SMI seems to be more sensitive than PDUS for evaluating the vascularity of the median nerve in patients with CTS, and SMI grading is correlated with the ENMG results.
SMI is more sensitive than PDI for detecting subtle blood flow in intraductal breast lesions with statistical significance. This novel and promising vascular imaging technique may be helpful in B-mode ultrasonography to distinguish intraductal breast lesions.
The combination of SMI and B-mode sonography was found to have excellent diagnostic performance for lateral epicondylosis. Neovascularzation in patients' tendons with lateral epicondylosis was identified much better with SMI compared to color or power Doppler imaging.
Polycystic ovary syndrome (PCOS), and nodular and autoimmune thyroid diseases are frequently seen disorders. Previous studies reported conflicting results regarding possible association between PCOS and thyroid disorders. In this study, we investigated the frequency of autoimmune thyroid disease (AITD) and nodular goiter in patients with PCOS. Seventy-three PCOS patients and 60 age-matched controls were enrolled in the study. In PCOS group, body mass index values (27.45 ± 5.73 vs. 22.55 ± 3.78 kg/m(2), p < 0.001, respectively), systolic [110 mmHg (90-130) vs. 100 mmHg (90-140), p = 0.016, respectively] and diastolic (72.67 ± 6.52 vs. 66.42 ± 8.88 mmHg, p < 0.001, respectively) blood pressure, waist circumference (86.27 ± 14.41 vs. 78.78 ± 8.87 cm, p < 0.001, respectively), and homeostasis model assessment-insulin resistance (HOMA-IR) levels (2.96 ± 2.11 and 1.77 ± 0.83 p < 0.001, respectively) were higher than controls. However, thyroid nodule frequency was similar in both groups [22 (30.1 %) vs. 12 (20 %)], also thyroid gland volume was not significantly different [9.23 ml (3.08-32.40) vs. 8.52 ml (4.28-50.29)] among groups. The percentages of patients with thyroid parenchymal heterogeneity, positive anti-thyroid peroxidase, anti-thyroglobulin, and AITD were similar. Cases were reclassified according to the presence of thyroid nodule in which similar HOMA-IR levels were detected (median 2.39 and 1.89, p = 0.093, respectively) despite the fact that the group with nodules had higher mean age (26.5 (18-37) vs. 21 (18-34), p = 0.013, respectively). Similar ratios of thyroid nodule and AITD were found in patients with PCOS and controls.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
