Aims and objectives
The widespread use of ultrasonography has contributed to increased detection of thyroid nodules.
Nodular thyroid disease was classified by different guidelines and it was difficult to determine which nodule was suspicious of malignancy.
TIRADS (Thyroid Imaging Reporting And Data System) is a reporting data system for thyroid lesions,
proposed to standardize the reporting of results of thyroid ultrasound that can be understood by clinicians and also to stratify the risk of malignancy of a lesion based on ultrasound features.
Itwas introduced by Horvath et alin...
Methods and materials
STUDY DESIGN:Cross sectional study- diagnostic test evaluation
STUDY PERIOD:From December 2015- November 2017
STUDY POPULATION:104 patients with focal thyroid nodules on ultrasonography in the Department of Radiodiagnosis at Dr.
Somervell Memorial CSI Medical College,
Karakonam during the study period.
PROCEDURE:Ultrasound scan of thyroid gland was performed with 5-12 MHz linear-array transducer of Voluson pro 730 machine using an optimized gain.
A nodule was classified according to Russ modified TIRADS.If multiple nodules are present,
the characteristics of the most suspicious nodule was taken into account.
If...
Results
Out of the total 104 patients studied,
93.3% were benign and 6.7% were malignant.
Benign cases were colloid nodules (55 cases),
lymphocytic thyroiditis (8 cases),
benign follicular adenoma (33 cases) and Hurthle cell adenoma (1 case).
The most common benign nodule was colloid nodule.
Malignant cases were Papillary carcinoma (2 cases),
Follicular carcinoma (3 cases),
Medullary and Hurthle cell carcinoma (1 case each).
The most common malignancy in our study was Follicular carcinoma,
followed by Papillary carcinoma.
TIRADS 2 Features
In our study,19 nodules had...
Conclusion
CONCLUSION
When TIRADS 2 & 3 are considered benign and TIRADS 4A,
4B & 5 are considered malignant,
TIRADS score had high negative predictive value (98.5%).
Therefore,
if a nodule was assigned a benign score of TIRADS 2/3,
it is highly unlikely to be malignant,
thus helping to avoid unnecessary FNAs and / or surgical excision.
All nodules assigned as TIRADS 2 (benign) turned out to be benign.
As the TIRADS score increases,
the risk of malignancy increases.
As echogenicity decreases,
risk of malignancy increases....
