resonance imaging (MRI) provides excellent soft tissue definition and multidirectional imaging capability. Figure 1: Tongue images are acquired in three orthogonal volumes with FOV encompassing the tongue and surrounding structures. This review article discusses the relevant anatomy, clinical highlights and the characteristic imaging features of the various pathologies that occur within the sublingual and submandibular spaces.
