Ultrasonographic correlation between thyroid volume and ti-rads. Prospective study

Abstract

The scientific community has been concerned with quantifying thyroid volume according to variables such as sex, age, and associated iodine deficiencies; however, despite the global use of TI-RADS to estimate the risk of malignancy in thyroid pathologies, there is not enough information in regarding whether or not the size of the gland is related to this scale. OBJECTIVE: to compare the Thyroid Volume with TI-RADS in patients treated in the diagnostic ultrasound unit of the Naguanagua Clinical Center in the period January 2022 - January 2023. METHODS: observational-descriptive study of a comparative level, with a cross-sectional and prospective design. Non-probabilistic census sample, covering all the patients who underwent thyroid ultrasound in the established period. A record was made regarding the quantification of the volume of: right thyroid lobe, left thyroid lobe and total thyroid, TI-RADS, age and sex of the patient. The ANOVA statistic was used and the free license Statistical® program was used. RESULTS: sample of 126 patients, mean age 51.71 ± 1.44 years, median 53 years. When the Total Thyroid Volume was compared with TI-RADS, it was found that the highest mean was registered by those patients classified as 4B (p <0.05). CONCLUSION: even when higher total glandular volume averages are recorded in patients with nodular findings, it is noteworthy that among the recorded data there are patients with values very similar to those reported in the literature as normal volumes in the presence of thyroid nodular pathology.
