Abstract
Context: Data on T1 and T2 mapping reference range on 3T MRI scanners in healthy Indian population is scarce.
To find the reference range of T1 and T2 myocardial mapping in healthy Indian population relative to age and gender and to find specific reference range for cardiac base, mid and apex.
Settings and Designs: Prospective observational study.
Methods and Materials: 50 subjects were chosen after exclusion of cardiovascular morbidities and history of COVID-19 infection and underwent myocardial T1 and T2 mapping at 3T Philips Ingenia scanner.
Statistical Analysis Used: SPSS v23 (IBM Corp.) was used for data analysis
Results and Conclusions: Mean myocardial T1 and T2 mapping values at 3T scanner were 1269.96 ± 37.90 and 47.21 ± 1.47 ms respectively. There was no correlation or association found between T1 and T2 mapping values with age. Mean T1 mapping values were higher in females (1287.62 ± 46.55ms). No statistically significant difference was found in T2 mapping values between the genders. The meanT1 values in base, mid and apical segments were 1255.08 ± 39.90, 1260.91 ± 47.97 and 1293.88 ± 49.95 ms respectively. The mean T2 values in base, mid and apical segments were 46.05 ± 2.81, 46.04 ± 2.24 and 49.98 ± 2.53 ms respectively. The mean T1 and T2 values in apical segment were higher as compared to mid and base.
