Theory of high-speed MR imaging of the human heart with the selective line acquisition mode.
Selective line acquisition mode (SLAM) reduces magnetic resonance imaging time by a factor n relative to conventional techniques. Seventeen patients with cardiac disease and three volunteers were examined with SLAM and two-frame interpolation (2FI). SLAM images were sharper than 2FI images and showed well-defined endocardial borders. SLAM is best suited for fast imaging of moving objects, such as the heart, confined to 1/n of the field of view.
