BOLD-MR Angiography as a Diagnostic Tool for Asymptomatic Cavernomas in Children

Purpose: The purpose of this study was to evaluate the diagnostic potential of a high resolution MR venography technique in a child with asymptomatic cerebral cavernomas. The blood oxygen level dependent (BOLD) venography method is based on susceptibility-induced phase contrast and is sensitive not only to the oxygen content of intravascular blood but also to breakdown products such as hemosiderin, due to increased signal dephasing. Methods and Materials: We studied a 12-month-old asymptomatic girl with a history of familiar multiple cavernomas. Imaging was performed on a 1.5 T MR unit (Siemens, Vision plus) usi…
