T2* normal values
WebThe T2 value was assessed in all 16 myocardial segments and the global value was the mean. Results: The global T2 value averaged across all subjects was 52.2 ± 2.5 ms (range: 47.0-59.9 ms). Inter-study, intra-observer, and inter-observer reproducibility was good (coefficient of variation < 5%). 3.6% of the segments was excluded because of ... WebBackground: Myocardial native T1 and T2 mapping are promising techniques for quantitative assessment of diffuse myocardial pathologies; however, due to conflicting data regarding normal values, routine clinical implementation of this method is still challenging. Methods: To evaluate this situation during daily clinical practice the characteristics of normal …
