The role of microflow patterns combined with greyscale ultrasound in enhancing diagnostic validity and reducing unnecessary biopsy rate of thyroid nodules

1

Thyroid cancer is increasingly prevalent, necessitating accurate preoperative diagnosis to guide treatment decisions.
2

Current ultrasound risk stratification systems for thyroid nodules often yield low specificity for biopsy recommendations.
3

Superb microvascular imaging (SMI) enhances the visualization of microflow patterns in thyroid nodules, aiding in differentiation between benign and malignant cases.
4

The study aims to assess the combined diagnostic validity of SMI and greyscale ultrasound in reducing unnecessary biopsies for thyroid nodules.
5

Microflow patterns identified through SMI may improve the accuracy of thyroid nodule assessments compared to traditional greyscale ultrasound alone.
