MRI is becoming an increasingly valuable non-invasive tool in ocular tumour assessment and treatment planning. ophthalmology. High resolution images acquired at high field provide multi-dimensional information on tumour size. However, image quality is often compromised by eye motion which is often triggered by gradient noise In the present work the use of magnetization prepared 3D Zero Echo Time imaging (ZTE) is proposed, enabling for almost silent volumetric scanning at isotropic resolution. An initial validation showing the potential of the ZTE approach at 7T for is shown in volunteers and tumour patients.
