“…Elastography images, according to the different levels of strain, were displayed on the picture over a grayscale background in a color diagram that included the colors red (softest component), green (intermediate stiffness), and blue (hardest component). 4,5 SE patterns of the cartilages of all participants were interpreted by two radiologists with a common consensus. The SE color mappings of the cartilages were divided into four types: type I, predominantly blue (hardest tissue; ►Fig.…”

We investigated the sonoelastographic features of the lower lateral nasal cartilage lateral crus (LLNC-LC), auricular conchal cartilage (ACC), and costal cartilage (CC). In this prospective study, group 1 consisted of 60 participants (30 males and 30 females) between 18 and 35 years of age. Group 2 consisted of 60 participants (30 males and 30 females) between 35 and 50 years of age. Strain elastography (SE) and shear wave elastography (SWE) were performed. For all LLNC-LCs and ACCs, type I SE was detected more in group 2, type II SE was detected more in group 1, and type III SE was detected more in group 1 (p < 0.05). For CC, type I SE was detected more in both groups (p < 0.05). For LLNC-LC, type I SE was detected more in males compared with females in both groups (p < 0.05). For all LLNC-LC, ACC and CC, the SWE modulus of group 2 was significantly higher than that of group 1 (p < 0.05). In older participants, the SWE modulus increased. We recommend using ACC mainly in rhinoplasty operations for primary and revision cases as its SWE modulus is similar to that of the LLNC-LC. However, due to the higher SWE modulus of CC, CC grafts should not be used as the first choice in rhinoplasties, especially in the reconstruction of the nasal tip contour, but may be used in nasal dorsum augmentation.

Objectives To investigate the optic nerve's elastic properties using shear wave and strain elastography in patients with migraine compared to healthy individuals. Methods The migraine group consisted of 30 patients (16 with visual auras and 14 without auras) who had previously had a diagnosis of migraine. These were age and sex matched with healthy participants to form the control group. The findings from shear wave and strain elastography in the groups were compared. The elastographic examination was performed with a 6–15‐MHz multifrequency linear array transducer. Results The evaluation involved 30 patients with migraine (3 male and 27 female), whose mean age ± SD was 34.63 ± 10 years, and 30 healthy participants (3 males, 27 females), whose mean age was 36.4 ± 10.5 years. In strain elasticity patterns, a statistically insignificant hardening of the optic nerve in the patients with migraine was observed (P = .052). Analysis of the shear wave elastic modulus values (9.8 ± 3.34 and 12.3 ± 5.25 kPa; P = .03) revealed that differences between the healthy participants and patients with migraine were statistically significant. The results for elasticity patterns and the shear modulus suggested that the differences between migraines with and without visual auras were insignificant (P > .05). A positive correlation was discovered between the duration of the disease and the shear modulus in the patients with migraine (r = 0.496; P < .01). Conclusions Histopathologic changes in the optic nerve may be seen in patients with migraine due to possible fibrotic changes. Elastographic techniques can be useful diagnostic tools for investigating these changes.

Aim In this study, we aimed to compare the strain (SE) and shear wave elastography (SWE) findings of the quadriceps tendons (QT) of the patients with chronic kidney disease (CKD) and healthy volunteers (HV), and estimate the reliability of the evaluations. Materials and Methods Twenty‐nine HV and twenty‐seven patients with CKD were enrolled. All sonoelastographic examinations were performed separately by two observers. The QT thickness (QTT), SWE, and SE findings including the tissue elastic modulus (EM), shear wave velocity (SWV), and the elasticity patterns were obtained and compared. Interobserver agreement was evaluated to test the reliability of the findings. Results The QT in CKD patients is thinner than HV (p = 0.001 for both observers). The elasticity patterns of QT were mostly intermediate stiffness for both observers (p < 0.05 for both observers). The mean EM values in the patient group were significantly higher than HV for both observers (p < 0.05 for both observers). The mean SWVs were significantly higher in the patient group (p < 0.05 for both observers). SWV showed weak, significant, and negative correlations with the hemodialysis (HD) duration (p < 0.05 for both observers). The interobserver agreements were moderate to excellent for QTT, EM, SWS, and SE patterns (p < 0.01 for all parameters). Conclusion QTT and its elasticity are decreased in patients with CKD. The QTT and SE patterns may be the choice to determine the elasticity in CKD patients with good reliability values rather than SWE. But, there is still debate on the reliability of sonoelastographic findings, to ensure standardization of the factors affecting reliability, they should be well understood.
