A Customizable Multimodality Imaging Compound That Relates External Landmarks to Internal Structures.

Area of Science:

• Medical Imaging
• Biomedical Engineering
• Surgical Navigation

Background:

• Accurate localization of internal anatomical structures is crucial for numerous medical interventions, including drug delivery, surgery, and diagnostics.
• Individual anatomical variations pose challenges for traditional stereotactic procedures relying on external landmarks and standardized atlases, potentially leading to errors like incorrect craniotomy placement.
• Existing methods often lack flexibility and consistent visibility across different imaging modalities.

Purpose of the Study:

• To develop an easy and accurate method for correlating external landmarks with medical scans of internal organs, particularly the brain.
• To create a versatile compound that provides a reliable external reference point for internal structures.

Main Methods:

• Introduction of a novel compound visible across multiple imaging modalities: Magnetic Resonance Imaging (MRI), Computed Tomography (CT), and radiography.
• Application of the compound to any surface to establish an external reference point linked to internal, non-visible structures.

Main Results:

• The compound demonstrated consistent visibility (same color) across different scan types (MRI, CT, radiography) when tested on nonhuman primates and isolated brain scans.
• This consistent visibility facilitated practical application in medical imaging and surgical planning.
• Compared to conventional contrast agents, the developed compound offered superior and consistent performance without differential coloring or failure to appear, and exhibited greater flexibility.

Conclusions:

• The compound is customizable in properties such as viscosity, color, and odor.
• It can be integrated with hardening materials for industrial applications or embedded with medical equipment like laparoscopy wands and electroencephalogram leads to enhance 3D visualization.
• A pending U.S. patent signifies the novelty and potential impact of this invention.
