4 июн. 2018 г. · T1 values are a few hundred milliseconds (ms) for most tissues examined. The following are approximate T1 values (ms) of several tissues for B 0 = 1.5 T.

T1 relaxation is the process by which the net magnetiztion (M) returns to its initial maximum value (Mo).

T2 relaxation always proceeds at a faster rate than T1 relaxation; thus the the T1 relaxation time is always longer than or equal to T2.

T1-weighted images are produced by using short TE and TR times. The contrast and brightness of the image are predominately determined by T1 properties of tissue ...

9 авг. 2024 г. · T1 relaxation time is defined as the time it takes for longitudinal magnetization to reach 63% of the original magnetization. So, T1 expresses ...

The T1 value of normal myocardium at 1.5T is approximately 950-1000 ms at 1.5T and 1100-1250 at 3.0T. Myocardial T1 is prolonged in most forms of pathology, ...

T1 values in both the gray and the white matter at the baseline visit were related to disease duration, suggesting that the T1 changes are clinically relevant.

7 июн. 2020 г. · T1 mapping is a magnetic resonance imaging technique used to calculate the T1 time of a certain tissue and display them voxel-vice on a parametric map.

30 нояб. 2016 г. · Elevated native T1 values can both be caused by myocardial oedema and fibrosis. In clinical practice, a presumable myocardial oedema zone in ...

T1 represents the time constant for recovery of equilibrium longitudinal magnetization. T1 values will vary depending on the molecular mobility and magnetic ...
