摘要:
The present invention provides a labelled acyl-L-carnitine, which is an acyl-L-carnitine, a salt thereof or a derivative thereof, of which carbon group is labelled with a radionuclide or a stable isotope. It is possible to diagnose human diseases falling under acyl-carnitine metabolic syndrome, or human diseases due to structural/functional disorder of the brain by measuring the behavior of the labelled acyl-L-carnitine in various tissues or a biological sample from a subject administered with one or more kinds of the labelled acyl-L-carnitines.
摘要:
Methods and reagents for transition metal-promoted carbonylation via isocyanate using carbon-isotope labeled carbon monoxide are provided. The resultant carbon-isotope labeled compounds are useful as radiopharmaceuticals, especially for use in Positron Emission Tomography (PET). Associated kits for PET studies are also provided.

摘要:
The present invention provides a labelled .beta.-cyano-L-alanine and a .gamma.-cyano-.alpha.-aminobutyric acid, of which cyano group carbon is labelled with radionuclide .sup.11 C or .sup.14 C, or stable isotope .sup.13 C. The present invention also provides a labelled amino acids such as asparagine, asparatic acid, DABA, GABA, glutamine and glutamic acid synthesized by using the labelled .beta.-cyano-L-alanine and the .gamma.-cyano-.alpha.-aminobutyric acid as an intermediate. The labelled amino acids are useful for in vivo imaging of tumors and brain functions.

摘要:
The invention relates to a system and method for enhancing image data obtained from a positron emission tomography (PET) scan. In various embodiments, the method comprises transforming an original image data set to provide a first modified image data set by performing a masked volume-wise principal component analysis (MVW-PCA) on the original image data set. The first modified image data set is then transformed to provide a second modified image data set by performing a masked volume-wise independent component analysis (MVW-ICA) on the first modified image data set, the second modified image data set thereby comprising enhanced image data.
