Quantifying spatial and dynamic lung abnormalities with 3D PREFUL FLORET UTE imaging: A feasibility study

open access: yesMagnetic Resonance in Medicine, Volume 93, Issue 5, Page 1984-1998, May 2025.
Abstract Purpose Pulmonary MRI faces challenges due to low proton density, rapid transverse magnetization decay, and cardiac and respiratory motion. The fermat‐looped orthogonally encoded trajectories (FLORET) sequence addresses these issues with high sampling efficiency, strong signal, and motion robustness, but has not yet been applied to phase ...

Fever duration enhanced biomarker sensitivity in diagnosing radiographically confirmed community‐acquired pneumonia in children

open access: yesActa Paediatrica, Volume 114, Issue 5, Page 1015-1021, May 2025.
Abstract Aim Our aim was to examine how fever duration affected the ability of biomarkers to diagnose community‐acquired pneumonia (CAP). Methods This was a retrospective cohort study of children aged 2–18 years who attended the emergency department at Schneider Children's Medical Centre of Israel with CAP from June 2015 to May 2020.

Fuzzy Attention-based Border Rendering Network for Lung Organ Segmentation [PDF]

open access: yesarXiv
Automatic lung organ segmentation on CT images is crucial for lung disease diagnosis. However, the unlimited voxel values and class imbalance of lung organs can lead to false-negative/positive and leakage issues in advanced methods. Additionally, some slender lung organs are easily lost during the recycled down/up-sample procedure, e.g., bronchioles ...

Prevalence of Smoking Among Spontaneous Pneumothorax Patients and Its Impact on Treatment in Syria Country: A Cross‐Sectional Study

open access: yesHealth Science Reports, Volume 8, Issue 4, April 2025.
ABSTRACT Background and Aims Spontaneous Pneumothorax (SP) is a case where air is collected in the pleural space, with smoking recognized as a major risk factor. Despite the global burden of SP, there is limited research on its prevalence and recurrence in Middle Eastern populations, particularly in Syria.

Lung-DETR: Deformable Detection Transformer for Sparse Lung Nodule Anomaly Detection [PDF]

open access: yesarXiv
Accurate lung nodule detection for computed tomography (CT) scan imagery is challenging in real-world settings due to the sparse occurrence of nodules and similarity to other anatomical structures. In a typical positive case, nodules may appear in as few as 3% of CT slices, complicating detection.

Quantifying Spatial Distribution of Ventilation Defects in Multiple Pulmonary Diseases With Hyperpolarized 129Xenon MRI

open access: yesJournal of Magnetic Resonance Imaging, Volume 61, Issue 4, Page 1860-1873, April 2025.
Background Hyperpolarized 129Xe MRI assesses lung ventilation, often using the ventilation defect percentage (VDP). Unlike VDP, defect distribution index (DDI) quantifies spatial clustering of defects. Purpose To quantify spatial distribution of 129Xe ventilation defects using DDI across pulmonary diseases. Study Type Retrospective.
