Inaccurate visual grading systems in neuroradiology: Topic highlights

Abstract

There are many visual grading systems that have been used in neuroradiology like medial temporal lobe atrophy scale, global cortical atrophy scale, posterior atrophy rating scale of parietal atrophy, Fazekas scale, thrombolysis in cerebral infarction scale, etc. All these grading systems do not have any measurable values or grades based on numerate values. Instead, these grading systems depend on a personal opinion and visual estimation. This paper focus on the accuracy, practicality, and usability of these grading systems.
