External Email - Use Caution Dear Experts,
For our project work, we particularly looking for hippocampal and its subfield volumes. Using GE 1.5T scanner, we tried a 3D BRAVO sequence with 1x1x1 resolution, 256x256x160 dimension with 8* flip angle which produced images with a lot of noise. Then we tried the same sequence with 1x1x2 resolution, and 256x256x80 FOV, which produced a clean image without noise. When we reformatted the images, it produces 0.5x0.5x1 resolution with 512x512x172 dimension. Is this sequence good for hippocampal volume estimation and subfield segmentation (also for whole-brain VBM analysis)? Could you please suggest to me a correct sequence for our project? Regards Ramesh
