・髄膜腫手術における基本は4D(detachment,devascularization,debulking,dissection)である.
・4Dを検討する上で,3次元画像を用いたシミュレーションは有用である.
・ただし,元画像で描出できないものは3次元画像上でも描出はできないことを忘れてはならない.

The basics of meningioma surgery are represented in the ‘4Ds’: Detachment, Devascularization, Debulking, and Dissection. When considering the 4Ds, surgical simulation using 3D images is useful, as it allows the surgeon to understand the 3D relationship between the tumor, feeding vessels, and surrounding tissues. However, the hardness of the tumor and the degree of adhesion between the tumor and surrounding tissue are difficult to determine based on 3D images, and must therefore be confirmed using MRI, such as T2-weighted images.
