Keywords: Tumors (Pre-Treatment), Diffusion/other diffusion imaging techniques, Meningioma, Embolization, IVIM
Motivation: Some studies have reported decreased tumor volume and blood flow after preoperative endovascular embolization in meningioma, but it remains unclear how the meningioma and peritumoral edema are altered after endovascular embolization, and a practical evaluation method has not been established.
Goal(s): We investigated IVIM analysis to evaluate perfusion and diffusion simultaneously before and after endovascular embolization in supratentorial meningioma.
Approach: We assessed IVIM parameters (FD*, F, D*, and D) before and after endovascular embolization in supratentorial meningioma.
Results: FD* and F were significantly lower after endovascular embolization in meningioma than those before the endovascular embolization.
Impact: The IVIM analysis makes it possible to evaluate perfusion and diffusion simultaneously after preoperative endovascular embolization in supratentorial meningiomas in a short time.
