Myocardial tagging and strain analysis at 3 Tesla: Comparison with 1.5 Tesla imaging

Purpose To determine whether imaging at 3 T could improve and prolong the tag contrast compared to images acquired at 1.5 T in normal volunteers, and whether such improvement would translate into the ability to perform strain measurements in diastole. Materials and Methods Normal volunteers ( N = 13) were scanned at 1.5 T (GE Signa CV/i) and 3.0 T (GE VH/i). An ECG‐triggered, segmented k‐space, spoiled‐gradient‐echo grid‐tagged sequence was used...
