| Brain Protocol |
Hi Oscar,
depending of the indication (tumor, stroke, haemorrhage, epilepsy, inflammation, malformation....) different sequences are useful for brain MRI.
A protocol for a wide range of indications: sagittal T2, coronal Flair, transversal DWI and transversal T1 without and with contrast medium. In case of a result a second plane of a T1 sequence after contrast e.g. coronal is recommended.

| Moire fringing |
Moire fringes are typical for gradient echo sequences, especially balanced sequences like for example true fisp, bFFE. The reasons are interferences and field inhomogeneities. High order shimming (volume shimming), a more suitable coil, a smaller bandwidth, and scanning not in the edges of the magnetic field will avoid or reduce this artifact. Also parallel imaging techniques can have a positive influence. If this artifact appears, also by using other sequences, a new field adjustment can be necessary (service).
Hope this will help.
