Single-photon emission computed tomography (SPECT)
The term SPECT refers to the mode of acquisition and indicates tomographic acquisition. We are therefore faced with the assessment by tomographic image of the passage of blood in the Central Nervous System. Although currently the CT and MRI are the most used central nervous system imaging tests, Nuclear Medicine offers unique information based on physiology and brain function.
They are imaging tests that can detect physiological changes before a structural alteration occurs, if this occurs. SPECT is fundamental in the study of the different pathologies of the Central Nervous System. The most important indication of this test is dementias and, among them, Alzheimer's, dementia with a great social and health impact in populations with high life expectancy. However, these tests can help in the diagnosis of various pathologies such as Bipolar Disorder, ADHD, among others.
