Purpose Diffusion tensor imaging (DTI) may be helpful in assessing optic pathway integrity as a marker for treatment in neurofibromatosis type 1 (NF1) patients with optic gliomas (OG). However, susceptibility artifacts are common in typical single-shot echo planar imaging (ssDTI). A readout-segmented multi-shot EPI technique (rsDTI) was utilized to minimize susceptibility distortions of the skull...
Purpose Contrast-enhanced MRI (MRI + C) is considered as mandatory for brain tumors follow-up, but gadolinium brain depositions in relation with repeated injections have been reported. The aim of our work was to evaluate the diagnostic performance of an unenhanced MRI examination for the follow-up of optic pathway gliomas (OPG) in children. Methods Seventeen patients (with/without NF1) were selected...
