Apathy has been reported to occur after subthalamic nucleus stimulation, a treatment of motor
complications in advanced Parkinson’s disease. We carried out a prospective study of the …

In this work, we evaluated three iterative deconvolution algorithms and compared their
performance to partial volume (PV) correction based on structural imaging in brain positron …

In emission tomography, image reconstruction and therefore also tracer development and
diagnosis may benefit from the use of anatomical side information obtained with other imaging …

Despite intense interests in developing blood measurements of Alzheimer’s disease (AD),
the progress has been confounded by limited sensitivity and poor correlation to brain …

PET imaging of D 2 receptors or 18 F-l-dopa metabolism are reference protocols to follow
and study neurodegenerative diseases, but the accuracy of striatal PET imaging is limited by …

Nine previously proposed segmentation evaluation metrics, targeting medical relevance,
accounting for holes, and added regions or differentiating over- and under-segmentation, were …

Patient motion during positron emission tomography scanning can affect the accuracy of the
data analysis in two ways: 1) movement occurring during emission data acquisition alters …

Monte Carlo-based PET simulators are powerful tools for accurately generating projections
of tracer distributions for given scanner specifications and attenuating media distributions. …

The reconstruction of dynamic PET data is usually performed using filtered backprojection
algorithms (FBP). This method is fast, robust, linear and yields reliable quantitative results. …

Introduction There is increasing evidence that phosphorylated tau (P‐tau181) is a specific
biomarker for Alzheimer's disease (AD) pathology, but its potential utility in non‐White patient …
