NEUROPSIQUIATRIA: PET Y SPECT

SPECT/PET Simulation Algorithm

process of setting up the system to be simulated; c) to implement a server architecture which enables users from other research facilities to employ this tool to support their own research projects; and d) to distribute the computational very expensive process of simulating (and reconstructing) data automatically over a set of available computers. Whereas the MC and reconstruction codes are wri...

[PET and SPECT in epilepsy].

Epilepsy is one of the most frequent chronic neurological disorders, affecting 1-2% of the population. Patients with complex partial drug resistant episodes may benefit from a surgical treatment consisting in the excision of the epileptogenic area. Localization of the epileptogenic area was classically performed with video-EEG and magnetic resonance (MR). Recently, functional neuroimaging studi...

Emission Tomography: SPECT and PET Tomografia por Emissão: SPECT e PET

Emission tomography is a medical image modality that utilizes molecules labelled with radionuclides, the radiopharmaceuticals, to obtain functional information about specific tissues or systems. In SPECT, Single Photon Emission Computerized Tomography, the radionuclide decays by emitting one or more photons, while in PET, Positron Emission Tomography, the radionuclide emits a positron, in order...

Basics of SPECT , PET and PET / CT Imaging

In the diagnostic imaging two kinds of modalities can be differentiated. On one side the anatomical imaging, providing a very accurate visualization of the intern structures of the human body; and the functional imaging, which is aimed to quantify the physiological processes taking place inside the human body without influencing them. One of the most widely spread practices used for this purpos...
