WebT2* can be considered an "observed" or "effective" T2, whereas the first T2 can be considered the "natural" or "true" T2 of the tissue being imaged. T2* is always less than or equal to T2. T2* results principally from inhomogeneities in the main magnetic field.

WebMar 24, 2024 · The T2W TSE sequence used the maximum TSE factor, which had a voxel size of 0.9 × 0.91, a TR of 4500 ms, and a TE of 110 ms. SENSE was used to reduce scan time. T2W FLAIR used the maximum TSE factor, a voxel size of 1 × 1.2, a TR of 6000 ms, and a TE of 120 ms. The SENSE factor was 1.6. WebThe sensitivity of T2 TSE and FLAIR for microhemorrhage was 12.5%. The Fisher exact test showed a statistically significant difference in the differentiation of VS from meningioma on the basis of detection of microhemorrhages (P <.01). CONCLUSION: Most VS demonstrate microhemorrhages on T2*-weighted GRE. This finding is useful to differentiate ...
