pulse sequences

Pulse sequences are carefully timed series of radiofrequency signals used in MRI scans to manipulate the alignment of hydrogen atoms in the body. By controlling these pulses and their timing, MRI machines can highlight different tissues, create detailed images, and gather specific information about the body's internal structures. Think of it as a well-choreographed dance where each move (pulse) is designed to produce the clearest picture for diagnosis. The sequence's design affects the image quality, contrast, and the type of information obtained during the scan.
