Human eye magnetic resonance imaging relaxometry in diabetic retinopathy

摘要

Two quantitative ocular magnetic resonance imaging (MRI) methods for theclinical use in Ophthalmology and Radiology were developed. Ocular MRI images withspatio-temporal resoultions of 0.78/1.56/2/(5 to 84) mm/mm/mm/s were acquired frompatients with diabetic retinopathy and normal subjects using a 1 T MRI system. T1 andT2 MRI relaxometry maps were generated offline from the MRI images acquired.Statistically significant differences between the T1 values of the normal and disease- affected groups were found. Useful qualitative and quantitative ophthalmological,radiological and surgical information covering the whole eye can be achieved usingnoninvazive MRI techniques.
