Brain perfusion SPECT is a non-invasive nuclear medicine imaging technique that allows regional CBF evaluation. The technique includes four main components: the CBF radiotracers (radiopharmaceuticals)‚ instrumentation‚ image reconstruction‚ and CBF quantification. 1.1.1 CBF radiotracers The inert gas xenon 133 is one of the most important and classical radiotracers for CBF measurement in absolute units using SPECT []. Nevertheless‚ the poor spatial resolution and the requirement for dedicated instrumentation

They have learned that inside the brain there is a synapse or an area that is open between the axon of a nerve and the dendrite of another nerve. The synapse entails the neurotransmitters‚ mitochondria‚ postsynaptic ending that has receptors sites for the neurotransmitters‚ and a synaptic cleft. When alcohol is consumed and reaches the brain‚ it can alter neuron membranes‚ ion channels‚ enzymes‚ and receptors

Doctor- “A brain-eating amoeba” is just as horrific as it sounds‚ is a parasite that can enter the brain and lead to deadly inflammation of the brain. Naegleria fowleri makes its way into our body by entering the brain through the nose typically when someone goes underwater. It infects the brain‚ leading to meningitis‚ which eventually causes death. The infected person normally dies within a period of 2 weeks.“Naegleria Fowleri” is the genus and species name of the amoeboflagellate. This amoeba causes
