Impact of Diffusion‐Weighted Magnetic Resonance Imaging Parameters on Diagnostic Accuracy for Thyroid Nodules: A Systematic Review and Meta‐Analysis

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Surgery is the gold standard to differentiate benign from malignant thyroid nodules, but it is invasive and often unnecessary in indeterminate cases. Diffusion‐Weighted MRI (DW‐MRI) has emerged as a promising, non‐invasive tool, though its accuracy and the impact of acquisition parameters remain unclear.

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Analysis of Upper Airway Morphology Using Four‐Dimensional Dynamic MRI With Active Deep Learning‐Based Automatic Segmentation

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Upper‐airway morphology changes during breathing can be captured with cine 4D MRI. Active‐learning nnU‐Net reduces manual labeling while maintaining accuracy. Purpose For automatic upper airway segmentation on free‐breathing cine 4D MRI using active learning and quantifying dynamic changes under two mouth positions.

Open or closed: Experience of head and neck radiotherapy masks – A mixed‐methods study

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 74-84, March 2025.
Patients with head and neck cancer received radiotherapy alternately with an open and a closed mask. The closed mask was perceived as more confining and restrictive, but it was also considered to make it easier to quickly achieve the correct position, while the open mask was perceived as less stable, although it reduced the feeling of claustrophobia ...
