Extrapleural solitary fibrous tumor-a revision of three cases.

Extrapleural solitary fibrous tumors are a rare type of spindle cell neoplasm, which can occur in many locations with different histologic and immunohistochemical findings, making the diagnosis challenging. They are usually indolent and their treatment is based on complete surgical resection. There are still some issues to be clarified regarding systemic therapy (specifically when aggressive behavior exists) and long-term follow-up.

Specific absorption rate in neonates undergoing magnetic resonance procedures at 1.5 T and 3 T.

MRI is finding increased clinical use in neonatal populations; the extent to which electromagnetic models used for quantification of specific absorption rate (SAR) by commercial MRI scanners accurately reflect this alternative scenario is unclear. This study investigates how SAR predictions relating to adults can be related to neonates under differing conditions when imaged using 1.5 T and 3 T MRI scanners.
