Rationale And Objectives:
Cavernous malformations (cavernomas) occur in 0.4%-0.9% of the population. The most common symptoms of cavernous malformations are seizures. An improved detection of small cavernomas might possibly help to clarify cryptogenic seizures, which represent 30% of all seizures. The aim of this study was to evaluate the benefit of magnetic resonance imaging at a field strength of 7 T in the detection of cavernomas.
Materials And Methods:
Ten consecutive patients with known cavernomas were enrolled in this study. First a T2*-weighted gradient echo sequence was performed at 1.5 T with a slice thickness of 6 mm in axial orientation. Subsequently, the examination was repeated at 7 T. Both examinations were independently read by two blinded senior neuroradiologists. Localization and dimension of the hypointensities were recorded.
Results:
One additional hypointensity was detected in one patient, which was not visible in the 1.5 T examination even retrospectively. In another patient with known cavernomatosis, innumerable new small hypointense lesions were detected at 7 T.
Conclusion:
Our small series suggests that ultra-high-field magnetic resonance imaging at 7 T improves the detection of cavernomas.
