摘要: Object The authors sought to assess the relationship between obliteration rate and different dose parameters following fractionated radiotherapy for arteriovenous malformations (AVMs). A comparison of results radiosurgery AVMs was made calculate best fit α/β value, which would then be used as a model predicting treatment outcome, independent number fractions applied. Methods Data from 1453 patients were analyzed: 1154 treated with 300 radiotherapy. relationships after 3 years calculated, curve empirical defined. higher per fraction, biologically effective dose, lower total rate. isoeffective doses when comparing value could not fraction had predictive fracti...
