Abstract

Automatic computerized segmentation of fetal head from ultrasound images and head circumference (HC) biometric measurement is still challenging, due to the inherent characteristics of fetal ultrasound images at different semesters of pregnancy. In this paper, we proposed a new deep learning method for automatic fetal ultrasound image segmentation and HC biometry: deeply supervised attention-gated (DAG) V-Net, which incorporated the attention mechanism and deep supervision strategy into V-Net models. In addition, multi-scale loss function was introduced for deep supervision. The training set of the HC18 Challenge was expanded with data augmentation to train the DAG V-Net deep learning models. The trained models were used to automatically segment fetal head from two-dimensional ultrasound images, followed by morphological processing, edge detection, and ellipse fitting. The fitted ellipses were then used for HC biometric measurement. The proposed DAG V-Net method was evaluated on the testing set of HC18 (n = 355), in terms of four performance indices: Dice similarity coefficient (DSC), Hausdorff distance (HD), HC difference (DF), and HC absolute difference (ADF). Experimental results showed that DAG V-Net had a DSC of 97.93%, a DF of 0.09 ± 2.45 mm, an AD of 1.77 ± 1.69 mm, and an HD of 1.29 ± 0.79 mm. The proposed DAG V-Net method ranks fifth among the participants in the HC18 Challenge. By incorporating the attention mechanism and deep supervision, the proposed method yielded better segmentation performance than conventional U-Net and V-Net methods. Compared with published state-of-the-art methods, the proposed DAG V-Net had better or comparable segmentation performance. The proposed DAG V-Net may be used as a new method for fetal ultrasound image segmentation and HC biometry. The code of DAG V-Net will be made available publicly on https://github.com/xiaojinmao-code/ .

  • Five studies used the freely available 'HC18' data set for training and testing algorithms, which contained 1334 2D images from 551 women of the standard fetal head plane.

    “Five studies used the freely available ‘HC18’ data set [45] for training and testing the algorithms, which contained 1334 2D images from 551 women of the standard fetal head plane [18,34,37,38,40].”

    The Dataset section confirms that this study used the open-access HC18 dataset for training and testing and that its images came from 551 pregnant women. It reports 1,354 two-dimensional images, however, not the claimed 1,334. As one of five cited studies, this paper establishes its own use of HC18, not the other studies’ use. (LLM, conf=0.89)

    The Discussion (page unavailable) describes point-of-care use as a potential application and reports a 6.3 ms execution time on a computer. The Introduction (page unavailable) says the attention modules add few parameters at low computational cost. The paper does not report applying the algorithm on point-of-care devices or using it to acquire standard planes; it studies head segmentation and circumference measurement from existing images.

    The Discussion (page not provided) identifies point-of-care use and medically underserved areas as potential applications of automated fetal head-circumference measurement. It does not say the model improves ultrasound image acquisition or diagnostic accuracy in point-of-care devices; the dataset described in the Experiments section used images acquired by experienced sonographers.

  • AI models designed for automatic biometric measurements are usually restricted to a specific range of GA and can fail in images of different GA.

    The Results and Discussion report that the model performed less well in the first trimester and had larger head-circumference errors in the third, supporting sensitivity to gestational stage. They do not say that AI models are usually restricted to a specific GA range or fail on images outside it; this model was tested across all three trimesters. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
