Enhanced analysis of gating latency in 0.35T MR‐linac through innovative time synchronization of a motion phantom and plastic scintillation detector

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aims to evaluate how different gantry angles, breathing rates (BPM), cine image speeds, and tracking algorithms affect beam on/off latency and the subsequent impact on target dose for a 0.35T MR‐Linac with a 6 MV FFF beam.

Energy dependence of the GAFCHROMIC LD‐V1 in the diagnostic radiographic modalities

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract The GAFCHROMIC LD‐V1 radiochromic film is widely used in dosimetry because it can provide high‐resolution two‐dimensional dose distributions without processing. This study aimed to evaluate the response characteristics at different effective energies, from the low‐energy range of mammography to the high‐energy range of computed tomography. Net

Clinical characterization of Collagen XII‐related disease caused by biallelic COL12A1 variants

open access: yesAnnals of Clinical and Translational Neurology, Volume 12, Issue 3, Page 602-614, March 2025.
Abstract Objective While there have been several reports of patients with dominantly acting COL12A1 variants, few cases of the more severe recessive Collagen XII‐related disorders have previously been documented. Methods We present detailed clinical, immunocytochemical, and imaging data on eight additional patients from seven families with biallelic ...

Blood exosome connexins and small RNAs related to demyelinating disease activity

open access: yesAnnals of Clinical and Translational Neurology, Volume 12, Issue 3, Page 538-555, March 2025.
Abstract Objectives To assess blood exosome (Ex)‐connexin (Cx)43 (encoded by GJA1) and its truncated isoforms in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD), which show distinct alterations in astroglial Cx43. Methods Serum Exs from 48 patients with MS (34 relapsing–remitting, 14 secondary‐progressive), 35 with NMOSD, 20 ...

An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis

open access: yesAnnals of Clinical and Translational Neurology, Volume 12, Issue 4, Page 686-700, April 2025.
By applying the tensor model, we analysed lesion orientation and the directionality of lesion expansion/contraction in multiple sclerosis. Each lesion is summarized as an ellipsoid, and the tensor model is applied to calculate lesion anisotropy. From the top to the bottom white matter atlas, surface‐in gradient segmentation and venous atlas used in the
