IMPACT study


The IMPACT study is going to be an international multi-centre retrospective study of patients with an incidental intracranial meningioma. The primary aim of the study will be to externally validate and calibrate a prognostic model of radiological and clinical progression – IMPACT (Incidental Meningioma: Prognostic Analysis Using Patient Comorbidity and MRI Tests)  

The study will include patients with an incidental intracranial meningioma diagnosed between 01/01/2009 and 31/12/2010. Data will be recorded until death or last date of follow-up.


The study is due to begin in September 2020 and we are now asking for local collaborators to sign up.
