An image acquisition using a spoiled, gradient-recalled echo imaging pulse sequence is preceded by a magnetization preparation sequence which rapidly drives longitudinal magnetization to the steady-state equilibrium level established by the imaging pulse sequence. The preparation sequence includes an RF saturation pulse followed by a recovery period (T ) whose length is determined by the scan parameters of the imaging pulse sequence.

Preparation sequence for gradient echo MRI acquisition

An MRI system produces a series of real-time images by repeatedly acquiring image data and repeatedly reconstructing images from the acquired image data. The effective latency period between acquisition of the image data and display of the reconstructed images is minimized by acquiring image data in a reverse-centric view order in which low spatial frequencies are acquired last.
