Advancements in neuroimaging technologies has lead to the emergence of multimodal hybrid techniques that combine innate advantages of the modalities used in the setup.
Most notable bimodal and trimodal hybrids ARE:
- Single Photon Emission Computed Tomography / Computed Tomography (SPECT/CT) [O’Connor 2006]
- Positron Emission Tomography / CT (PET/CT) [Townsend 2008]
- PET / Magnetic Resonance Imaging (PET/MRI) [Pichler et al. 2008]
- Electroencephalography / functional Magnetic Resonance Imaging (EEG/fMRI) [Valdes‐Sosa et al. 2008]
- Magnetoencephalograph / fMRI (MEG/fMRI) [Plis et al. 2010]
- EEG / Near Infrared Spectroscopy (EEG/NIRS) [von Lühmann et al. 2016]
- Magnetic Resonance / PET / EEG (MR/PET/EEG) [Guerra et al. 2018]
- MR/PET/CT [Stolzmann et al. 2013]
More emerging modalities such as Optical Imaging, Diffusion Tensor Imaging (DTI), functional connectivity Photoacoustic Tomography (fcPAT) [Anderson et al. 2017] are candidates to e hybridized with existing systems.
