Comparison between simultaneously acquired arterial spin labeling and 18F-FDG PET in mesial temporal lobe epilepsy assisted by a PET/MR system and SEEG

NeuroImage: Clinical, 2018
Objective: In the detection of seizure onset zones, arterial spin labeling (ASL) can overcome the limitations of positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG), which is invasive, expensive, and radioactive.

Low‐Field MRI as a Multiparametric Tool for Large Engineered Tissue Characterization

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Advances in 3D bioprinting have enabled the fabrication of large and complex engineered tissues, but their increasing size demands non‐invasive tools for monitoring structure, maturation, and perfusion. Magnetic Resonance Imaging (MRI) offers unique multiparametric capabilities, yet high‐field systems remain costly and inaccessible for most ...

Grading of skull base meningiomas by combined perfusion: arterial spin labeling and T2* dynamic susceptibility perfusion

The Egyptian Journal of Radiology and Nuclear Medicine
Background Conventional MRI has no distinction between high- and low-grade meningiomas, which has a crucial for choice of therapeutic plan, especially skull base meningiomas which need more meticulous endoscopy-approached surgery.

Neuroimaging of the ictal–interictal continuum: Where do we stand? A systematic review and meta‐analysis of current evidence

Epilepsia Open, EarlyView.
Abstract Objective Patterns within the ictal–interictal continuum (IIC) are frequently encountered in critically ill patients undergoing continuous electroencephalographic studies and may reflect ongoing ictal activity or secondary brain injury. Peri‐ictal neuroimaging abnormalities (PNA) have been described in association with status epilepticus (SE),

Comparison of Resting-State Brain Activation Detected by BOLD, Blood Volume and Blood Flow

Frontiers in Human Neuroscience, 2018
Resting-state brain activity has been widely investigated using blood oxygenation level dependent (BOLD) contrast techniques. However, BOLD signal changes reflect a combination of the effects of cerebral blood flow (CBF), cerebral blood volume (CBV), as ...
