There is growing interest in the human sodium/iodide symporter (NIS) gene both as a molecular imaging reporter gene and as a therapeutic gene. Here, we show the feasibility of radioisotope therapy of neuroendocrine tumors. As a separate application o

We present a novel imaging technique based on the translation of the object through the field of view of one or more stationary multipinhole detectors. This new imaging method is called Translatory SPECT or T-SPECT. The benefits of T-SPECT lie in its

The authors present a novel SPECT imaging technique for small animal research based on multipinhole collimation. This new method is an extension of single-pinhole tomography and combines high resolution with increased system sensitivity. This paper d

In the framework of the German Plant Phenotyping Network (DPPN) we developed a novel PET scanner for imaging plants and crops. The observation of the carbon transport within the plant becomes possible by using 11CO2 as PET tracer. The use of the rath

The aim of this study was to show that the multipinhole technique (high-resolution single-photon emission computed tomography [HiSPECT]) is suitable for dynamic imaging of both biodistribution and temporal uptake behavior of radiolabeled cationic lip

In this study, we assess the impact of the reference tissue (frontal cortex, parietal cortex, cerebellum) on the magnitude of the binding potential obtained for the D2 receptor ligands [18F]N-methyl-benperidol and [123I]iodobenzamide in the rat stria

The list-mode format is particularly suitable for high-resolution tomographic systems, where the precision of the data have not to be compromised, but also claims new demands on data processing and image reconstruction. We apply a ray-tracing algorit

Conventionally, positron emission tomography data are sorted into sinograms prior to image reconstruction. This leads to a loss of spatial and temporal resolution due to histogramming of events. An alternative data representation is the so-called lis

Molecular imaging calls for imaging systems with both high resolution and high sensitivity. In small-animal SPECT high resolution is typically achieved using pinhole collimation. In order to improve the sensitivity of single-pinhole systems we employ
