Gradient Echo Sequences are a type of MRI technique that utilizes gradient fields to create images by rephasing spins after a gradient-induced dephasing, allowing for rapid imaging with good contrast between different tissues. This method is particularly useful for visualizing structures with high water content and for applications requiring fast acquisition times, such as functional MRI and dynamic contrast-enhanced studies.

MRI technique

Gradient fields represent a vector field where each vector points in the direction of the greatest rate of increase of a scalar field, with the magnitude of the vector corresponding to the rate of increase. They are crucial in understanding how changes in one variable affect changes in another, often used in physics and engineering to model forces, heat, and fluid flow.

Functional MRI (fMRI) is a neuroimaging technique that measures brain activity by detecting changes in blood flow, offering insights into brain function and connectivity. It provides high spatial resolution images and is widely used in both clinical and research settings to study brain disorders and cognitive processes.
