Thyroid Ultrasound Using ACR TI-RADS™

This educational activity allows the learner to further develop their interpretation proficiency of thyroid nodules by using ACR TI-RADS to reduce unnecessary biopsies.

This activity is divided into a pre-test comprised of seven cases, followed by 18 learning cases (with case feedback), and a post-test of seven cases.

The learner will assess each case for sonographic features including composition, echogenicity, margins, shape, and echogenic foci, to determine the risk category.

  2. Describe the difference between thyroid nodule signs under categories of composition, echogenicity, margins, shape and echogenic foci. 
  3. Identify nodules that do not need further biopsy or follow-up ultrasound.
