✦ Synopsis

A multislice real-time imaging technique is described which can provide continuous visualization of the entire left ventricle under resting and stress conditions. Three dynamically adjustable slices containing apical, mid, and base short axis views are imaged 16 times/sec (48 images/sec), with each image providing 3.12 mm resolution over a 20 cm field of view. Initial studies indicate that this technique is useful for the assessment of LV function by providing simultaneous real-time visualization of all 16 wall segments. This technique may also be used for stress LV function and, when used in conjunction with contrast agents, myocardial perfusion imaging. Magn Reson Med 45: 371-375, 2001.

## Abstract Current methods for MRI of infarcted myocardium require ECG‐gating and breath‐holding during contrast‐enhanced segmented __k__‐space inversion‐recovery (IR) imaging. However, ECG‐gating can be problematic in MRI, and breath‐holding can be difficult for some patients. This work demonstra
