The classification system of the thyroid nodules (TN) TI-RADS (Thyroid Imaging Reporting and Data System)is rarely used. The aim of this work is to make this classification easierthrough a practical guide.
The widespread use of ultrasonography (US) has contributed to theincreased detection of thyroid nodules. Thyroid US depicts nodules in up to 67% of the population.
However,Less than 10% of these nodules are malignant . Although many reports have demonstrated malignant US features thatnecessitate US-guided fine needle aspiration biopsy (FNAB) ,
it was hard to decide which lesions should undergo FNAB because the same thyroidnodule may be classified in different ways with different guidelines ....
Findings and procedure details
Horvath et al have suggested a reporting data system forthyroid lesions in stratifying the malignant risk of nodules . The author used the categorization system of US features in thyroidnodules and demonstrated the risk of malignancy in each category. This classification system is based on the Breast Imaging Reporting andData System (BI-RADS),
which was developed by the American Collegeof Radiology . The BI-RADS has been designed to help standardize breast imagingreports,
TI-RADS score was first established by Horvath.
Many others proposeda practical approach to make its application easier. All studies about TIRADS reliability had not been void of limitations,which include retrolective data collection and the fact that histology wasnot available for all of the thyroid nodules,
as those with a benigncytology were not operated for ethical reasons. TIRADS gives us the ability to detect most thyroid carcinomas and to assert benign status with good reliability....
