OpenMRF : A Modular, Vendor‐Neutral Open‐Source Framework for Magnetic Resonance Fingerprinting Using Pulseq

ABSTRACT Purpose Widespread adoption and methodological advancement of magnetic resonance fingerprinting (MRF) are limited by the lack of unified, reproducible implementation frameworks and fragmented open‐source tools. To address these barriers, we introduce OpenMRF—a comprehens...

Optimizing coronary CT angiography in patients with delayed contrast arrival using a free-breathing, high-threshold bolus-tracking protocol

OBJECTIVE: To investigate the performance of a free-breathing coronary computed tomography angiography (CCTA) protocol using a high-threshold bolus-tracking strategy in improving coronary enhancement and diagnostic visualization in patients with delayed contrast arrival. MATERIAL...

Application of 80 kVp combined with deep learning reconstruction algorithm in overweight patients coronary CT angiography: reduced radiation dose and contrast agent dose

<title>Abstract</title> Background: Coronary CT angiography (CCTA) has become a key imaging technique for clinical screening of coronary artery disease (CAD). Overweight patients have a higher prevalence of CAD, however, they face increased risks of radiation exposure and contras...

FOCUS: a feature optimization and cascaded unified screening strategy for computer-aided pathology-based glioma molecular subtype classification

Abstract Background Accurate classification of Isocitrate Dehydrogenase (IDH) mutation status is crucial for the diagnosis and treatment of adult-type diffuse gliomas as defined by the 2021 World Health Organization (WHO) Classification. However, conventional histological and mol...

Clinical application of MR-Only in cyberknife stereotactic radiotherapy for brain metastases: a feasibility study

Due to the limited number of studies on MR-only stereotactic radiotherapy (SRT) for brain metastases using CyberKnife in the literature, this study systematically evaluates the dose calculations and image guidance accuracy of synthetic CT (sCT) and sCT-derived digital reconstruct...
