Abstract:

The new pulse sequence (PS) has been obtained on MRI tomography Ellipse, B=0,15 and Biospec 70/30, B=7 T. The new pulse images of the brain combine features of FLAIR and its sensitivity to magnetic field heterogeneity. We named its PS as the T2 Fluid Attenuation Gradient Echo (T2 FLAGE). The T2 FLAGE characteristics of tissue contrast as well as its efficacy in detection of ICH have been assessed in 57 patients with acute stroke and in 16 experimental rats. The analysis of tissue contrast of lesions and normal brain structure has revealed the greater visibility of T2 FLAGE images compared to FLAIR. At the same time, the images sensitivity of magnetic field heterogeneity is retained. The ROC-analysis has shown that T2 FLAGE images are more effective in differential diagnosis of stroke type compared to FLAIR.
