Purpose: The value of virtual touch tissue imaging (VTI) with support of Image-Pro Plus (IPP) for diagnosing malignant thyroid tumors was assessed in the present study.
Methods: In this retrospective study, we enrolled 160 patients with 198 thyroid nodules. TI-RADS, VTI grade, and VTI with support of IPP (VTI-IPP) were underwent for each nodule. With the pathological diagnosis as the gold standard, the receiver-operating characteristic curve (ROC) was drawn to evaluate the diagnostic performance of VTI-IPP, VTI, TI-RADS, VTI-IPP combinate with TI-RADS in thyroid carcinoma.
Results: VTI-IPP score >2, VTI score >3, TI-RADS score >1, and VTI-IPP combine with TI-RADS score >4 expressed the highest diagnostic value for malignant thyroid nodules, the areas under the curve (AUC) were 0.939, 0.905, 0.925, and 0.967, respectively. The combination indicated the largest AUC, compared with VTI-IPP and TI-RADS, respectively (P = 0.0054 and 0.0009). The performance of VTI-IPP in diagnosing thyroid carcinomas was better than VTI (P = 0.0321).
Conclusion: Compare with VTI, VTI-IPP exhibited more excellent value in distinguishing between benign and malignant thyroid nodules. The value of malignant thyroid nodules diagnosis can be improved when VTI-IPP combines with TI-RADS.

Objectives: incidental thyroid nodules (ITNs) are found in up to 25% of CT scans. Increased use of cross-sectional imaging has contributed to the increased incidence of thyroid cancer worldwide. ITNs pose a management dilemma since nodule malignancy rate is 5-15% but most cancers are indolent and prognosis in differentiated thyroid cancer is excellent.

Cytologically indeterminate thyroid nodules (Bethesda class III or IV) carry a 10-40% risk of malignancy. Diagnostic lobectomies are frequently performed but negative surgeries incur unnecessary costs on the healthcare system, potential complications, and negative impacts on quality of life. Molecular tests (MTs) have been developed to reduce unnecessary surgeries.

Background Thyroid nodules are typically an initial sign of thyroid cancer (TC) and require evaluation by thyroid ultrasonography. Additional measures, such as fine needle aspiration, may be necessary depending on the level of malignancy risk. This study aims to comprehensively analyze TC clinical, radiological, and histopathological characteristics in a cohort of Saudi patients.

Introduction: The interplay between emotional disorders and thyroid disorders has been subject to numerous observational studies, which have consistently reported associations but have failed to establish clear causal links due to the multifactorial etiology and influences. We conducted a bidirectional two-sample Mendelian randomization (MR) analysis to explore the genetic causal association between emotional disorders and thyroid disorders.
Methods: We employed several methods, including inverse-variance weighted (IVW), weighted median, weighted mode, and MR Egger regression.
