Validación ecográfica-tirads en pacientes con patología tiroidea. Hospital Vicente Corral Moscoso y Hospital José Carrasco Arteaga. Cuenca, 2012.

Abstract

Introduction: The thyroid gland is a hormone-producing organ that plays an important role in metabolism. The classification TIRADS (Thyroid Imaging Reporting and Data System) gathers ultrasound scan patterns to differentiate between benign and malignant nodules in a better way, this means a better selection of patients who need surgery and cytology studies. Objectives: To validate the ultrasound classification- TIRADS in patients with thyroid disease who undergo ultrasound for evaluation of thyroid gland in Cuenca, Ecuador. Materials and methods: This validation study of diagnostic test, analyzed the thyroid pathology through ultrasound scan in relation to cytology as a gold standard with thin needle aspiration puncture technique. Results: We studied 860 patients, 710 women and 150 men. Validation values in this study were: sensitivity 97,87%, specificity 72,32%, 30,26% positive predictive value, negative predictive value 99,64%, Youden test 0.70, positive likelihood ratio of 3.54 and negative likelihood ratio of 0.03. Conclusions: TIRADS classification is a highly sensitive method that can be used in imaging services in the studied hospitals.
