A Convolutional Approach to Vertebrae Detection and Labelling in Whole Spine MRI [PDF]

arXiv, 2020
We propose a novel convolutional method for the detection and identification of vertebrae in whole spine MRIs. This involves using a learnt vector field to group detected vertebrae corners together into individual vertebral bodies and convolutional image-to-image translation followed by beam search to label vertebral levels in a self-consistent manner.

Robust vertebra identification using simultaneous node and edge predicting Graph Neural Networks [PDF]

arXiv, 2023
Automatic vertebra localization and identification in CT scans is important for numerous clinical applications. Much progress has been made on this topic, but it mostly targets positional localization of vertebrae, ignoring their orientation. Additionally, most methods employ heuristics in their pipeline that can be sensitive in real clinical images ...

Prognostic Impact of Bone Mineral Density Reduction During Neoadjuvant Chemotherapy (NAC) in Patients Undergoing NAC Followed by Esophagectomy for Esophageal Cancer

Annals of Gastroenterological Surgery, EarlyView.
The association between BMD reduction during NAC and the worse prognosis remains unknown, although NAC followed by esophagectomy is a standard treatment for advanced ESCC. This study appeared that BMD massive reduction was an independent prognostic factor on OS (HR, 3.30; 95% confidence interval [CI], 1.69–6.55) and RFS (HR, 2.08; 95% CI, 1.19–3.63 ...

Region-specific Dictionary Learning-based Low-dose Thoracic CT Reconstruction [PDF]

arXiv, 2020
This paper presents a dictionary learning-based method with region-specific image patches to maximize the utility of the powerful sparse data processing technique for CT image reconstruction. Considering heterogeneous distributions of image features and noise in CT, region-specific customization of dictionaries is utilized in iterative reconstruction ...

Relationship Between Kyphosis and Postoperative Gastroesophageal Reflux After Proximal Gastrectomy

Annals of Gastroenterological Surgery, EarlyView.
This study examined the relationship between kyphosis and postoperative gastroesophageal reflux disease (GERD) after proximal gastrectomy using a kyphosis definition that is familiar to surgeons for preoperative assessment. Multivariate analysis revealed that kyphosis is an independent risk factor for GERD after proximal gastrectomy.

Temporal and phylogenetic evolution of the sauropod dinosaur body plan [PDF]

, 2016
The colossal size and body plan of sauropod dinosaurs are unparalleled in terrestrial vertebrates. However, to date, there have been only limited attempts to examine temporal and phylogenetic patterns in the sauropod bauplan.

Hereditary Multiple Osteochondromas and Acute Lymphoblastic Leukemia: A Possible Role for EXT1 and EXT2 in Hematopoietic Malignancies

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Hereditary multiple osteochondromas (HMO) is an autosomal dominant disorder caused by heterozygous deleterious variants in the EXT1 or EXT2 genes. While the clinical core phenotype is well established and mainly consists of bone deformities, limb length discrepancies, multiple benign bone neoplasms, and increased risk of chondrosarcoma, the ...

Compound Heterozygous Variants in ZSWIM7 Gene Linked to Infertility and Its Role in Gonadal Development

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This study aims to elucidate the role of the ZSWIM7 gene in the etiology of infertility, focusing on its potential association with premature ovarian insufficiency and azoospermia. We investigated an 18‐year‐old female patient who presented with primary amenorrhea, hypoplasia of the uterus and ovaries, Tanner stage II breast and pubic hair ...

Retrospective analysis of deformed complex vertebral osteotomy in children with severe thoracic post-tubercular angular kyphosis

BMC Musculoskeletal Disorders, 2022
Background Many surgical options have been described to manage post-tubercular kyphosis, but the standard approach for treating severe post-tubercular angular kyphosis in children has not been established yet.

Spinal Dural Arteriovenous Fistula in a Pediatric Patient with History of Endovascular Therapy Failure: A Case Report

Surabaya Physical Medicine and Rehabilitation Journal, 2023
Spinal Dural Arteriovenous Fistula (SDAVF) cases in children are extremely rare and pose a high risk for intraoperative hemorrhage. The clinical manifestation and imaging results may be vague and deceptive, frequently mistaken for other conditions such ...
