Resumen
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.
