Posterior lumbar apophyseal ring fractures: a report of 20 cases.

abstract：INTRODUCTION:The DWI/FLAIR mismatch is a potential radiological marker for the timing of stroke onset. The aim of the study was to assess if the DWI/FLAIR mismatch can help to identify patients with both lacunar and nonlacunar acute ischemic stroke within 4.5 h of onset. METHODS:A retrospective study was performed in ...
