Comparison of stationary digital chest tomosynthesis to portable chest radiographs: A patient study. [PDF]

PLoS ONE
BackgroundPortable chest radiographs are a vital tool for clinical evaluation. However, their value remains limited due to overlapping anatomical structures obscuring underlying pathologies.

Vacuum-Assisted Breast Biopsy and Post-Biopsy Scarring: Implications for Imaging Interpretation [PDF]

Diagnostics
Background/Objectives: Breast cancer is the most common malignancy among women worldwide. Vacuum-assisted breast biopsy (VABB) has emerged as a minimally invasive alternative to surgical excision, but it may cause post-biopsy scarring that could mimic or

Application of tomosynthesis for vertebral compression fracture diagnosis and bone healing assessment in fracture liaison services

Frontiers in Medicine, 2022
Early identification of vertebral compression fractures (VCFs) is crucial for successful secondary fracture prevention. Tomosynthesis, a low-dose tomographic imaging technique, may facilitate the evaluation and long-term follow-up of VCFs in patients ...

Detecting Breast Tumors in Tomosynthesis Images Utilizing Deep Learning-Based Dynamic Ensemble Approach

Computers, 2023
Digital breast tomosynthesis (DBT) stands out as a highly robust screening technique capable of enhancing the rate at which breast cancer is detected. It also addresses certain limitations that are inherent to mammography.

The Impact of Adding Digital Breast Tomosynthesis to BI-RADS Categorization of Mammographically Equivocal Breast Lesions

Diagnostics, 2023
Digital mammography (DM) is the cornerstone of breast cancer detection. Digital breast tomosynthesis (DBT) is an advanced imaging technique used for diagnosing and screening breast lesions, particularly in dense breasts.

Tomosynthesis-Detected Architectural Distortions: Correlations between Imaging Characteristics and Histopathologic Outcomes

Journal of Imaging, 2023
Objective: to determine the positive predictive value (PPV) of tomosynthesis (DBT)-detected architectural distortions (ADs) and evaluate correlations between AD’s imaging characteristics and histopathologic outcomes.

Online Geometric Calibration of a Hybrid CT System for Ultrahigh-Resolution Imaging

Tomography, 2022
A hybrid imaging system consisting of a standard computed tomography (CT) scanner and a low-profile photon-counting detector insert in contact with the patient’s body has been used to produce ultrahigh-resolution images in a limited volume in chest scans

Inter-plane artifact suppression in tomosynthesis using 3D CT image data

BioMedical Engineering OnLine, 2011
Background Despite its superb lateral resolution, flat-panel-detector (FPD) based tomosynthesis suffers from low contrast and inter-plane artifacts caused by incomplete cancellation of the projection components stemming from outside the focal plane.
