An MRI pulse sequence is a set of specific radiofrequency pulses, gradient pulses, and data acquisition parameters designed to generate a desired contrast and spatial resolution in MRI images. It is crucial for differentiating between various tissue types and pathologies, optimizing diagnostic accuracy and efficiency in medical imaging.

MRI Pulse Sequence

Radiofrequency pulses are short bursts of electromagnetic energy used primarily in MRI to manipulate the alignment of hydrogen nuclei within the body, facilitating the generation of detailed internal images. These pulses are crucial for exciting the nuclei and enabling the subsequent relaxation process, which is measured to produce diagnostic images.

Tissue types are groups of similar cells that perform a common function, and they are crucial in the organization of multicellular organisms. The four primary tissue types in animals are epithelial, connective, muscle, and nervous tissues, each with distinct structures and roles in maintaining homeostasis and enabling complex biological processes.
