“…Strain elastography is inexpensive, easy to use, noninvasive, takes a short time, and has no adverse effects compared to other prominent methods of medical imaging. However, few studies 11 in the literature have investigated the use of intraoral ultrasonography with strain elastography for tongue carcinoma. Therefore, the aim of this study was to investigate the strain elastography of tongue carcinoma using intraoral ultrasonography, with a special focus on conducting a preliminary study for characterizing normal tissues and lesions.…”

“…Acu et al 3 reported that ultrasound elastography added no additional value to combined B-mode and color Doppler sonography for differentiating between benign and malignant cervical lymph nodes. Shingaki et al 11 showed that intraoral strain elastography could be an alternative noninvasive method for diagnosing tongue carcinoma. In this study, we present findings regarding the quantitative strain elastography of tongue carcinoma using intraoral ultrasonography.…”

PurposeThe aim of this study was to evaluate the quantitative strain elastography of tongue carcinoma using intraoral ultrasonography.Materials and MethodsTwo patients with squamous cell carcinoma (SCC) who underwent quantitative strain elastography for the diagnosis of tongue lesions using intraoral ultrasonography were included in this prospective study. Strain elastography was performed using a linear 14 MHz transducer (Aplio 300; Canon Medical Systems, Otawara, Japan). Manual light compression and decompression of the tongue by the transducer was performed to achieve optimal and consistent color coding. The variation in tissue strain over time caused by the compression exerted using the probe was displayed as a strain graph. The integrated strain elastography software allowed the operator to place circular regions of interest (ROIs) of various diameters within the elastography window, and automatically displayed quantitative strain (%) for each ROI. Quantitative indices of the strain (%) were measured for normal tissues and lesions in the tongue.ResultsThe average strain of normal tissue and tongue SCC in a 50-year-old man was 1.468% and 0.000%, respectively. The average strain of normal tissue and tongue SCC in a 59-year-old man was 1.007% and 0.000%, respectively.ConclusionWe investigated the quantitative strain elastography of tongue carcinoma using intraoral ultrasonography. Strain elastography using intraoral ultrasonography is a promising technique for characterizing and differentiating normal tissues and SCC in the tongue.

“…Furthermore, ultrasound elastography, a technique first described in the 1990s, has recently been used to provide qualitative and quantitative assessment of tissue stiffness (e.g., Shiina et al 2015; for review, see Gennisson et al 2013;Sigrist et al 2017). It has also been used to measure mechanical properties of musculoskeletal tissue in clinical practice (Drakonaki 2012;Drakonaki et al 2012), and to diagnose tongue carcinoma in a preliminary study (Shingaki et al 2017). A pilot study recently examined the use of ultrasound elastography to evaluate mechanical characteristics and textures of gels (Gao et al 2016), which has been found to have an elastic property similar to that of the human tongue.…”

The tongue makes up the anterior pharyngeal wall and is critical for airway patency. Magnetic resonance imaging (MRI) is commonly used to study pharyngeal muscle function in pharyngeal disorders such as obstructive sleep apnoea. Tagged MRI and ultrasound studies have separately revealed »1 mm of anterior tongue movement during inspiration in healthy patients, but these modalities have not been directly compared. In the study described here, agreement between ultrasound and MRI in measuring regional tongue displacement in 21 healthy patients and 21 patients with obstructive sleep apnoea was evaluated. We found good consistency and agreement between the two techniques, with an intra-class correlation coefficient of 0.79 (95% confidence interval: 0.75À0.82) for anteroposterior tongue motion during inspiration. Ultrasound measurements of posterior tongue displacement were 0.24 § 0.64 mm greater than MRI measurements (95% limits of agreement: 1.03 to À1.49). This may reflect the higher spatial and temporal resolution of the ultrasound technique. This study confirms that ultrasound is a suitable method for quantifying inspiratory tongue movement.

PurposeTo evaluate the usefulness of shear wave elastography in the diagnosis of oral and maxillofacial diseases.Materials and MethodsTen patients with oral and maxillofacial diseases and 28 volunteers drawn from our student doctors were examined by shear wave elastography with a 14-MHz linear transducer using an Aplio 300 apparatus (Canon Medical Systems, Otawara, Japan). A statistical analysis of the shear elastic modulus (kPa) of healthy tissue (the sublingual gland, submandibular gland, anterior belly of the digastric muscle, and geniohyoid muscle) in the 28 volunteers was performed using 1-way repeated measures analysis of variance with the Tukey honest significant difference test. The maximum shear elastic modulus (kPa) of 8 patients with squamous cell carcinoma (SCC) and 2 patients with benign lesions was evaluated with the Mann-Whitney U test. The analysis used a 5% significance level.ResultsThe mean shear elastic modulus of the sublingual gland (9.4±3.7 kPa) was lower than that of the geniohyoid muscle (19.2±9.2 kPa, P=.000) and the anterior belly of the digastric muscle (15.3±6.1 kPa, P=.004). The maximum shear elastic modulus of the SCCs (109.6±14.4 kPa) was higher than that of the benign lesions (46.4±26.8 kPa, P=.044).ConclusionOur results demonstrated the usefulness of shear wave elastography in the diagnosis of oral and maxillofacial diseases. Shear wave elastography has the potential to be an effective technique for the objective and quantitative diagnosis of oral and maxillofacial diseases.
