Supports feasibility of ECG-gated T1 cardiac imaging; leaves open need for validation before clinical adoption.
In order to assess the true value of in vivo T 1 measurements of myocardial infarction in man a pulse sequence specifically designed for T 1 measurement with high precision has been gated with the cardiac cycle to produce gated T 1 images. The ability to obtain ECG-gated T 1 images of sufficient quality and in a sufficiently short time for clinical use has been demonstrated. The commercial system which has been modified has been shown to be particularly suitable for obtaining such images. This technique will be of value in assessing the use of in vivo T 1 measurement to identify abnormal pathology within the ventricular wall, particularly in patients with recent infarction.
