Pulsatility Assessment of Cerebral Perforating Arteries Using Submillimeter‐Resolution Dual‐VENC Phase‐Contrast MRI at 3T

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Dysfunction of cerebral perforating arteries is a major contributor to cerebral small vessel disease. Developing a reliable MRI technique for assessing cerebral perforating arteries on widely accessible 3T systems would be advantageous.

Analysis of Pulsatile Vessel Expansion in Healthy, COPD‐and PH‐Patients Using Dynamic Vessel Segmentation in Free‐Breathing Lung MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The pulsatile expansion of pulmonary vessels carries dynamic cardiopulmonary information that may reveal disease earlier than structural changes alone. Purpose To test (i) intra‐ and inter‐scan repeatability of dynamic vessel metrics in healthy subjects, and (ii) whether chronic obstructive pulmonary disease (COPD) and postcapillary

Towards Clinical Translation of Intravoxel Incoherent Motion MRI: Acquisition and Analysis Consensus Recommendations

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Intravoxel incoherent motion (IVIM) MRI allows for simultaneous assessment of tissue microcirculation (perfusion) and diffusion of water. In single‐center studies, IVIM has shown great potential for diagnosis, treatment outcome prediction, and treatment monitoring for many different diseases and organs.

Pre‐ and Post‐Interventional Hemodynamic Characterization of the Femoropopliteal Artery Using Vector Flow Imaging in Peripheral Arterial Occlusive Disease

Journal of Ultrasound in Medicine, EarlyView.
Objectives The femoropopliteal (FP) artery is the most frequently revascularized segment in peripheral artery disease (PAD), followed by the iliac segment. Wall shear stress (WSS) is a key local factor implicated in both atherosclerotic plaque formation and restenosis after angioplasty.

Considerations for Initiation and Maintenance of Foslevodopa/Foscarbidopa for Advanced Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background As Parkinson's disease (PD) progresses, motor fluctuations become increasingly difficult to manage with oral medications. Foslevodopa/foscarbidopa (LDp/CDp), delivered as a continuous 24‐h/day subcutaneous infusion, offers continuous levodopa delivery and stable plasma levodopa levels that reduce motor fluctuations. LDp/CDp has been
