Comparison of flow artifacts between 2D-FLAIR and 3D-FLAIR sequences at 3�T

Abstract: It has been reported that 3D-FLAIR can reduce the flow artifact resulting from cerebrospinal fluid (CSF) at 1.5 T compared to 2D-FLAIR. Flow-related artifacts tend to be worse at 3 T than at 1.5 T. The purpose of this study was to compare the CSF flow artifacts of 2D-FLAIR and 3D-FLAIR sequences at 3 T in eight healthy volunteers. The grade of CSF-related artifacts were scored through observing the perimedullary cistern, cerebellopontine angle cisterns, fourth ventricule, prepontine cistern, suprasellar cister… Show more

“…[13][14][15][16][17] Furthermore, 3D-FLAIR imaging can minimize the undesired inflow artifacts of CSF flow, has a higher signal-tonoise ratio and spatial resolution, and allows recognition of subtle compositional changes of the inner ear fluid. [18][19][20][21] Therefore, one can assume that the increased protein content in the cochlear perilymph of patients with ANs can be detected on 3D FLAIR imaging with a high sensitivity and good spatial resolution. Several researchers recently investigated whether there was a correlation between the increased cochlear FLAIR signal in patients with ANs and the degree of their hearing disturbance.…”

“…1,2 3D-FLAIR imaging can minimize the undesired ghosts of CSF flow 3 and enable recognition of the subtle compositional changes in lymph fluid in the inner ear. [4][5][6] In addition, increased signal intensity of the diseased inner ear can also be observed on 3D-FLAIR imaging shortly after IV gadolinium injection; this technique has been reported to be useful for pathophysiologic analysis of the inner ear in many auditory diseases, such as sudden SNHL, cholesteatoma, cochlear otosclerosis, and vestibular schwannoma.…”
