Diagnosing dural metastases: the value of 1H magnetic resonance spectroscopy.

abstract：PURPOSE:Pineal cysts are common incidental findings in children undergoing magnetic resonance imaging (MRI). Several studies have suggested MRI follow-up if the cyst is larger than 10 mm. However, cysts do not usually change during follow-up. Prevalence, growth, and structure of the pineal cysts were analyzed to decide...
