EXTERNAL VALIDATION OF AIBX V2 ALGORITHM FOR THYROID NODULE RISK STRATIFICATION

External validation of AIBx version 2 was presented at the Amercian Thyroid Association's annual meeting (2022) at Montreal by Dr. Singh et.al.

AIBx V2 had a negative predictive value of 98.5%, which was similar to fine needle aspiration biopsies. Sensitivity and specificity for the model were 92% and 86% respectively. Full abstract can be viewed at Late Breaking Abstracts | Thyroid (liebertpub.com)

Combining Image Similarity and Predictive AI Models to Decrease Subjectivity in Thyroid Nodule Diagnosis and Improve Malignancy Prediction

Research by Nair et.al. presented at SIIM CMIMI 2022.

AIBx V2 was able to predict the histopathologically proven presence of malignancy accurately. None of the thyroid cancers were missed by the algorithm. The AI algorithm was able to reduce unnecessary biopsy in 50.5% of the nodules.

Abstract

Background: Current classification systems for thyroid nodules are very subjective. Artificial intelligence (AI) algorithms have been used to decrease subjectivity in medical image interpretation. One out of 2 women over the age of 50 years may have a thyroid nodule and at present the only way to exclude malignancy is through invasive procedures for those that are suspicious on ultrasonography. Hence, there exists a need for noninvasive objective classification of thyroid nodules. Some cancers have benign appearance on ultrasonogram. Hence, we decided to create an image similarity algorithm rather than image classification algorithm.
