Since at 1.5 T, T1 fat= 260 ms and for most other tissues T1 > 500 ms. There fore the null point for the fat signal will occur sooner than the other tissues. Therefore an inversion recovery sequence with a short inversion time (TI) of 130-150 is used for fat suppression.
WebIn T1 weighted and proton density weighted sequences, there is a limit to how large the ETL can be (e.g. a usual ETL for T1 weighted images is between 3 and 7). The use of large echo train lengths with short TE results in blurring and loss of contrast. For this reason, T2 weighted imaging profits most from this technique. WebApr 4, 2024 · The median ADC was 1.62 × 10 –3 mm 2 /s for the Tis-T1-T2 group and 2.01 × 10 –3 mm 2 /s for the T3-T4 group, and the difference between the 2 groups was statistically significant (P = .02). In the ROC analysis, the area under the curve was 0.780, with a 95% confidence interval of 0.595 to 0.965, when the cutoff value of ADC was set at 1. ...
WebMar 9, 2024 · The Dixon method, also known as the Dixon technique, is an MRI sequence based on chemical shift and designed to achieve uniform fat suppression.
