The impact of ZTE-based MR attenuation correction compared to CT-AC in 18F-FBPA PET before boron neutron capture therapy

Scientific Reports
Tumor-to-normal ratio (T/N) measurement of 18F-FBPA is crucial for patient eligibility to receive boron neutron capture therapy. This study aims to compare the difference in standard uptake value ratios on brain tumors and normal brains using PET/MR ZTE ...

Effectiveness and safety of baricitinib for juvenile idiopathic arthritis associated uveitis or chronic anterior antinuclear antibody positive uveitis

Arthritis Care &Research, Accepted Article.
Objectives Evaluate the efficacy and safety of baricitinib in paediatric patients with active JIA‐U or chronic anterior ANA‐positive uveitis, who had an inadequate response to MTX or bDMARDs. Methods JUVE‐BRIGHT was an open‐label, active‐controlled, Phase‐3 multicentre trial which utilized a novel design, including 1:1 randomization to an active ...

Dose Optimization in TOF-PET/MR Compared to TOF-PET/CT.

PLoS ONE, 2015
PurposeTo evaluate the possible activity reduction in FDG-imaging in a Time-of-Flight (TOF) PET/MR, based on cross-evaluation of patient-based NECR (noise equivalent count rate) measurements in PET/CT, cross referencing with phantom-based NECR curves as ...

Regional Accuracy of ZTE-Based Attenuation Correction in Static [18F]FDG and Dynamic [18F]PE2I Brain PET/MR [PDF]

Frontiers of Physics, 2018
Accurate MR-based attenuation correction (MRAC) is essential for quantitative PET/MR imaging of the brain. In this study, we analyze the regional bias caused by MRAC based on Zero-Echo-Time MR images (ZTEAC) compared to CT-based AC (CTAC) in static and ...

Beyond Inflammation: Why Understanding the Brain Matters in Inflammatory Arthritis

Arthritis Care &Research, EarlyView.
Persistent pain remains a major challenge in inflammatory arthritis, even when joint inflammation is well controlled. Pain and associated symptoms such as fatigue cannot be explained by peripheral inflammation alone but reflect altered central pain processing. These changes may arise through “top‐down” mechanisms, reflecting pre‐existing dysfunction in
