To further develop gene therapy for patients with glioblastomas, an experimental gene therapy protocol was established comprising a series of imaging parameters for (i) noninvasive assessment of viable target tissue followed by (ii) targeted application of herpes simplex virus type 1 (HSV-1) amplicon vectors and (iii) quantification of treatment effects by imaging. We show that viable target ti...

The spatial correlations between the brain's default mode network (DMN) and the brain regions known to develop pathophysiology in Alzheimer's disease (AD) have recently attracted much attention. In this paper, we compare results of different functional and structural imaging modalities, including MRI and PET, and highlight different patterns of anomalies observed within the DMN. Multitracer PET...

A multitracer technique has recently been developed in RIKEN using a heavy-ion-induced reaction with an intermediate energy of RIKEN Ring Cyclotron. Several kinds of tracer isotopes can be used simultaneously so that various parts of a sample could be simultaneously tested. However, with the present technology, a sample has to be decomposed to confirm the kind of tracer isotope in each part. Mu...

Alzheimer's disease is characterized by impaired glucose metabolism and demonstration of amyloid plaques. Individual positron emission tomography tracers may reveal specific signs of pathology that is not readily apparent on inspection of another one. Combination of multitracer positron emission tomography imaging  yields promising results. In this paper, 57 Alzheimer's disease neuroimaging ini...

ABSTRACT We introduce the AbacusHOD model and present two applications of AbacusSummit simulations to observations. is a Halo Occupation Distribution (HOD) framework written in Python that particle-based, multitracer, highly generalized, efficient. It designed specifically with multitracer/cosmology analyses for next-generation large-scale structure surveys mind, takes advantage volume precisio...

UNLABELLED Automated voxel-based or predefined volume-of-interest (VOI) analysis of rodent small-animal PET data is necessary for optimal use of information because the number of available resolution elements is limited. We have mapped metabolic ((18)F-FDG), dopamine transporter (DAT) (2'-(18)F-fluoroethyl(1R-2-exo-3-exe)-8-methyl-3-(4-chlorophenyl)-8-azabicyclo[3.2.1]-octane-2-carboxylate [(18...
