FetalDenseNet: multi-scale deep learning for enhanced early detection of fetal anatomical planes in prenatal ultrasound

Key Points

DenseNet169 showed the highest classification accuracy of 92% for fetal anatomical planes.
The study evaluated five CNN architectures on a dataset of 12,400 ultrasound images from 1,792 patients.
Preprocessing techniques like scaling and normalization were applied to enhance model performance.
Improvements in diagnostic accuracy benefit clinical decision-making for prenatal care.

Abstract

Abstract Objectives The study aims to improve the classification of fetal anatomical planes using Deep Learning (DL) methods to enhance the accuracy of fetal ultrasound interpretation. Methods Five Convolutional Neural Network (CNN) architectures, such as VGG16, ResNet50, InceptionV3, DenseNet169, and MobileNetV2, are evaluated on a large-scale, clinically validated dataset of 12,400 ultrasound images from 1,792 patients. Preprocessing methods, including scaling, normalization, label encoding, and augmentation, are applied to the dataset, and the dataset is split into 80 % for training and 20 % for testing. Each model was fine-tuned and evaluated based on its classification accuracy for comparison. Results DenseNet169 achieved the highest classification accuracy of 92 % among all the tested models. Conclusions The study shows that CNN-based models, particularly DenseNet169, significantly improve diagnostic accuracy in fetal ultrasound interpretation. This advancement reduces error rates and provides support for clinical decision-making in prenatal care.
