A pulse sequence is a specific order and timing of radiofrequency pulses and gradient magnetic fields used in magnetic resonance imaging (MRI) to manipulate the spin of protons in the body to generate images. These pulse sequences are tailored to produce different contrasts in the image, such as T1-weighted, T2-weighted, diffusion-weighted, or contrast-enhanced images, depending on the desired information to be obtained. Pulse sequences are a fundamental component of MRI technology and play a crucial role in the quality and diagnostic utility of the images produced. Researchers are continuously developing and optimizing pulse sequences to improve image quality, reduce scan times, and enhance the overall capabilities of MRI imaging.
