Noncontrast magnetic resonance imaging for preoperative perforator mapping

Area of Science:

• Medical Imaging
• Surgical Planning
• Anatomy

Background:

• Preoperative identification of the dominant perforator's position, course, and caliber is crucial for successful perforator surgery.
• Current imaging techniques may have limitations regarding cost, availability, reproducibility, or patient safety (e.g., radiation, contrast agents).

Purpose of the Study:

• To evaluate noncontrast magnetic resonance imaging (MRI) as an ideal preoperative imaging method for perforator surgery.
• To present the authors' experience with noncontrast MRI for perforator identification.

Main Methods:

• Utilizing multidetector-row computed tomography (MDCT) and magnetic resonance imaging (MRI) for detailed assessment of perforator anatomy.
• Focusing on noncontrast MRI to avoid patient radiation and the need for intravenous contrast agents.

Main Results:

• Both MDCT and MRI provide easily interpretable images.
• Noncontrast MRI effectively assesses perforator caliber, localization, intramuscular course, and anatomical relationships.
• This method is reliable, cost-effective, readily available, reproducible, fast, and easy to interpret, with no associated morbidity.

Conclusions:

• Noncontrast MRI is a valuable, safe, and efficient tool for preoperative perforator mapping.
• This technique offers significant advantages over traditional methods, enhancing the planning and execution of perforator surgery.
