Abstract:
Gradient-echo pulse sequences are a valuable adjunct to the standard spin-echo sequences used for MR imaging of the brain and spine. Gradient-echo techniques enhance the signal of flowing fluids and increase the conspicuity of vascular lesions. They also increase the sensitivity of MR for chronic hemorrhage and calcification. Finally, steady-state techniques produce a myelographic effect to help evaluate degenerative diseases of the spine.
