In emission tomography, the spread of regional tracer uptake to surrounding areas caused
by limited spatial resolution of the tomograph must be taken into account when quantitating …

The purpose of this study was to compare the calibration of PET scanners and their cross
calibration to peripheral devices in a multicenter study. Methods: Twenty-three dedicated PET …

BACKGROUND: The cannabinoid CB 1 receptor agonist Δ 9 -THC has been suggested for
treatment of Tourette syndrome (TS). Based on animal studies, the CB 1 antagonist [ 123 I]…

We will use the method introduced in the first part of our paper (see [ 5 ]) to give the best
lower estimate of ∥f - B n f ∥ for the Bernstein polynomial operators by means of a modified …

The germination and sporeling development of Fontinalis squamosa Hedw. was investigated
at 3, 14, and 20 C and five light intensities. The sporeling type most closely resembles that …

A multi-centre trial using PET requires the analysis of images acquired on different systems
We designed a multi-centre trial to estimate the value of 18F-FLT-PET to predict response to …

Quantitative determination of activity concentration has always been regarded as a goal of
PET scanner design. Therefore, a linear response with respect to activity concentration is …

The differentiation stage of the caulonema in Funaria hygrometrica protonema is distinguished
from the chloronema stage by three additional protein bands (CSP) in the soluble protein …

A proposal is made for the test conditions to evaluate PET count rate performance. This
performance depends in a complex manner on the spatial distribution of activity and scattering …

Media isolated from growing cell cultures (conditioned media) contain «viability factors»
which promote the survival of plant cells plated at low density. We developed a procedure for …
