Elastosonography improves thyroid nodule characterization, identifying hard nodules (classes III-IV) as high-risk for malignancy. This technique aids in selecting patients needing tissue diagnosis or close follow-up.

Area of Science:

  • Endocrinology
  • Medical Imaging
  • Oncology

Background:

  • Conventional ultrasound (US) is standard for thyroid lesion diagnosis.
  • Characterization of thyroid nodules with US alone is often limited.
  • Tissue diagnosis is frequently required for definitive management.

Purpose of the Study:

  • To evaluate the utility of elastosonography as an adjunct to conventional US.
  • To improve the characterization of thyroid nodules.
  • To better direct patient management based on lesion properties.

Main Methods:

  • 96 patients with solid thyroid nodules underwent conventional US and elastosonography.
  • Elastosonography classified nodules as soft (classes I-II) or hard (classes III-IV).
  • Results were correlated with fine needle aspiration (FNA) histology.

Main Results:

  • 95 nodules were soft (classes I-II), and 13 were hard (classes III-IV).
  • No cancers were found in soft nodules; 6 cancers were detected in hard nodules.
  • FNA yielded insufficient material in 7 nodules (5 soft, 2 hard).

Conclusions:

  • Real-time elastosonography enhances conventional US for thyroid nodule evaluation.
  • It helps identify patients at high risk for malignancy.
  • This can guide decisions for tissue diagnosis or follow-up.
