Item Diagnostic value of acustic radiation force impulse imaging in the assessment of salivary gland involvement in primary Sjogren's sydrome(2018) Haberal, Kemal Murat; Turnaoglu, Hale; Rahatli, Feride Kural; Uslu, Nihal; Pamukcu, Melih; 0000-0002-8211-4065; 0000-0002-0781-0036; 30167584; R-9398-2019Aims: The aim of this study is to investigate the diagnostic value of Acoustic Radiation Force Impulse (ARFI) imaging in the assessment of salivary gland involvement in primary Sjogren's syndrome (pSS). Material and methods: Twenty five patients with pSS and 25 healthy volunteers were included. First, echostructures and the thickness of the submandibular and parotid glands were evaluated by B-mode ultrasonography. Then, ARFI imaging with Virtual Touch Quantification (R) was performed. Ten independent shear wave velocity measurements were taken from each gland. Finally, the mean shear wave velocity (SWV) values were calculated, and used for further analysis. Results: The mean SWV values of parotid and submandibular glands were significantly higher in the pSS patients than in the healthy control group (p < 0.001). The cut-off of SWV values were calculated to be 1.98 m/s for submandibular glands, and 1.93 m/s for parotid glands. In pSS patients, the mean SWV values of parotid glands were higher than those of the submandibular glands (p < 0.001) and no statistically significant relationships between symptom duration or the degree of xerostomia and mean SWV values of parotid and submandibular glands were found (all p > 0.005). Conclusions: Our findings indicate that ARFI imaging may provide a non-invasive, simple and fast means of assessment of glandular impairment as an alternative test when other salivary gland tests are inconclusive or cannot be performed. ARFI may be a valuable adjunct for the clinical diagnosis of pSS.Item Value of shear wave elastography by virtual touch tissue imaging quantification in patients with diffuse thyroid gland pathology(2018) Haberal, Kemal Murat; Kural Rahatli, Feride; Turnaoglu, Hale; Kirnap, Nazli Gulsoy; Turhan İyidir, Ozlem; Soudmand, Aresh; Uslu, Nihal; 0000-0002-8211-4065; 30384566; R-9398-2019Background/aim: This study was performed to assess the diagnostic accuracy of shear wave elastography by virtual touch tissue imaging quantification in patients with diffuse thyroid gland pathology and to differentiate Graves' disease from Hashimoto's thyroiditis. Materials and methods: Thirty patients with Hashimoto's thyroiditis and 22 patients with Graves' disease were evaluated with conventional ultrasonography and shear wave elastography by virtual touch tissue imaging quantification. Thirty healthy participants formed the control group. Ten elastographic measurements of each thyroid lobe were performed in all three study groups. The mean shear wave velocity was calculated and compared between the patients and controls. Results: The mean shear wave velocity of the controls (1.92 +/- 0.14 m/s) was significantly lower than that of the patients with Graves' disease (2.71 +/- 0.22 m/s) and Hashimoto's thyroiditis (2.50 +/- 0.20 m/s). Patients with Graves' disease had significantly higher shear wave velocities than those with Hashimoto's thyroiditis (P < 0.001). Conclusion: Shear wave elastography by virtual touch tissue imaging quantification can be used to discriminate a normal thyroid gland from diffuse thyroid gland pathology after conventional sonography and may assist in the diagnosis of Graves' disease and Hashimoto's thyroiditis.
