Abstract

        Objective: To determine the useful of ACR TI-RADS classification in predicting thyroid malignancy at Prachuapkhirikhan Hospital.

        Material and Methods: The radiological reports of patients which diagnosed as ACR TI-RADS classification and pathological records at Prachuapkhirikhan Hospital from January 1, 2018 to July 31, 2018 were retrospectively studied. The risk of malignancy of each ACR TI-RADS category was determined. Statistical accesses of some major ultrasound features were analyzed.

        Results: Total of 137 patients who underwent ultrasound of thyroid glands at Prachuapkhirikhan Hospital, 55 patients were included. Seven out of 55 (12.7%) patients were thyroid cancer. The risk of malignancy in ACR TI-RADS 3, 4 and 5 categories were about 5.6%, 11.1% and 57.1%, respectively. Specificity of taller-than-wide shape, extra-thyroidal extension, irregular or lobulated margins, very hypoechogenicity and microcalcification in ultrasound features for thyroid malignancy were 100%, 100%, 87.5%, 77.1% and 68.8%, respectively.

        Conclusion: For predicting thyroid malignancy. Fine-needle biopsy is most often done in a suspected malignant nodule and ACR TI-RADS classification is useful.
