Segmentation of the placenta and its vascular tree in Doppler ultrasound for fetal surgery planning
Enric Perera-Bel,Mario Ceresa,Jordina Torrents-Barrena,Narcís Masoller,Brenda Valenzuela-Alcaraz,Eduard Gratacós,Elisenda Eixarch,Miguel Ángel González Ballester +7 more
TL;DR: A semiautomatic algorithm to detect the placenta, both umbilical cord insertions and the placental vasculature from Doppler ultrasound and provides a near real-time user experience and requires short training without compromising the segmentation accuracy.
Journal ArticleDOI
A new approach using image analysis to assess pulmonary hypoplasia in the fetal lamb diaphragmatic hernia model
Takuya Kawaguchi,Kohei Kawaguchi,Juma Obayashi,Kunihide Tanaka,Kei Ohyama,Yasuji Seki,Hideki Nagae,Shigeyuki Furuta,Kevin C. Pringle,Hiroaki Kitagawa +9 more
TL;DR: In this paper, the authors evaluated bronchial area (BA) by bronchography in a fetal lamb DH model to develop a measure of pulmonary hypoplasia (PH) and also pulmonary vascular and bronchia abnormalities.
Journal ArticleDOI
An Accurate Segmentation Framework for Static Ultrasound Images of the Gestational Sac
TL;DR: An accurate segmentation framework for gestational sac ultrasound images from two different scanning machines is proposed based on an improved level-set algorithm driven by shape domain-specific knowledge and shows better performance than other commonly used segmentation methods.
Journal ArticleDOI
Contour Dice loss for structures with Fuzzy and Complex Boundaries in Fetal MRI
Bella Specktor Fadida,Bossmat Yehuda,Daphna Sourani,Liat Ben Sira,Dafna Ben Bashat,Leo Joskowicz +5 more
TL;DR: A new formulation of the loss akin to the Contour Dice metric is described, which is computed efficiently for each slice via erosion, dilation and XOR operators and yielded the best performance for placenta segmentation.
Journal ArticleDOI
Fuzzy based region growing segmentation with modified least square fitting algorithm for automatic fetal growth estimation
TL;DR: In this paper , a Discrete Wavelet Transform (DWT) based fuzzy region growing segmentation scheme was proposed for automatic estimation of gestation age using the head circumference data obtained/ retrieved from the ultrasonic images of the fetus.

Efficient Multi-Scale 3D CNN with Fully Connected CRF for Accurate Brain Lesion Segmentation
Konstantinos Kamnitsas,Christian Ledig,Virginia F. J. Newcombe,Joanna P. Simpson,Andrew D. Kane,David K. Menon,Daniel Rueckert,Ben Glocker +7 more
TL;DR: An efficient and effective dense training scheme which joins the processing of adjacent image patches into one pass through the network while automatically adapting to the inherent class imbalance present in the data, and improves on the state-of-the‐art for all three applications.
Journal ArticleDOI
A Randomized Trial of Prenatal versus Postnatal Repair of Myelomeningocele
N. Scott Adzick,Elizabeth Thom,Catherine Y. Spong,John W. Brock,Pamela K. Burrows,Mark P. Johnson,Lori J. Howell,Jody A. Farrell,Mary E. Dabrowiak,Leslie N. Sutton,Nalin Gupta,Noel Tulipan,Diana L. Farmer +12 more
TL;DR: Prenatal surgery for myelomeningocele reduced the need for shunting and improved motor outcomes at 30 months but was associated with maternal and fetal risks and increased risk of preterm delivery and uterine dehiscence at delivery.

Interactive Medical Image Segmentation Using Deep Learning With Image-Specific Fine Tuning
Guotai Wang,Wenqi Li,Maria A. Zuluaga,Rosalind Pratt,Premal A. Patel,Michael Aertsen,Tom Doel,Anna L. David,Jan Deprest,Sebastien Ourselin,Tom Vercauteren +10 more
TL;DR: A novel deep learning-based interactive segmentation framework by incorporating CNNs into a bounding box and scribble-based segmentation pipeline and proposing a weighted loss function considering network and interaction-based uncertainty for the fine tuning is proposed.
Journal ArticleDOI
The ultrasonic changes in the maturing placenta and their relation to fetal pulmonic maturity.
TL;DR: A correlation between maturational changes of the placenta as seen by ultrasound and fetal pulmonic maturity as indicated by L/S ratio is suggested.
