Brain imaging evaluates lesions prior to microvascular decompression surgery


  • Pre-operative imagine techniques 3-dimensional brain volume (3D-BRAVO) and 3-dimensional time-of-flight (3D-TOF) magnetic resonance angiography (MRA) correctly predicted intraoperative findings in terms of morphology, location and anatomy of lesions.

Why this matters

  • The success of microvascular decompression, used to treat primary trigeminal neuralgia and hemifacial spasm, can depend on detailed preoperative evaluation of the lesion. The imaging techniques evaluated in this study could help characterize the lesion prior to surgery, increasing the chance of a successful outcome.
