Application of Multimodal Image Fusion 3D Reconstruction Technology Combined with 3D Printing Guide Plate in Meningioma Surgery

Abstract

Objective

To explore the value of multimodal image fusion three-dimensional (3D) reconstruction technology combined with 3D-printed guide plates in meningioma surgery.

Methods

The clinical data of 16 patients with meningioma who underwent tumor resection at Taizhou People's Hospital between November 2022 and May 2024 were retrospectively analyzed. Preoperative thin-layer computed tomography and magnetic resonance imaging examinations were performed on all patients. Multimodal image fusion and 3D reconstruction were performed on the computed tomography and magnetic resonance imaging data using the 3D Slicer software to create 3D models of the skin, muscle, skull, tumor, cerebrovascular structures, and other relevant anatomical features. These models were used to develop optimal surgical plans and design 3D guide plates. The 3D printing guide promoted precise localization of the tumor on the body surface, assisted in the design of the bone flap and scalp incision, and identified key surgical landmarks. General data, results of multimodal image fusion 3D reconstruction, accuracy of the 3D printing guide, intraoperative data, surgical complications, and follow-up outcomes for all patients were summarized.

Results

The surgical approach was successfully planned, and 3D-printed guide plates were created preoperatively based on the multimodal image fusion and 3D reconstruction models. The 3D guides enabled precise body surface localization of the tumor and full exposure of the tumor and peritumoral tissue with the smallest possible bone window. Multimodal image fusion 3D reconstruction images promoted the successful protection of important cerebrovascular structures and brain tissue during surgery. All 16 procedures were successfully completed, with the 3D reconstructed images closely matching the intraoperative observations. The tumor was accurately located beneath the incision and postoperative imaging confirmed complete lesion removal.

Conclusions

Multimodal image fusion combined with 3D printing guide technology provides precise localization for meningioma resection, aids in understanding the position of cerebrovascular structures and the skull, prevents deviations in the surgical pathway, optimizes the surgical process, predicts potential intraoperative challenges, increases the success rate of surgery, and decreases the rates of complications and recurrence.
