Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Hydrogel‐based drug delivery systems for intracerebral hemorrhage with therapeutic advances and emerging roles of the bone–brain axis

Interdisciplinary Medicine, EarlyView.
Hydrogel‐based drug delivery systems offer a promising approach for treating intracerebral hemorrhage (ICH) by overcoming blood‐brain barrier limitations, enabling precise, sustained release of neuroprotective and anti‐inflammatory agents. These systems enhance treatment efficacy, but challenges remain in biosafety, drug penetration, and scalability ...

Quantification of Tricuspid Valve Regurgitation With 2D and 4D‐Flow MRI: Comparison of Different Methods in Adult Patients With Ebstein's Anomaly

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Ebstein's anomaly (EA) is a congenital heart disorder involving tricuspid valve dysplasia and right heart abnormalities resulting in severe tricuspid regurgitation (TR). Multiple techniques assess regurgitation severity, but their correlation with EA severity markers remains unclear. Purpose To compare MRI techniques for quantifying

Performance of Free‐Running Cardiac and Respiratory Motion‐Resolved Whole‐Heart 5D MRI in Congenital Heart Disease Patients Using a Gadolinium Enhanced Fast‐Interrupted Steady‐State Sequence

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The performance of 5D imaging in CHD has been previously demonstrated using ferumoxytol rather than gadolinium. Purpose To evaluate the performance of gadolinium enhanced 5D MRI relative to 2D and 3D MRI in CHD patients. Study Type Retrospective.

Postprandial Changes in Thoracic Aortic Flow Detected by 4D Flow MRI May Influence Study Results

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background While there is a growing body of data using 4D flow MRI to distinguish between normal and abnormal blood flow values in the thoracic aorta, the extent of physiological variation or lack thereof is potentially undervalued. Physiological processes such as postprandial changes to hemodynamics might influence data, normal values, follow‐
