Elastografía por ondas de corte como herramienta en la evaluación de los nódulos tiroideos

Gac. méd. Méx; 157 (1), 2021
Resumen Introducción: La elastografía por ondas de corte (SWE) ha demostrado ser predictiva de malignidad en nódulos tiroideos. Objetivo: Determinar mediante SWE, el punto de corte de la rigidez con mayor especificidad y sensibilidad para detectar nódulos tiroideos que requieren cirugía. Métodos...

Is there a place for measuring serum calcitonin prior to thyroidectomy in patients with a non-diagnostic thyroid nodule biopsy?

ABSTRACT Objective: To verify the cytopathological Bethesda System classification of thyroid nodule fine-needle aspiration biopsy (FNAB) in MTC patients and to assess the role of preoperative serum calcitonin (CT) levels in the investigation of this neoplasm in medullary thyroid cancer (MTC) patients un...

Microcalcificaciones en ausencia de nódulo tiroideo identificable por ecografía y su asociación a cáncer de tiroides: a propósito de un caso

La ecografía tiroidea es la principal herramienta diagnóstica en el manejo de los nódulos tiroideos, siendo la presencia de microcalcificaciones un signo de malignidad. Sin embargo, existen escasas publicaciones acerca de la presencia de microcalcificaciones en ausencia de nódulo identificable y su a...

Are the anatomical, clinical, and ultrasound characteristics of thyroid nodules with Bethesda III or IV cytology and ACR TI-RADS 3, 4, or 5 able to refine the indications for molecular diagnostic tests?

ABSTRACT Objective: To analyze the association of clinical, anatomical, and ultrasound (US) characteristics of malignancies in Bethesda III or IV (III-B or IV-B) thyroid nodules. Subjects and methods: The association between malignancies and the following variables were analyzed: III-B or IV-B, age <...

Comparative Study of the Level of Inflammatory Factors of Erythrocyte Sedimentation Rate and Reactive Protein C in Benign and Malignant Thyroid Nodules

ABSTRACT Objective: To evaluate the level of inflammatory factors of erythrocyte sedimentation rate and reactive protein C in benign and malignant thyroid nodules. Material and Methods: In this case-control study, patients who were referred because of an enlarged thyroid gland were selected, patients w...

Comparison of different ultrasound classification systems of thyroid nodules for identifying malignant potential: a cross-sectional study

Clinics; 76 (), 2021
OBJECTIVE: In our organization, it has been necessary in our organization to calculate the risk categories according to the American Thyroid Association (ATA), the American Association of Clinical Endocrinologists/American College of Endocrinology/Associazione Medici Endocrinologi (AACE/ACE/AME), and the...

Role of elastography strain ratio and TIRADS score in predicting malignant thyroid nodule

ABSTRACT Objective: Ultrasonography (US) is the most accurate and cost-effective imaging method in diagnosis of thyroid nodules. A practical thyroid imaging reporting and data system (TIRADS) for thyroid nodules has been proposed to classify nodules of the thyroid gland to solve the problem of nodule se...

Determination of the functional characteristics of thyroid nodules through nuclear medicine images in patients, who attended the Instituto de Investigaciones en Ciencias de la Salud - UNA, in the period 2016-2019

nuclear permiten visualizar la estructura y función de un órgano, tejido, hueso o sistema dentro del cuerpo, entre ellos la glándula tiroidea, la cual puede presentar un nódulo tiroideo y este es importante diagnosticar por su potencial malignidad. Objetivo: Determinar las características funcional...

Use of strain ultrasound elastography versus fine-needle aspiration cytology for the differential diagnosis of thyroid nodules: a retrospective analysis

Clinics; 75 (), 2020
OBJECTIVE: Fine-needle aspiration cytology is the risk stratification tool for thyroid nodules, and ultrasound elastography is not routinely used for the differential diagnosis of thyroid cancer. The current study aimed to compare the diagnostic parameters of ultrasound elastography and fine-needle aspir...
