The purpose of this exhibit is to present the pitfalls of generating MR fiber g-ratio mapping in neurological disease patients, and to propose possible solutions. While the g-ratio maps can help to make comprehensive diagnosis together with clinical information (i.e. symptoms), probable differential diagnosis and conventional MR imaging findings can help to avoid the misuse of MR fiber g-ratio maps in the clinical setting.
