Evaluation of an AI-Powered Lung Nodule Algorithm for Detection and 3D Segmentation of Primary Lung Tumors.

, 2019
Automated detection and segmentation is a prerequisite for the deployment of image-based secondary analyses, especially for lung tumors. However, currently only applications for lung nodules ≤3 cm exist.

Hepatic Carcinoma With Epithelial–Myoepithelial Differentiation and Metachronous Intrahepatic Recurrence Following Curative Resection: A Rare Case Report

Hepatology Research, EarlyView.
ABSTRACT Background and Aim Epithelial‐myoepithelial carcinoma (EMC), a malignant tumor with biphasic epithelial and myoepithelial differentiation, is typically a salivary gland neoplasm. Contrastingly, myoepithelial carcinoma (MEC) predominantly comprises myoepithelial cells.

Rapid Intrasegmental Progression After Percutaneous Radiofrequency Ablation for Hepatocellular Carcinoma: Incidence, Imaging Features, and Clinical Outcomes

Hepatology Research, EarlyView.
ABSTRACT Aim Radiofrequency ablation (RFA) is curative therapy for early‐stage hepatocellular carcinoma (HCC), but a rare subset of patients develop aggressive intrasegmental recurrence shortly after complete ablation. We characterized the incidence, risk factors, and absolute risk.

Anthracofibrosis: an under‐recognised mimic of malignancy and tuberculosis in a migrant population

Internal Medicine Journal, EarlyView.
Abstract Anthracosis, usually regarded as a benign and uncommon bronchoscopic finding, was identified in 108 (9.9%) of 1154 bronchoscopy procedures at two Australian hospitals, with almost a third showing bronchial narrowing consistent with anthracofibrosis.

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

CoreFormer high fidelity pulmonary nodule segmentation with structural core priors and geodesic implicit fields

npj Digital Medicine
Accurate delineation of pulmonary nodules in chest computed tomography (CT) is essential for early lung cancer diagnosis and treatment planning. However, voxel-wise segmentation methods often produce fragmented masks and inconsistent topology due to low ...

Intraoperative Contrast-Enhanced Ultrasonography (Io-CEUS) to Detect Missed Lung Nodules During Robot-Assisted Thoracoscopic Surgery. [PDF]

Thorac Cancer
During robotic thoracic surgery, Intraoperative Ultrasound is the surgeon's finger to detect small nodule. ABSTRACT Herein, we reported the use of Intraoperative‐Contrast Enhanced Ultrasonography (Io‐CEUS) during Robotic Assisted Thoracic Surgery (RATS) for identification of malignant lung nodule that was missed during previous operation. Pre‐operative

Unusual Giant Sialocyst Arising From Wharton's Duct: A Case Report

Oral Surgery, EarlyView.
ABSTRACT Background Head and neck masses in adults are a common reason for referral to maxillofacial surgeons and otolaryngologists, and most are benign. True salivary duct cysts (sialocysts) are extremely rare, accounting for < 1% of salivary duct lesions, and primarily involve minor salivary glands. Involvement of major salivary glands is exceptional,

Invasive Fungal Infections in Heart Transplants: A 10‐Year, Single Centre Retrospective Cohort Study From Subtropical Australia

Transplant Infectious Disease, EarlyView.
In this 10‐year retrospective cohort study of heart transplant recipients in subtropical Australia, we characterize the incidence and microbiological profile of invasive fungal infections, highlighting the underappreciated burden of late‐onset and non‐Aspergillus mold infections and the potential underdiagnosis of polymicrobial disease.
