The value of ultrasound in the diagnosis of thyroid cancer
Main Article Content
Abstract
Objective: To determine the value of ultrasound in the diagnosis of thyroid cancer.
Subjects and methods: A cross-sectional descriptive study on 98 patients with thyroid nodules who came for treatment at the Military Institute of Medical Radiology and Oncology, from April 2020 to March 2021.
Results: The size of malignant nodules was mainly less than 2cm. Thyroid cancer lesions were mainly characterized by highly hypoechoic on ultrasound (61.19%). Thyroid cancer nodules had taller-than-wide feature (Sensitivity: 76.12%; specificity: 86.96%; positive predictive value: 89.47%; negative predictive value: 71.43%; accuracy: 80.53%.); irregular border feature (sensitivity: 98.51%; specificity: 86.96%; positive predictive value: 91.67%; negative predictive value: 97.56%; accuracy: 93.81%); microcalcification characteristics (sensitivity: 73.13%; specificity: 91.30%; positive predictive value: 92.45%; negative predictive value: 70.00%; accuracy: 80,53%). TIRADS value in thyroid cancer diagnosis with sensitivity: 94.03%; specificity: 86.96%; positive predictive value: 91.30%; negative predictive value: 90.91%; Accuracy: 91.15%.
Conclusion: The features of hypoechoic nodules, taller-than-wide shape, irregular border, microcalcification characteristics, and TIRADS 4, TIRADS 5 scores had high prognostic value for thyroid cancer.
