No signal change was subjectively seen except for bone marrow in STIR and in TSE T2 sequences. Subjectively, at T24h, trabecular bone appeared slightly hypointense compared to T0 in the TSE T2 sequence and slightly hyperintense compared to T0 in the STIR sequence (Fig. 1 and Fig. 2).

No signal change was seen subjectively except for bone marrow that appeared slightly hyperintense in STIR and slightly hypointense in TSE T2 sequence after refrigeration compared to day 0. Using quantitative analysis, significant SNR changes in bone marrow of refrigerated limbs compared to day 0 were detected in STIR and TSE T2 sequences.

Granulation tissue, soft tissue inflammation and sinus tracts are all T1 hypointense, T2 and STIR hyperintense and enhance with gadolinium. Brodie’s abscesses are usually metaphyseal and appear as a fluid filled cavity with an enhancing lining, rim of low signal sclerosis and peripheral edema (Figure 10).

Aug 25, 2019 · - strongly T2 weighted GRE sequence → combination of high signal levels and extremely high spatial resolution (excellent tissue/fluid contrast); flow-compensated, 2- or 3-dimensional gradient echo acquisition to obtain images with contrast that is proportional to the ratio of T2 relation time to T1 relaxation time → high signal-to-noise and ...

Using a balloon injured porcine coronary artery, we examined whether edema as a sign of inflammation could be detected in the vessel wall by MRI using a T2-STIR (known to detect edema). After injury, the T2-STIR images showed a significant increase in vessel wall enhancement of 143% (CI95 = [39.6 - 142.5]; and areas with signal enhancement ...

(C-F) Corresponding sagittal slices of the same joint in the same slice location shown in (C) STIR, (D) T2W-FSE, (E) T2*W-GRE and (F) T1W-GRE sequences. A focal cartilage lesion (white arrow) appears hyperintense in all sequences, which was unexpected in T1W-GRE images since fluid signal was expected to be hypointense.

Short T1 inversion recovery (STIR) sequences provide fat-suppressed images with T1- and T2-additive effects (see the image below). STIR sequences are particularly useful for the detection of small lesions and bone marrow abnormalitiesShort T1 inversion recovery (STIR), coronal magnetic resonance image shows the lesion's extent and a large, soft ...

Depending on the character of the lesion, the T2 gradient echo ,STIR , T2 fast spin echo and proton density are useful for fluid accumulations, where in SPGR , T2 gradient echo , proton density and T2 fast spin echo are useful for shape defects , bone and cartilage defects.
