Neuroimaging Techniques

Magnetic Resonance Imaging (MRI) employs strong magnetic fields and radio waves to generate cross-sectional images of the brain and other body parts.

Computed Tomography (CT) is commonly used for diagnosing brain tumors, strokes, and skull fractures due to its rapid image acquisition and ability to detect structural abnormalities.

Positron Emission Tomography (PET) utilizes radioactive tracers to measure regional cerebral blood flow and metabolic activity, providing insights into brain function.

Electroencephalography (EEG) measures electrical signals produced by the brain, allowing for the study of brain activity, sleep patterns, and seizure disorders.

PET-MRI combines the anatomical detail of MRI with the functional information provided by PET, enabling comprehensive analysis of brain structure and function.

Computed Tomography (CT) involves ionizing radiation, which can be a concern for repeated or excessive scans, particularly in younger patients.

Diffusion Tensor Imaging (DTI) is a specialized MRI technique that measures the diffusion of water molecules in the brain, providing insights into the structural connectivity of neural pathways.

Transcranial Magnetic Stimulation (TMS) uses magnetic pulses to stimulate specific brain regions, allowing researchers to study the effects of brain stimulation on behavior and cognition.

Magnetoencephalography (MEG) detects and records magnetic fields generated by electrical activity in the brain, providing information about the timing and location of neural processes.

Functional Magnetic Resonance Imaging (fMRI) excels in capturing rapid changes in brain activity over time, providing high temporal resolution for studying dynamic brain processes.

Positron Emission Tomography (PET) employs radioactive tracers that bind to specific molecules in the brain, enabling the study of neurotransmitter systems, receptor binding, and metabolic processes.

Electroencephalography (EEG) records electrical signals generated by the brain in real-time, allowing researchers to study brain activity during cognitive tasks, sleep, and epileptic seizures.

fMRI-CT combines the anatomical detail of CT with the functional information provided by fMRI, enabling comprehensive analysis of brain structure and function.

Diffusion Tensor Imaging (DTI) has relatively low spatial resolution compared to other neuroimaging techniques, limiting its ability to resolve fine anatomical details.

Diffusion Tensor Imaging (DTI) is a specialized MRI technique that measures the diffusion of water molecules in the brain's white matter, providing insights into the structural connectivity of neural pathways.
