For small volume lesions (up to 4-5 cc) full doses can probably be given (e.g. 22-24Gy, if over the motor strip 22Gy) for somewhat larger (5-8cc) the dose can be dialed down a bit (20-22Gy, but it may be useless to treat radioresistant mets to < 20Gy) for larger lesions (>8cc) then lower doses (16Gy) may be necessary.

Jan 4, 2008 · The AVMs with volumes ranging from 10 to 20 cm3 were also associated with a lower obliteration rate in children at 48 months, but statistical significance was not reached (p = 0.279). Conclusions: Gamma Knife surgery is an effective and safe treatment alternative for pediatric AVMs. The medium (3-10-cm3) and large (10-20-cm3) AVMs tend to We recommend gamma knife radio-surgery as a planned “boost” after surgery and radiotherapy (Fig. 3).
