Learning objectives Revise the ACR TI-RADS classification to describe thyroid nodules and ultrasound findings. Review new ultrasound techniques (CEUS, Elastography), which could facilitate the characterization of thyroid nodules. Learn how to prepare a systematic radiological report. Review the indications and correct technique for performing an FNA.
Read more Background Thyroid nodules have a prevalence of up to 20%. In recent years, the incidence of thyroid cancer has increased as a result of the detection of thyroid nodules in imaging tests and the performance of a greater number of biopsies.
Read more Findings and procedure details RADIOLOGICAL REPORT1. Review PREVIOUS STUDIES.2. Description of the THYROID GLAND:•DIMENSIONS of the two thyroid lobes (AP, T, and CC) and AP diameter of the isthmus.•Description of the GLANDULAR PARENCHYMA (echogenicity, vascularization). Normal ECHOGENICITY is homogeneous and greater than neck muscles. In subacute/chronic thyroiditis we can find hypoechoic and poorly defined areas. [fig 1] VASCULARIZATION: can be altered in thyroiditis. [fig 2] 3. Evaluate the LATEROCERVICAL lymph node CHAINS.4. Description of the THYROID NODULES and other pathology Nodules smaller than 5mm should NOT be described. If greater...
Read more Conclusion •Use of classifications (TI-RADS) standardizes the diagnostic criteria in thyroid nodules suspected of malignancy.•Radiological reports must be systematic to facilitate the follow-up of these patients.•Techniques such as Elastography and CEUS seem to be an alternative to reduce the number of FNAs. However, more studies are needed to increase the scientific evidence about these tests.
