A nuclear magnetic resonance (NMR) technique for producing multiplexed NMR echo trains. The present invention results in the placement of discrete copies of the original spin-echo in a line along k-space. Utilizing a conventional NMR apparatus, a longitudinal magnetic field is first generated. Next a train of NMR spin-echoes is created by imprinting a repetitive pattern on the longitudinal magnetization. This pattern is composed of a sum of complex exponentials. The spins are then evolved and observed in an uninterrupted readout period. The result is an NMR pulse sequence (10) which splits the spin-echo into a series of spin-echoes thereby permitting the sampling of k-space in a single data acquisition. In the preferred embodiment, the multiplexed echo train technique of the present invention is applied to single-shot magnetic residence imaging (MRI) to permit rapid collection of data, fast screening, and two or three-dimensional imaging in clinically practical times.
