Development of Artificial Intelligence Image Classification Models for Determination of Umbilical Cord Vascular Anomalies

Abstract

ObjectiveThe goal of this work was to develop robust techniques for the processing and identification of SUA using artificial intelligence (AI) image classification models.MethodsUltrasound images obtained retrospectively were analyzed for blinding, text removal, AI training, and image prediction. After developing and testing text removal methods, a small n‐size study (40 images) using fastai/PyTorch to classify umbilical cord images. This data set was expanded to 286 lateral‐CFI images that were used to compare: different neural network performance, diagnostic value, and model predictions.ResultsAI‐Optical Character Recognition method was superior in its ability to remove text from images. The small n‐size mixed single umbilical artery determination data set was tested with a pretrained ResNet34 neural network and obtained and error rate average of 0.083 (n = 3). The expanded data set was then tested with several AI models. The majority of the tested networks were able to obtain an average error rate of <0.15 with minimal modifications. The ResNet34‐default performed the best with: an image‐classification error rate of 0.0175, sensitivity of 1.00, specificity of 0.97, and ability to correctly infer classification.ConclusionThis work provides a robust framework for ultrasound image AI classifications. AI could successfully classify umbilical cord types of ultrasound image study with excellent diagnostic value. Together this study provides a reproducible framework to develop AI‐specific ultrasound classification of umbilical cord or other diagnoses to be used in conjunction with physicians for optimal patient care.
