GRE T2*WI is more useful for the diagnosis of a disease when combined with conventional MRI sequences, and GRE T2*WI will be widely used in clinical applications.

Conventional chemical shift dual echo GRE T1W and TSE-STIR images will demonstrate the liver signal intensity drop, allowing the qualitative diagnosis of significant iron deposits (Fig. 16).
Let us finally remark that as a usual consequence of the General Relative Entropy principle (GRE) [29], the estimate (4.4) follows by choosing the convex function G ( x ) = ( x − C 0 ) + 4.
Deoxyribonucleotides probes containing consensus glucocorticoid response element (GRE): 5-CTAGGCTGTACAGGATGTTCT-GCCTAG-3 and 5-CTAGGCAGAACATCCTGTACAGCCTAG-3 were synthesized and annealed.
Compared to ChIP-reChIP using IgG control antibodies, ChIP-reChIP using GR and then p300 showed significant enrichment of the DUSP1 GRE (23 fold, Fig. 6D).
When located in the 3'UTR ARE (DE2), GRE (DE3), and CA-rich (SE2) sequences are most significant in determining mRNA half life in C2C12 cells.
In thirty consecutive stroke service patients, standard GRE T2* images were acquired and manually rated for microbleeds by a trained observer.
After spatially normalizing each patient's GRE T2* images into a standard stereotaxic space, the automated microbleed detection algorithm (MIDAS) identified cerebral microbleeds by explicitly incorporating an "extra" tissue class for abnormal voxels within a unified segmentation-normalization model.
Cerebral microbleeds are small, rounded areas of homogeneous low signal visualized on GRE T2*-weighted images because haemosiderin (a paramagnetic product of blood degradation) has high magnetic susceptibility, causing local field inhomogeneities and signal loss.
Cerebral microbleeds, visible on gradient-recalled echo (GRE) T2* MRI, have generated increasing interest as an imaging marker of small vessel diseases, with relevance for intracerebral bleeding risk or brain dysfunction.
