Area of Science:

Medical Imaging
Surgical Oncology
Computer-Assisted Surgery

Background:

Musculoskeletal tumor resections require precise preoperative planning.
Integrating multiple imaging modalities can improve visualization and analysis.
Computer-assisted surgery offers potential for enhanced precision in tumor removal.

Purpose of the Study:

To evaluate the efficacy of image fusion of computed tomography (CT) and magnetic resonance imaging (MRI) for preoperative planning in computer-assisted bone tumor surgery.
To assess the accuracy and time efficiency of the image fusion process.
To determine the clinical benefits of using fused images with surgical navigation.

Main Methods:

Image fusion of CT and MRI was performed for 13 patients undergoing complex musculoskeletal tumor resections.
Software was used to integrate preoperative imaging data.
Intraoperative registration and navigation guidance were employed during surgery.
Postoperative validation included CT scans and histologic examination of resected specimens.

Main Results:

Visual verification of fused images was accurate in all cases.
The mean image fusion time was 30.6 minutes.
All tumor resections were performed successfully as planned under navigation guidance.
Histologic examination confirmed tumor-free margins in bone sarcoma patients.

Conclusions:

Image fusion of CT and MRI is a valuable technique for enhancing preoperative planning in computer-assisted bone tumor surgery.
The fused images, combined with surgical navigation, aid surgeons in reliably reproducing preoperative plans.
This integrated approach offers potential for substantial clinical benefits in bone tumor treatment.
