A new radiomics nomogram accurately characterizes thyroid nodules, improving diagnostic performance and reducing unnecessary fine needle aspiration biopsy (FNA) rates. This noninvasive method offers a cost-effective approach for thyroid nodule evaluation.
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Thyroid nodules are common, requiring accurate characterization to differentiate benign from malignant lesions.
- Current diagnostic methods, such as the American College of Radiology Thyroid Imaging, Reporting and Data System (ACR TI-RADS), have limitations in diagnostic performance.
- Reducing unnecessary fine needle aspiration biopsy (FNA) is crucial for patient management and healthcare costs.
Purpose of the Study:
- To develop and validate a radiomics model for enhanced diagnostic performance in thyroid nodules.
- To reduce the rate of unnecessary fine needle aspiration biopsy (FNA).
- To improve the clinical net benefit of thyroid nodule characterization.
Main Methods:
- A retrospective study of 217 thyroid nodules was conducted, with lesions divided into training and verification cohorts.
- Radiomics scores were derived from B-mode ultrasound (B-US) and strain elastography (SE) images.
- A radiomics nomogram was constructed by combining ultrasonic features and the best-performing radiomics score, and its performance was compared to ACR TI-RADS and a combined advanced clinical score.
Main Results:
- The radiomics nomogram achieved an area under the receiver operating characteristic curve (AUC) of 0.909, significantly higher than the ACR TI-RADS score.
- The nomogram demonstrated an equivalent diagnostic performance to the combined TI-RADS+SE+CEUS score.
- The unnecessary FNA rate was significantly lower with the radiomics nomogram compared to ACR TI-RADS, with comparable rates to the advanced clinical score.
Conclusions:
- The developed radiomics nomogram serves as an objective, accurate, and noninvasive tool for thyroid nodule characterization.
- This approach enhances diagnostic accuracy and reduces unnecessary invasive procedures.
- The radiomics nomogram offers a cost-effective method for improving clinical decision-making in thyroid nodule management.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
