Preoperative 3D Magnetic Resonance Imaging in Breast Cancer: The Images Surgeons Would Like to See

Introdução e objetivo(s)

Introduction:
3D reconstruction from Magnetic Resonance Imaging (MRI) in the preoperative planning of breast cancer helps to improve the understanding of the spatial configuration of the anatomical areas of the breast. It contributes to reducing surgical time, helps to reduce postoperative complications, and helps to improve margins of resection of lesions. Consequently, this enhances the speed and accuracy of the surgeon’s interpretation, based on the precision of the MRI and their 3D reconstructions.
MRI provides information on tumor dimensions, proximity to the skin, the CAP, the pectoralis major muscle, and the blood supply, by visualizing the distribution of perforators, as well as the location of lymphadenopathies. It offers a more detailed preoperative image, improving surgical outcomes and enabling a more planned and targeted dissection.
Objectives:
To determine the usefulness of 3D reconstruction MRI in the preoperative planning of breast cancer surgery.

Método(s)

Based on our experience and in accordance with the literature, we have described the contribution of 3D model breast MRI in preoperative planning.

Discussão

3D reconstruction MRI in preoperative planning for breast cancer helps guide the surgeon’s path as a non-invasive digital method, improving visualization and localization of the tumor, proximity to the skin, pectoralis major muscle, and the blood supply. Additionally, it is very helpful for tumors that are not palpable or cannot be precisely measured using other methods. Although 3D reconstruction MRI is useful for understanding tumor anatomy and dimensions, the most obvious limitation is the prone position of the patient during the MRI. Breast MRI in the supine position is likely to provide a more accurate roadmap, as the surgeon could better appreciate the structures as the patient is positioned in the operating room.

Conclusões

The 3D reconstructions MRI helps to reduce the surgeon’s eye fatigue, improve understanding and evaluation of preoperative images, and enhance the speed and accuracy of excision and reconstruction, particularly in high-risk patients and those with complex tumor localization.
