Sublingual gland: MR features of normal and diseased states.

Intravoxel incoherent motion MR imaging measurements of the bilateral parotid glands at 3.0-T MR: effect of age, gender and laterality in healthy adults

“…Previous studies 6,16,17 have shown the age-related changes of several imaging-related quantitative measurements of parotid glands, including T 1 intensity ratio, CT value and peak T 2 value. They found that the T 1 intensity ratio and peak T 2 value increased, and the CT value decreased with age, and they explained that an increasing fatty content replacement of the parenchyma of the parotid gland with age might be the potential reason.…”

Magnetic resonance imaging assessment of tumorous lesions in the floor of the mouth: case reports and review of the literature

“…8 T1-weighted MR images showed an intermediate-intensity mass with peripheral high intensity, suggesting hemorrhage. T2-weighted images showed a high-intensity mass with internal septation because of 1 Ozturk, 2 Kaneda, 3 Takashima, 4 Asaumi, 4 Shelley, 12 Takagi, 13 Morita, 14 Dermoid cyst Well-defined Homogeneous to High (lipid or viscous Marked high Peripherally enhanced Desnyder, 15 De Ponte, 16 Epidermoid cyst heterogeneous material) to low Low intense wall Bloom, 17 Fuchshuber, 18 Thick low intense wall Gastrointestinal Well-defined Homogeneous Low Marked high enhanced Said-Al-Naief, 19 Chen, 20 cyst lobulated mass Kadkade, 21 Kong 22 multiple areas of hemorrhage, necrosis, calcification, and cyst formation. 8 Cavernous hemangioma was demonstrated as a lobular, septate mass with hyperintensity on T2-weighted images and a marked enhancement after administration of contrast media.…”

“…However, most reports concerning lesions involving the floor of the mouth are so-called "case presentations," and few reports have summarized the imaging features. [1][2][3][4] The "floor of the mouth" is a crescent-shaped area between the lower gingiva and the inferior surface of the tongue, formed by the suprahyoid muscles. 5 This region includes the orifice and duct of the sublingual and submandibular glands and the hypoglossal and lingual nerves; therefore, there are some difficulties or limitations in performing an excision or biopsy.…”

“…In such cases, MR examination should be performed to delineate the infiltration into deeper tissues and the permeative destruction of the jawbone. 1,5 However, there have been some difficulties in predicting the histological diagnoses for other lesions with normal mucosa, even for malignant tumors arising in the sublingual gland. 23 Therefore, it is important to clarify the image characteristics of tumescent lesions in the floor of the mouth.…”

Functional MR imaging of submandibular herniation of sublingual tissues through a gap of the mylohyoid muscle in two cases of submandibular “masses”

“…[1][2][3]. In comparison to CT and ultrasound, MRI is the most reliable imaging method in demonstrating the location and pathology of the sublingual glands [4]. Although it is pointed out in the latter paper that on T1-weighted images the hyperintense signal of the sublingual gland is less intense than fat, it is often difficult to differentiate clearly the gland from fat that is also part of the sublingual space.…”
