Key Findings in SPECT and PET in Alzheimer's disease

The functional neuroimaging modalities of single photon emission computed tomography (SPECT) and positron emission tomography (PET) may also be used in the diagnosis Alzheimer's.[1] In some cases, the ability of SPECT to differentiate Alzheimer's disease from other possible causes in a patient already known to be suffering from dementia may be superior to attempts to differentiate the cause of dementia cause by mental testing and history.[2] A new technique known as "PiB PET" has been developed for directly and clearly imaging beta-amyloid deposits in vivo using a contrasting tracer that binds selectively to the Abeta deposits.[3][4][5] Another recent objective marker of the disease is the analysis of cerebrospinal fluid for amyloid beta or tau proteins.[6] Both advances (neuroimaging and cerebrospinal fluid analysis) have led to the proposal of new diagnostic criteria.[7][8]
