OBJECTIVE This study aimed to investigate the characteristics of suspicious thyroid nodules of different pathological types on contrast-enhanced ultrasound (CEUS) with quantitative analysis software (Qlab). METHODS A total of 101 suspicious thyroid nodules were recruited from 90 adult patients undergoing ultrasound (US), CEUS and fine-needle aspiration cytology (FNCA). The CEUS characteristic...

It has been recognized for nearly 80 years that insoluble aluminum salts are good immunologic adjuvants and that they form long-lived nodules in vivo. Nodule formation has long been presumed to be central for adjuvant activity by providing an antigen depot, but the composition and function of these nodules is poorly understood. We show here that aluminum salt nodules formed within hours of inje...

BACKGROUND AND PURPOSE No study has previously examined the feasibility of using EA to remove any peripherally located, solid components remaining after treatment of benign solid thyroid nodules by RFA. The aim of this study was to assess the efficacy of EA in removing remnant solid components following the incomplete ablation of benign solid thyroid nodules by RFA. MATERIALS AND METHODS Duri...

This article describes the aetiology, epidemiology and clinical significance of incidental non-solid pulmonary nodules. Non-solid nodules are more likely malignant. If malignant, they are mostly due to atypical adenomatous hyperplasia and bronchioloalveolar carcinoma. As these may be negative on positron emission tomography and slow growing, the diagnostic algorithms that are used for solid nod...

This study evaluated the diagnostic performance of ultrasound elastography (USE) using carotid arterial pulsation and determined the reproducibility of USE for thyroid nodules. A total of 148 patients with 173 thyroid nodules participated. The mean elasticity contrast index (ECI) was significantly higher in malignant nodules (3.1 ± 1.5) than in benign nodules (1.7 ± 0.8) (p < 0.001). When a cut...

Samples of ferromanganese nodules from several localities in Lake Michigan have been analyzed for their minor element content utilizing neutron activation techniques. The thorium and uranium levels in Lake Michigan nodules exhibit marked dissimilarities with marine nodules. The radium content of these freshwater nodules is substantially higher than the reported marine values. The concentrations...

Coexistence between thyroid cancer and hyperthyroidism is rare, most of the nodular lesions from which a malignant tumor documented in this group patients correspond to cold nodules. Justified by increasing number reports literature about tumors diagnosed hot nodules, systematic review was carried out determine possible factors associated with diagnosis nodules hyperthyroidism. The results sugg...

Introduction: In spite of large number of studies regarding relation between thyroid cancer and childhood irradiation, contraversy still exists management of these patients. This study tries to find optimal method of thyroid evaluation in this group. Methods and patients: In a recall program using mass media in Khorasan, all patients with childhood irradiation were invited for thyroid eva...

Using the Solt-Farber hepatocarcinogenesis model, a large population of preneoplastic and neoplastic nodules were induced in male Fischer 344 rats. Total cellular polypeptides from normal liver and individual preneoplastic and neoplastic nodules were analyzed for both qualitative and quantitative changes using computer assisted high resolution two-dimensional electrophoresis. Approximately 800-...

Objective: To explore the diagnostic value of conventional ultrasonography combined with contrast-enhanced in thyroid nodules. Methods: From June 2021 to July 2022, 163 patients nodules enrolled our hospital were selected as research subjects. After pathological diagnosis, 24 cases malignant nodules, and 139 benign The diagnosis rate was observed analyzed, 95% CI. Results: Among them, detection...
