Dopamine Transporter Imaging‐Based Radiomics for Predicting 4‐Year Motor Progression (Unified Parkinson's Disease Rating Scale Part III) in Parkinson's Disease

iRADIOLOGY, EarlyView.
Magnetic resonance imaging (MRI)‐guided dopamine transporter (DAT) radiomics combined with machine learning showed promising performance for predicting 4‐year motor progression in Parkinson's disease. Ensemble voting fusion markedly improved discrimination compared with individual base models, with stable predictive features mainly derived from ...

Mapping Neurodegenerative Changes in Clinically Uncertain Parkinsonian Syndrome Patients Using Fast MR Spin TomogrAphy in Time‐Domain (MR‐STAT) Relaxometry at 3T

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background MR Spin TomogrAphy in Time‐domain (MR‐STAT) enables accelerated multiparametric relaxometry (T1/T2). Previous relaxometry studies predominantly compared Parkinson's disease patients with healthy controls (HC). The potential of relaxometry to distinguish neurodegenerative from non‐neurodegenerative parkinsonism in clinically ...

Prone Breast Radiotherapy on the MR‐Linac: A Technical Note on Skin‐Couch Contact Dose Effects

Journal of Medical Radiation Sciences, EarlyView.
This retrospective planning study evaluated the dosimetric effects of skin‐couch contact during prone APBI on a 1.5 T MR‐Linac by comparing treatment plans calculated with and without a magnetic field. While the presence of the magnetic field increased overall superficial skin dose, it consistently reduced dose at the skin‐couch contact region ...
