Unsupervised Anomaly Detection of Paranasal Anomalies in the Maxillary Sinus [PDF]

arXiv, 2022
Deep learning (DL) algorithms can be used to automate paranasal anomaly detection from Magnetic Resonance Imaging (MRI). However, previous works relied on supervised learning techniques to distinguish between normal and abnormal samples. This method limits the type of anomalies that can be classified as the anomalies need to be present in the training ...

Granulomatosis with polyangiitis: Common and uncommon presentations

Journal of Medical Imaging and Radiation Oncology, Volume 66, Issue 8, Page 1089-1096, December 2022., 2022
Summary Granulomatosis with polyangiitis (GPA) is a multisystemic autoimmune small vessel vasculitis predominantly affecting the respiratory and renal systems. Other systems such as the central nervous system, orbital, cardiac and gastrointestinal systems may also be involved to a lesser degree.

Proton beam therapy in paediatric cancer: Anticipating the opening of the Australian Bragg Centre for Proton Therapy and Research

Journal of Medical Imaging and Radiation Oncology, EarlyView., 2023
Summary Proton Beam Therapy (PBT) has the potential to improve paediatric cancer care by reducing radiation exposure and thus long‐term toxicities. Ethical concerns and debates surrounding the treatment, such as eligibility and accessibility, are ongoing in Australia. The Australian Bragg Centre for Proton Therapy and Research (ABCPTR) (named after Sir

Multiple Instance Ensembling For Paranasal Anomaly Classification In The Maxillary Sinus [PDF]

arXiv, 2023
Paranasal anomalies are commonly discovered during routine radiological screenings and can present with a wide range of morphological features. This diversity can make it difficult for convolutional neural networks (CNNs) to accurately classify these anomalies, especially when working with limited datasets. Additionally, current approaches to paranasal

Ossifying fibromas of the paranasal sinuses: diagnosis and management

Acta otorhinolaryngologica italica, 2015
SUMMARY Fibro-osseous benign lesions rarely affect the sinonasal tract and are divided into 3 different entities, namely osteoma, fibrous dysplasia and ossifying fibroma.

Red blood cell endothelial nitric oxide synthase: A major player in regulating cardiovascular health

British Journal of Pharmacology, EarlyView., 2023
Abstract Red blood cells (RBCs) have traditionally been seen as simple carriers of gases and nutrients in the body. One important non‐canonical function of RBCs in the cardiovascular system is the regulation of nitric oxide (NO) metabolism. It has been shown that RBCs can scavenge NO, transport NO metabolites and produce NO in hypoxic conditions ...

A patient presenting with concha bullosa in another concha bullosa: a case report

Journal of Medical Case Reports, 2012
Introduction Anatomic variations of the paranasal sinuses are very common. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of
