摘要: Magnetic resonance signals for imaging species having short spin-spin relaxation times (T₂) are obtained without the need a refocusing lobe. A series of RF excitation pulses applied to with magnetic being detected after each pulse is applied. The then combined provide signals. In one embodiment, half conventional slice-selective slewed zero. Contrast between imaged T₂ and longer can be enhanced by first applying an signal sufficient amplitude excite but insufficient whereby tipped signal. gradient dephase nuclei species. from
