Skull Base Meningioma - Comparison of Intensity-modulated Radiotherapy Planning Techniques using the Moduleaf Micro-multileaf Collimator and Helical Tomotherapy

This study shows that safe dose escalation to a dose of 60 G y to skull base lesions can be achieved; using either mMLC- or helical tomotherapy-based IMRT. A plan comparison between the two solutions is difficult, but they seem to be similar in efficacy with any small differences being difficult to interpret and of questionable clinical significance. Helical tomotherapy has the advantage of a significantly decreased beam-on time.
