Allogeneic Bone Marrow‐Derived Mesenchymal Stem Cells for Parkinson's Disease: A Randomized Trial

open access: yesMovement Disorders, EarlyView.
Abstract Background Neuroinflammation contributes to Parkinson's disease (PD) progression and motor dysfunction. Allogeneic human mesenchymal stem cells (allo‐hMSCs) may reduce neuroinflammation and improve motor symptoms. Objectives To evaluate the efficacy of repeated intravenous doses of 10 × 106/kg allo‐hMSCs in improving motor symptoms in patients

Mimicking focused ultrasound with a loop coil in acoustic radiation force imaging

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To enable development of MR‐acoustic radiation force imaging (MR‐ARFI) methods for targeting ultrasound in human subjects without the regulatory, acoustic, or hardware challenges associated with actual transcranial ultrasound setups. Methods MR‐ARFI is a phase‐contrast imaging method that measures focal tissue displacement produced by ...

MR‐ARFI to evaluate intensity variability and enhance targeting of FUS: A brain study in rats

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Inconsistencies in focused ultrasound (FUS) transducer positioning and skull‐induced aberrations can reduce the targeting accuracy and cause inconsistencies in the intensity delivered during FUS neuromodulation procedures. This study aimed to evaluate the use of MR‐acoustic radiation force imaging (MR‐ARFI) in improving the targeting ...

Alternating‐contrast single‐shot spiral MR‐ARFI with model‐based displacement map reconstruction

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To improve single‐shot spiral MR‐Acoustic Radiation Force Imaging (MR‐ARFI)'s robustness to dynamic phase errors and evaluate it in non‐human primates (NHPs) with a low‐f‐number transducer. Methods A single‐shot spiral MR‐ARFI pulse sequence with 2 mm in‐plane resolution and alternating displacement phase contrast was implemented to ...
