    Binding kinetics of11c-n-methyl piperidyl benzilate (11c-nmpb) in a rhesus monkey brain using the cerebellum as a reference region

    The binding kinetics of11C-N-methyl piperidyl benzilate (11C-NMPB) in rhesus monkey brain were studied using animal positron emission tomography (PET) (SHR2000). This study is intended to assess the validity of t...

    Effects of anesthesia upon18F-FDG uptake in rhesus monkey brains

    The kinetics of18F-fluorodeoxyglucose (18F-FDG) in the monkey brain were monitored, and comparisons were made between the conscious state and when under ketamine and pentobarbital anesthesia. Rhesus monkeys were ...

    Clinical application of a new method that segments the region of interest into multiple layers for RF amplitude histogram analysis in the cirrhotic liver

    We used texture analysis in conjunction with an alternative method of analyzing the amplitude histogram using a radiofrequency (RF) signal to differentiate ultrasonograms of normal and cirrhotic livers. This m...

    Different sensitivities to competitive inhibition of benzodiazepine receptor binding of11C-iomazenil and11C-flumazenil in rhesus monkey brain

    Thein vivo binding kineties of11C-iomazenil were compared with those of11C-flumazenll binding in rhesus monkey brain. The monkey was anesthetized with ketamine and intravenously injected with either11C-iomazenil ...

    Electrogastrographic power ratio in humans is not related to changes in antrum-skin distance but to antral motility

    It is not clear whether the power increase in electrogastrography (EGG) after meal or water ingestion reflects increases in gastric motility or gastric distension bringing the stomach closer to the electrodes...
